    The EIM platform lets the user perform successful searches through various methods. In all searches, the user does not need to specify if the search term is a menu item, help page, or data entity such as parameter or location. Rather, the search bar determines the most relevant results based on the data currently in EIM.

    Locus Technologies President, Wes Hawthorne tells us in this video how useful he finds this feature on the EIM platform.

      There is a need for most water entities to centralize data, and more easily load, share, analyze, and report data. Locus Technologies’ customizable software makes scheduling and collecting routine water samples is made easy by using Locus Mobile and EIM. Below is a list of frequent challenges that customers have encountered during their water sampling process and how they can be solved using the right tools from Locus. or better communications. 

      Challenge 1: Finding a flexible sampling planning tool 

      Planning tools need to allow flexibility in terms of different sampling intervals and date ranges, different field and analytical parameters, and account for location grouping. Using a well-designed application can pull together all of this detailed information and can provide a summary view of the individual samples. A manager can easily view sample status, and whether the sample is complete, in process, or planned.  A well-designed application can also generate the chain of custody (COC), and lab and sample shipping date information and labels per sample, which is a huge time saver. This type of sample tracking detail seemed to be very useful to many conference attendees to help ensure they are in regulatory compliance with required sampling frequencies. A key feature to look for is an application that is flexible enough that it can allow one-time, unplanned sample events such as water main breaks, customer complaints and schedule changes, and can handle complex multi-year routine sampling with ease. As a plus, it’s easy for you or your manager to know where you stand at any time.

      Challenge 2: Eliminating data entry errors caused by hand data entry 

      Data entry errors and fixing bad data when it was transcribed from field notes to Excel or other programs is a persistent problem with the old way of doing things.  Your company needs a better way to streamline the error prone data collection process.  Many clients are interested in an alternative to the pencil/paper/clipboard method and had goals to move to tablet or smartphone for data collection.  The universal wish list for mobile field applications included: 

      • Easy to use and set up 
      • Built in data validation to catch data entry errors at the source 
      • Direct upload to a data system so the end of the day all the daily samples were in the system with the push of a button 
      • Prepopulating locations especially for large water systems 
      • Complete field instructions for samplers on what to collect and where to collect it to eliminate missed samples 
      • Smart tracking to know on a daily/weekly basis, what samples were collected and what samples were still outstanding 
      • Integrated with sample planning tools (See challenge 1) to automate the sampling instructions and track the data collection activities vs plan

      Challenge 3: Getting the most out of their software, especially regarding updates 

      Everyone is aware that software updates all the time.  Sometimes its security enhancements and sometime feature enhancements or bug fixes.  A source of frustration is getting a software update and not knowing what was updated or how best to incorporate a new feature/enhancement into their established process.  There was also concern for impact to an established routine with field crews that were used to the existing way of doing things. Even if a functionality improved the workflow, enhancements are only valuable to a user if they understand how to use them and how to incorporate them into their existing process. 

      Some suggestions from the attendees included:
      • Concurrent documentation updates with software updates 
      • “Quick start” guides for new functionality 
      • Online training on the new functionality with recording for later viewing 
      • Heads up on what is coming in the next several months so they can do strategic planning (sharing the roadmap) 
      • Sandbox environment to test the enhancements before going in production so they can plan how to incorporate the features into their process and train field crews 

      Mobile applications, which appear very simple to the users, are in reality complex software and require careful integration with the receiving database for a range of complex use cases.  This makes rolling out new mobile features challenging for both the developers and the users.  Enhanced customer/developer communication along with a sandbox environment can go a long way towards solving some of the inherent issues with rapid innovations and updates associated with cloud and mobile software.

          Today is GIS Day, a day started in 1999 to showcase the many uses of geographical information systems (GIS). Earlier Locus blog posts have explained how GIS and maps support visualization of objects in space and over time. This post covers a specific visualization method called data dashboards.  

          A data dashboard is a combination of charts, maps, text, and images that enables analysis of data and thereby promotes discovery of previously unknown relationships in the data. Companies and organizations use dashboards to develop insight into the overall status of a company or of a company division, process, or product line. Dashboards are also a common function in ‘business intelligence’ applications such as Microsoft Power BI and Tableau. A printed dashboard is static, but an online dashboard can be dynamic; in a dynamic dashboard, interacting with one item on the dashboard causes the other items to update. Taken together, the visualizations on a dynamic dashboard can help you find the story in your data. 

          One reason dashboards are so helpful is that they allow humans to partially ‘offload’ their thinking. Cognitive research has shown that human ‘working memory’ handles at most four items at a time. A good visualization, however, reduces the number of items to process in memory. 

          Consider a large table of carbon dioxide emissions by country for multiple years; it can be difficult to keep all the numbers in mind if you are trying to find trends.

          If you plot the data in a graph, however, each series of data in the chart becomes just one line on the graph. It is much easier to compare lines on the chart than to compare columns of numbers.

          Now consider making a map with countries color coded by emissions. Again, for each country, the map reduces multiple numbers to a single color for that country on the map. You can compare country colors more easily than columns of numbers.

          A dashboard that combines multiple visualizations further enhances data analysis. Imagine a dynamic dashboard showing you both the emissions chart and map described above. If you select a country on the map, the chart can highlight the line for that country, so you compare its emissions to other countries over time. Similarly, if you select a line on the chart for a specific country, the map can highlight the selected country to show how its emissions compare to nearby countries. This interactivity lets you drill into your data more effectively than using either the chart or the map by itself.

          Here are three examples of effective dashboards that are available online:

          Locus includes data dashboards in our applications. One example is the Site Metrics dashboard in EIM, Locus’s cloud-based, software-as-a-service application for environmental data management. The Site Metrics dashboard lets you perform roll-up queries across your portfolio of sites. A map on the dashboard shows all states with active sites. If you select one or more states, the dashboard updates the charts and tables on the right to show total sites, user logins, and record counts. Other dashboards can support showing sample locations of certain chemicals or counts of regulatory limit exceedances.

          A further example comes from the Locus Environmental Social and Governance (ESG) application. ESG metrics are becoming increasingly important measures for an organization’s performance. Data dashboards can help companies quickly visualize trends in their ESG metrics using intuitive mapping tools.

          This dashboard illustrates both spatial and time trends and provides the raw data necessary for auditability and transparent decision making. Having these features on a single combined view provides users with instant access to the key inputs for ESG prioritization, planning, and project implementation.

          As these examples from Locus show, data dashboards with integrated mapping are important tools for maximizing the value of your collected environmental and ESG data. For any dataset with a geographic component, it’s important to incorporate mapping elements in the outputs, to highlight trends and patterns that may not otherwise be visible in a chart or table. Modern software can combine these output formats in a way that tells the story shown by your data.

          Today is GIS Day, a day started in 1999 to showcase the many uses of geographical information systems (GIS). Earlier blog posts by Locus Technologies for GIS day have shown how GIS supports cutting-edge visualization of objects in space and over time. This year’s post explains how GIS supports augmented reality.

          Augmented reality (AR) is a technology that enhances how we experience the real world by overlaying your surroundings with computer-generated objects. It differs from virtual reality (VR) because in VR, everything you see is computer generated, but in AR, the majority of what you see is real – your experience of reality is enhanced (augmented) but not totally replaced.

          You are probably familiar with one AR application already if you watch American football. The ‘virtual’ first down line that appears on field before each play is projected there by computer and is not really painted on the field. If you follow soccer (or football to the rest of the world), AR is used by a Video Assistant Referee (VAR) to objectively determine tight offsides decisions. Digital lines are drawn across the field to show whether or not attackers are illegally past the last defender or not. Another AR example is the popular game Pokémon Go that shows cute virtual creatures in your living room or your front yard.

          To experience AR, you need something to project the non-real objects onto your view of the world. Many AR applications use mobile phones or other devices. An AR application uses the camera view to show you the world around you and then overlays virtual objects onto the view. Other devices such as head mounted displays, ‘smart glasses’, or even ‘bionic contact lenses’ can use AR, but have not been as popular as phones or other mobile devices. In contrast to AR, VR cannot be fully supported with just a mobile device and usually requires headsets to immerse you in a virtual world. Because of this need, AR is much less intrusive than VR is.

          Countless other examples of AR already exist in many fields. A few selected applications include:

          • Online shoppers at some e-commerce sites can use smart devices to project furniture into their home to see how the pieces look before making a purchase.
          • Some clothing stores can project clothing onto shoppers’ bodies to check appearance without having to change clothes. These applications require the user to be in a special dressing booth with full body scanning capabilities.
          • Urban planners use AR to display how planned buildings, cell towers, wind turbines, and other structures would look in the existing space. Planners can walk the streets and view how proposed projects would alter the existing cityscape.
          • AR is used in manufacturing to display operation and safety instructions in a worker’s field of vision using head mounted displays, which circumvents the need to refer to bulky paper manuals.
          • Utility managers can see underground pipelines, water lines, sewer pipes, electrical lines, and other infrastructure projected below their feet.

          So how does GIS relate to AR? There are three main uses of GIS in AR:

          • Location: Any AR application must know where the user is and where to place virtual objects. In most cases, full GIS capabilities are not needed; instead, the application accesses a GPS (global positioning system) to find locations. Consider the Pokémon Go application mentioned before. The game knows where the various Pokémon need to appear. When a user plays the game, it uses GPS to find the user, and then shows any Pokémon that are near the user based on their locations.
          • Layers: An AR application may need to show features that are not visible to the user, such as underground electrical lines, earthquake fault lines, property lines, or planned buildings. All these features can be stored as GIS map layers in the cloud and then displayed in the AR application as virtual overlays projected on the real world. Furthermore, a user could select a displayed item and view related attribute information in the GIS layer. For example, a user could view the condition, age, and repair status of a selected water pipeline.
          • Navigation: An AR application may also need to help a user get from point A to point B, for example in a crowded airport or in a large warehouse. Such navigation could be facilitated by showing virtual route markers and arrows on the real world.

          Locus has been exploring environmental uses of AR and GIS by adding AR to Locus Mobile, which is the Locus app for collecting field data, completing EHS audits, tracking waste containers, and completing other tasks requiring users to gather data out of the office. Locus Mobile now features an AR mode to assist users when taking field samples. When the user activates AR mode, the app uses the camera to show the user’s immediate area. The app then puts multiple virtual markers on the display corresponding to sampling points located in that direction. As the user moves or rotates the phone to change the viewing area, the markers change to reflect the locations in the user’s line of sight. Clicking a marker provides more information including the location name and the distance from the user.

          Locus Mobile uses all three ways to combine GIS with AR:

          • By using GPS to find the user’s location and the locations of nearby sampling points.
          • By using GIS to display the layer of sampling points.
          • By using GIS to assist with navigation to sampling points by showing distance and direction.

          Here is a sample image from Locus Mobile showing three nearby sampling locations along with information about past events or measurements at the locations. The three blue banners are the augmented reality displayed on top of the view of the nearby surroundings.

          Locus Augmented Reality

          By using GIS and AR to assist users in finding sampling points, Locus Mobile makes field personnel more productive. Samplers can find field locations quickly and can easily pull up related information. Locus continues to explore using AR to expand the functionality of its environmental applications.

            Today is GIS Day, a day started in 1999 to showcase the many uses of geographical information systems (GIS). Earlier Locus blog posts have shown how GIS supports cutting-edge visualization of objects in space and over time. This post is going to go “back to basics” and discuss what makes GIS unique and how environmental data analysis benefits from that uniqueness.

            Spatial vs Non-Spatial Relationships

            So, what makes GIS unique? It’s the ability of GIS to handle spatial relationships, which goes beyond just putting “dots on a map”. You are probably familiar with non-spatial relationships such as greater than, less than, or equal to, and you probably use them every day. For example, suppose you want to buy the latest gaming console (PS5, anyone?). You need to compare the price of the console to your bank account. If the console price is greater than your savings, then you cannot buy the console.

            Or can you? With credit cards, you can pay later, so you go charge the console. At the time of the transaction, some software evaluates a non-spatial relationship and checks if the console price plus your current debt is less than your credit limit. If so, you can buy the console; if not, your purchase is denied.

            The key point about this example is that spatial relations play no part. It doesn’t matter where you are located or where the game console is sold from. (OK, there may be things like state taxes and shipping, but that just contributes to the price.) Now, if you were trying to find all gaming consoles for sale within a certain distance of you, that is a spatial relationship. There are multiple types of spatial relationship, but the most common are inside, contains, crosses, overlaps, and within a distance of. Standard relational database software does not handle these sorts of relations, but GIS can.

            As an illustration, let’s consider two current events: the 2020 US presidential election and the COVID-19 pandemic. With non-spatial relationships, you can answer various questions such as “did Biden get more votes than Clinton?” or “is the number of positive COVID tests increasing?”. But with spatial relations, you can answer more interesting questions such as “did areas with COVID hot spots vote more predominantly for Biden or Trump?”. For this question you must see if voters lie inside a COVID hot spot; a GIS can perform this analysis and then map the results. While many votes are still being counted, as of this blog post, it appears Trump performed better in COVID hot spots.

            Spatial Relationships in Environmental Data

            Let’s look at some example of spatial relations in environmental data. Assume you have a database of tritium sampling results in water, along with various map layers of natural and manmade features. What kind of spatial relationships can you explore with GIS?

            To answer that, we’ll make some maps with the Locus GIS+ package in EIM, Locus’s cloud-based, software-as-a-service application for environmental data management. All maps shown here display wells with tritium samples, with the wells represented as colored circles. The color scale goes from blue through yellow to red, to indicate increasing tritium results.

            Figure 1 shows an example of an inside spatial relationship. The map answers the question “what wells with tritium results are inside the Mortandad Canyon watershed?”. The watershed is highlighted in blue on the map, and you can easily see the wells inside the watershed.

            Locus GIS | Wells with tritium

            Figure 1: Wells with tritium within a watershed

            Figure 2 shows wells with tritium results that are within a distance of a river. The map answers the question “what wells with tritium results are within 500 ft of the river?”. The river, highlighted in light blue, has a 500 ft buffer shown as a dotted blue line. The wells with tritium that lie within the buffer are shown on the map, so you can check if any high tritium results are close to the waterway.

            Locus GIS | Wells with tritium

            Figure 2: Wells with tritium within a specified distance of a river

            Figure 3 shows another example of within a distance of. Here, the map answers the question “what wells with tritium results are within two miles of a middle school?”. The two-mile radius is shown as a shaded blue circle centered on the school. You can see the wells are confined to the area southeast of the school.

            Locus GIS | Wells with tritium

            Figure 3: Wells with tritium within a specified distance of a school

            These three examples are just a small subset of what can be done with GIS and environmental data. Here are some other questions illustrating the kind of spatial analysis that GIS supports.

            • Have any spill incidents at my site been within a specified distance of a waterway?
            • Do any pipelines at my site cross protected waterways?
            • Do any remediation areas at my site contain wells that have recorded high chemical levels in water?
            • Does the underground plume from a chemical release overlap any aquifers?

            All these examples illustrate the power of GIS for analyzing spatial relationships, and these examples are just the beginning. GIS can also perform more sophisticated analyses that look at spatial relationships in different ways to answer questions such as:

            • How confident can we be in the results of the spatial relationship analysis?
            • Do all data records follow the spatial relationship, or are any outliers that fall outside the norms?
            • Has this spatial relationship changed over time? Has the relation grown stronger or weaker?
            • Can we predict the future of the spatial relationships?

            Locus continues to bring new analysis tools to our Locus GIS+ system for environmental applications. These applications let you take advantage of the unique ability of GIS to analyze spatial relationships in your environmental data.

            Acknowledgments: All the data in EIM used in the examples was obtained from the publicly available chemical datasets online at Intellus New Mexico.

            Visualize environmental data with Locus EIM.

            You’ve probably heard the saying “A picture is worth a thousand words”. While the advice seems timeless, it actually is fairly modern and started with newspaper advertisements from the 1910s. Furthermore, it’s only since the 1970s that cognitive science has caught up and determined the truth in the saying. Basically, humans have very limited working memory, which is the “storage space” for processing data while making decisions and reasoning through problems. A good picture, though, works as “offline storage” that lets you push information out of your limited working memory and into another format for use as needed. This advantage is especially true when the picture is a useful data visualization such as a chart or map. In this case, you could say “A visualization is worth a thousand data points”.

            How limited is working memory? There is a rough consensus, known as Miller’s law, that you can only have “seven, plus or minus two” items in memory at one time. Think of a typical 10-digit phone number that you may need to memorize for a short period. It can be hard to remember all ten individual digits as one large number, as that exceeds working memory. However, you can employ a technique called “chunking” to group items together, reducing the number of items to remember. If you group the phone numbers into the typical ###-###-#### pattern, you only have to remember 3 chunks of 3 to 4 items. A good visualization not only stores information offline, reducing pressure on your brain; it also groups many data items into a much smaller number of chunks so you can process the data more efficiently.

            Let’s look at some real examples of how visualizations help by working through a typical scenario using EIM, Locus Technologies’ cloud-based application for environmental data management. Assume you manage a site where you are tracking tritium (H-3) levels in groundwater using a set of monitoring wells. You want to know where tritium has been high over the past ten years. EIM provides different visualizations for exploring your data and finding the answers you need.

            First let’s just look at an export of all the data. Using the analysis functions in EIM, you search for all tritium concentrations from monitoring wells for the past ten years. EIM sends the results to a table as shown in Figure 1.

            Tabular view of Tritium query results in Locus EIM

            Figure 1 Tabular view of Tritium query results

            The table has 717 results for multiple wells. It is very difficult to see overall patterns here, either spatially or temporally. Each of the 717 results is one item, and if you try to scroll and sort the table to see if tritium is increasing or decreasing over time, your working memory is quickly overwhelmed. This is where a good data visualization can help.

            To start, you decide to send the data to the Locus GIS+ application, using the graduated color and size options. The GIS+ takes the concentrations from the results table and plots them on a site map using the stored coordinates for each well, as shown in Figure 2. The map represents each location with a symbol that is colored and sized to reflect the actual maximum value at that location. The map legend shows you how this was done. Large red circles, for example, represent results from 4,500 to 7,000 pCi/L. As the sizes get smaller, and the colors go from red to blue, the actual result gets smaller.

            Graduated symbol and color map in Locus EIM

            Figure 2 Graduated symbol and color map of tritium concentrations

            This map is great for showing spatial patterns in the data. You can easily pick out a couple of “areas of concern” near the center of the map – one with orange and yellow circles, and another with red circles. To revisit our discussion on working memory and chunks, the map takes the 717 results and summarizes them so your brain can quickly pick out the two areas of concern.

            Let’s look more closely at the area of concern with higher results. If we zoom in on the map, we see the two red locations are wells MCOI-5 and MCOI-6 as shown in Figure 2.

            Zoomed map for one area of concern in Locus GIS+

            Figure 3 Zoomed map for one area of concern

            The map shows you where these two high concentrations of tritium are located. But what if you want to see how the concentrations vary over time? You can make a time series chart in EIM for these wells and include a desired regulatory limit, as shown in Figure 4. The green and blue lines represent the tritium concentrations over time for the two wells. The red line at top shows a regulatory action limit.

            Line chart in Locus EIM

            Figure 4 Line chart showing time series for tritium for two wells, with action limit

            The chart shows you two important things. First, and most importantly, all the tritium concentrations for both wells lie well below the regulatory action limit! Second, the concentrations have very different trends for the two wells: MCOI-6 started higher but has trended lower, while MCOI-5 started below MCOI-6 but has now surpassed it. You can confirm these general impressions by running concentration regression charts in EIM for the two locations, as shown in Figure 5. The charts show the best fit regression line and the strength of the relation.

            Figure 5 Concentration regression charts in EIM

            You can grasp these facts quickly because the of how the chart works. Each series of concentrations for a well consists of multiple data items that are ‘chunked’ into one line on the chart. There are two many individual data points on this chart for your working memory, but only three lines, which can easily be manipulated in your brain. For comparison, Figure 6 shows the actual data values for the chart. The time trends shown above in the charts are not as obvious from the table.

            Data values in Locus EIM

            Figure 6 Actual data values for the chart in Figure 4

            Now, this might be counter-intuitive, but what if you wanted to put some of these values on the map? While visualizations do help understand data, sometimes it can be useful to have the data shown as well so viewers can see where the visualizations came from. The EIM Data Callouts function can do this. Figure 7 shows data callouts for the two wells. Each callout shows the maximum annual tritium result for 2010-2020. Now you have the actual tritium concentrations located spatially next to the matching wells!

            Data callouts in Locus GIS+

            Figure 7 Data Callouts in EIM GIS+

            Now that you know where your tritium might be a concern, suppose you want to see what’s going on with groundwater at your site. The EIM contouring module does that for you. There are multiple contouring options, but for this example let’s use the default options for kriging. We know from Figure 2 that the wells MCOI-5 and MCOI-6 are located in the Mortandad Canyon. Figure 8 shows the contouring map generated from EIM for the groundwater wells in that canyon, using the most recent groundwater levels. Higher groundwater values are lighter in color than lower values.

            The area of concern is marked with an arrow at upper left. The contour lines and values can help you determine how the tritium might migrate in your site. Imagine trying to picture this just using tables of groundwater readings! With the contour map, the readings turn into lines that can be chunked together for analysis: the higher levels at the upper left forming a “plateau”, the closely packed lines moving across the map to the east, and then the “saddle” area at lower right. These different line patterns carry particular meanings to engineers and scientists who interpret contour maps.

            Figure 8 Contour map for groundwater levels

            The contour map completes our tour of some of the visualization tools in EIM. Because visualizations let you chunk items together, you can look at the ‘big picture” and not get lost in tables of data results. Your working memory stays within its capacity, your analysis of the information becomes more efficient, and you can gain new insights into your data.

            Let’s look back on the most exciting new features and changes made in EIM, Locus’ environmental data management software, during 2019!

            1. Migration to AWS Cloud

            In August, Locus migrated EIM into the Amazon Web Services (AWS) cloud. EIM already had superior security, reliability, and performance in the Locus Cloud. The move to AWS improves on those metrics and allows Locus to leverage AWS specific tools that handle big data, blockchain, machine learning, and data analytics. Furthermore, AWS is scalable, which means EIM can better handle demand during peak usage periods. The move to AWS helps ensure that EIM remains the world’s leading water quality management software.

            2. SSO Login

            EIM now supports Single Sign-On (SSO), allowing users to access EIM using their corporate authentication provider. SSO is a popular security mechanism for many corporations. With SSO, one single login allows access to multiple applications, which simplifies username and password management and reduces the number of potential targets for malicious hacking of user credentials. Using SSO with EIM requires a one-time configuration to allow EIM to communicate with a customer’s SSO provider.

            Locus Single Sign On (SSO)

            3. GIS+ Data Callouts

            The Locus GIS+ solution now supports creating data callouts, which are location-specific crosstab reports listing analytical, groundwater, or field readings. A user first creates a data callout template using a drag-and-drop interface in the EIM enhanced formatted reports module. The template can include rules to control data formatting (for example, action limit exceedances can be shown in red text). When the user runs the template for a specific set of locations, EIM displays the callouts in the GIS+ as a set of draggable boxes. The user can finalize the callouts in the GIS+ print view and then send the resulting map to a printer or export the map to a PDF file.

            4. EIM One

            For customers who don’t require the full EIM package, Locus now offers EIM One, which gives the ability to customize EIM functionality. Every EIM One purchase comes with EIM core features: locations and samples; analytical and field results; EDD loading; basic data views; and action limit exceedance reports. The customer can then purchase add-on packages to get just the functionality desired–for example a customer with DMR requirements may purchase the Subsurface and Regulatory Reporting packages. EIM One provides customers with a range of pricing options to get the perfect fit for their data management needs.

            5. IoT data support

            EIM can now be configured to accept data from IoT (internet of things) streaming devices. Locus must do a one-time connection between EIM and the customer’s IoT streaming application; the customer can then use EIM to define the devices and data fields to capture. EIM can accept data from multiple devices every second. Once the data values are in EIM, they can be exported using the Expert Query tool. From there, values can be shown on the GIS+ map if desired. The GIS+ Time Slider automation feature has also been updated to handle IoT data by allowing the time slider to use hours, minutes, and seconds as the time intervals.

            6. CIWQS and NCDEQ exports

            EIM currently supports several dozen regulatory agency export formats. In 2019, Locus added two more exports for CIWQS (California Integrated Water Quality System Project) and the NCDEQ (North Carolina Department of Environmental Quality). Locus continues to add more formats so customers can meet their reporting requirements.

            7. Improved Water Utility reporting

            EIM is the world’s leading water quality management software, and has been used since 1999 by many Fortune 500 companies, water utilities, and the US Government. Locus added two key reports to EIM for Water in 2019 to further support water quality reporting. The first new report returns chlorine averages, ranges, and counts. The second new report supports the US EPA’s Lead and Copper rule and includes a charting option. Locus will continue to enhance EIM for Water by releasing the 2019 updates for the Consumer Confidence Report in January 2020.

            8. Improved Non-Analytical Views

            Locus continues to upgrade and improve the EIM user interface and user experience. The most noticeable change in 2019 was the overhaul of the Non-analytical Views pages in EIM, which support data exports for locations, samples, field readings, groundwater levels, and subsurface information. Roughly 25 separate pages were combined into one page that supports all these data views. Users are directed through a series of filter selections that culminate in a grid of results. The new page improves usability and provides one centralized place for these data reports. Locus plans to upgrade the Analytical Views in the same way in 2020.

            9. EIM search box

            To help customers find the correct EIM menu function, Locus added a search box at the top right of EIM. The search box returns any menu items that match the user’s entered search term. In 2020, Locus will expand this search box to return matching help file documents and EDD error help, as well as searches for synonyms of menu items.

            10. Historical data reporting in EDD loading

            The EIM EDD loader now has a new “View history” option for viewing previously loaded data for the locations and parameters in the EDD. This function lets users put data in the EDD holding table into proper historical context. Users can check for any unexpected increases in parameter concentrations as well as new maximum values for a given location and parameter.
