Geospatial analysis uses geographic information systems (GIS) technology to illuminate and solve complex environmental problems. GIS technology merges and analyzes spatial data and information from multiple sources to create new perspectives on natural resource landscapes. Versar has been a provider of geospatial services for two decades and has completed more than 3,000 private and federal GIS projects across the globe. Versar is an Environmental Systems Research Institute (ESRI) Authorized Business Partner/Reseller. We are also on the forefront of GIS technology advancements, which enables us to provide clients with advanced solutions from a variety of vendors.
Versar has applied geospatial analysis to:
- Identify and quantify the extent of impacts
- Locate probable contaminant sources or hot spots
- Rank potential restoration or mitigation sites
- Model habitats, impacts, and natural ecological phenomena
Versar GIS services support survey designs; baseline studies; natural resource damage assessments; environmental impact studies; biological assessments; integrated natural resource management plans; integrated cultural resource plans; fire management plans; wildland fire risk assessments; watershed planning; airfield services; and infrastructure or facilities siting.
Our recent projects include use of GIS for development of a clear zone management plan and environmental assessment for Chambers Field, Fentress, and Oceana Airfields, Virginia. Versar performed GIS analysis to find obstructions penetrating the airfields' imaginary surfaces. We also used GIS for sampling design for the Chesapeake Bay Long Term Benthic Monitoring Program (LTB). For this project, Versar specialists applied GIS tools to develop and implement statistically robust spatial sampling designs. For this annual program, we randomly choose 180 sample points distributed over six strata that accurately characterize the condition of the Bay and support water quality standards. Versar's other projects have included systematic, random, or hybrid point selection methodologies for field studies ranging in scale from a few hundred square meters to whole regions.
We apply our GIS expertise in all aspects of our business from cultural resources to airfield obstruction analysis; conservation buffering; fire management plans; and emergency preparedness analysis. For cultural resource projects, we developed a series of predictive models at Avon Park Air Force Range (AFR), Florida for four temporally distinct archaeological site types across Polk and Highland Counties, Florida. The model included a review of known site distributions and determined normalized site densities for environmental variables including elevation, proximity to water, soil order, and soil drainage.
