Local Government Enterprise GIS
Es² has been the GIS consultant for West Baton Rouge Parish since 2013. Es² has assisted the Parish with the move from a fragmented, departmental and desktop-based GIS solution to a more coordinated and centralized Enterprise GIS solution. This solution has allowed the departments within the West Baton Rouge Parish Government to more efficiently and effectively manage and share GIS data internally and externally. Es² utilized the suite of Esri ArcGIS products and solutions during the development of the Enterprise GIS. Es² assisted with the acquisition of a Small Municipal and County Government Enterprise License Agreement (ELA) with Esri, which allowed for licenses for all desktop, server, and online software needed in the Parish. Es² setup and configured an Amazon cloud server to host the Parish GIS database. Es² has deployed the ArcGIS for Local Government Information Model on the cloud server, which contains a series of essential foundation layers and operational information to support a range of key maps and apps within a local government.
With a certified FAA Part 107 Remote Pilot Airman, Es² performed a topographic mapping project for the new Rose Gardens Subdivision in Baton Rouge. Es² utilized its DJI Phantom 4 Pro UAS to acquire high-resolution aerial photography of the project site. Prior to aerial photography acquisition, Es² distributed aerial targets across the project site and obtained their precise location using survey-grade Real Time Kinematic GPS equipment. A double-grid pattern at an altitude of 180 feet was programmed into the UAS flight management application, which allows for autonomous flight control. A total of 1,117 images were acquired during the flights. The individual images were processed using photogrammetric software to develop a seamless, color balanced, ortho-photo mosaic. Additional image processing created a 3D Digital Surface Model, a 3D Digital Terrain Model, and contour lines. Once the image processing was complete, an accuracy assessment was performed on the elevation model. Seventeen (17) check points throughout the site were obtained using RTK GPS. Elevations from the check points were compared to the elevation model. It was found that the accuracy of the elevation model was 0.10 feet (1 standard deviation). This project demonstrates the highly detailed and accurate mapping that can be produced from aerial photography obtained from a UAS.
Land Loss / Habitat Mapping and Analysis
Es² performed expert witness services on behalf of the plaintiffs in the Katrina Canal Breaches Consolidated Litigation. The primary service performed by Es² personnel was the development of the expert report, and subsequent testimony, titled Impact of the Mississippi River Gulf Outlet: Geology and Geomorphology. This report provided a quantitative, as well as qualitative, analysis of the direct and indirect impacts of the construction, operation, and maintenance of the MRGO channel on the Central Wetlands region east of New Orleans, Louisiana. Es² utilized historical aerial photography, maps, charts, and geologic studies to demonstrate the impacts from the 1965 to 2005. In addition to the preparation of the expert report, Es² personnel were actively involved in the development of legal strategies, review of defense expert reports, as well as courtroom presentations and exhibits. During the month-long bench trial held in the U.S. Eastern District Court in New Orleans, Es² also performed live GIS services for direct witness testimony and cross examination.
Es² collected sanitary sewer utility data for the Town of Addis to integrate into the West Baton Rouge Parish enterprise GIS system. Utilizing survey-grade GPS equipment, Es² collected data from approximately 1,000 sanitary sewer manholes and grinders. All data collected, including photographs, was stored in a Esri Local Government Information Model geodatabase. In addition to data for each manhole, information was also collected for each pipe connected to the manhole, including pipe size, invert elevation, and direction. Once all of the data was QA/QC'd, a pipeline network was created in the geodatabase. The geodatabase was published as a web service and added as an item in the West Baton Rouge Parish GIS system.
Historical Aerial Photography Analysis
This figure portrays a 15-date time-series of historical aerial photography of an area from 1936 to 1998.
Es² has extensive experience locating, obtaining, scanning, geo-referencing, and mapping historical aerial photography, which is useful in many different types of projects: Land loss mapping Site investigations Damage assessments Boundary disputes Environmental assessments
Even though historical aerial photography provides a mapping challenge due to the wide variety of film types and photo scales utilized for each date, it is an invaluable resource for time-sensitive projects.
Onsite Facilities Mapping – Air Emissions Point Source Locations
As another example of onsite facilities mapping, this image is a portion of a map that was created to illustrate the permitted air emissions point source locations for a refinery. A current aerial photograph of the refinery was acquired and ground control points used to geo-reference the aerial photograph were obtained using a Trimble Pro-XR real-time differential GPS. Once the aerial was geo-referenced, it was used as a base map in the GIS. A point for the center of each permitted air emissions point source was placed on the photograph. UTM and latitude-longitude coordinates for each emission source derived from the GIS were listed in a table and placed on the map. For ease of visual reference, the point source identification number was also labeled for each emission source. A large format plot (36"x72") and a spreadsheet of the point source coordinates were provided to the refinery. The coordinates for the emission sources were utilized in permit applications as well as dispersion modeling. The utilization of aerial photography, GPS, and GIS provided a cost-effective solution for obtaining accurate coordinates of the permitted air emission point sources for this refinery.
