GIS – Overview
Geographic Information Systems (GIS) is a powerful tool for environmental analysis and visualization that is an essential component of Epsilon’s day-to-day business. From basic site mapping to complex spatial analyses, the GIS staff supports all of the divisions within the company, including natural resources, energy, downtown real estate, and historic permitting. GIS is used for complex cartography and data visualization, as it is adept at breaking down a complicated project or dataset into elements that are graphically readable and geographically relevant. For Epsilon’s energy clients, GIS is key for route siting and constraints analysis, where potential energy corridors or alternative project sites are explored & ranked using a number of GIS overlays. For projects where visibility is an important consideration, GIS is employed to assess visual impact, through the use of viewshed models, line-of-sight profiles, and 3-D renderings. Epsilon’s GIS team researches documents and maps for historic resource analysis, to determine historic waterlines for Chapter 91 filings or to query existing National Register listed structures within a study area. Epsilon also provides data conversion and database services. Large field-generated GPS (Global Positioning System) datasets, AutoCAD drawings, and other geographically-linked data can be converted to GIS format with proper attributing & referencing, and can be displayed over current aerial photography or other GIS layers. The GIS specialists at Epsilon have facility in working with data of all types and quality, and have extensive background not only in technical aspects of geographic information, but in the science, permitting, and regulatory aspects associated with these projects.
