Geographic Information Systems (GIS)
The use of a Geographic Information System (GIS) in the decision-making process by government agencies and the private sector is on the rise. In addition to rapid production of high-quality maps and graphics, GIS can be used to analyze, model, and display spatially explicit data. EEC has provided GIS services to many of our clients for a wide variety of projects using various spatial applications.
Service Areas Include:
- Network Analysis
- Spatial Computations
- Decision Support
- Visual Display
- Land Use Planning
Project Experience:
Programmatic EA for Airborne Electro-Optical Sensor, Nationwide Testing
EEC used GIS in the preparation of Environmental Assessments at several locations to delineate the Regions of Influence for electronic aviation testing. Through accurate location of affected areas, potential problems were avoided and permitting was streamlined.
White Tanks Area Drainage Master Plan Update, Maricopa County, Arizona
In a major update of a regional hydrology model, the GIS was instrumental in calculating areas of newly created basins for model inputs. Using model outputs, EEC revised GIS data to accurately reflect altered drainage patterns. New maps provided government agencies and other interested parties with updated stormwater-flow patterns.
Navajo Nation Alternative Redistricting Plan, Arizona
EEC used GIS to obtain voter preference data and census demographic characteristics. EEC assembled a voting district database for the Navajo Nation and assisted in the analysis of the State of Arizona Redistricting Plan for use in federal and state court challenges.
Craycroft Road Improvements, Tucson, Arizona
EEC used GIS for the Environmental Assessment and Mitigation Report to define different areas of vegetation cover within the project area. Accurate calculations of each habitat type were important in determining impacts involved with disturbing native vegetation.
Gila Bend Area Drainage Master Plan, Maricopa County, Arizona
EEC used GIS as a component of this drainage analysis to quickly determine housing and property values of several areas facing condemnation within modified floodplain boundaries. The ability of the GIS to locate economic property data within specific areas simplified and streamlined these calculations.
Huachuca/Cienega Creek Water Umbel Surveys, Arizona
EEC's GIS department assisted with the surveying of eight specified areas within Cienega Creek Preserve and four specified areas within Bingham Cienega Preserve that were determined to be most likely to provide suitable conditions for Huachuca water umbel. EEC prepared a report and used GIS to prepare exhibits and graphics.
