Geographic Information Systems (GIS)

Shannon & Wilson builds and manages complex GIS databases.  Our GIS experts analyze and interpret geospatial data and integrate Global Positioning System (GPS) data into GIS for a wide variety of environmental and geotechnical projects.  We present the results clearly with maps and other graphics. 

We have effectively used light detection and ranging (LIDAR) to integrate topographic data with geotechnical investigations for more accurate site characterizations. Using LIDAR data in potential landslide areas helps Shannon & Wilson provide accurate modeling of scalable contour intervals and geomorphic mapping of recent and historical activity, so our clients can take appropriate steps to mitigate landslide risk. 

Our field staff uses mobile GIS technology to collect and modify data in the field.  We use the most current version of ESRI® ArcGIS software available, as well as applicable extensions, to provide our clients with results on which they can rely.

Examples projects for which we use GIS applications to track or present data include:

  • Geologic hazard mapping
  • Contaminant plume delineations
  • Long-term groundwater modeling
  • Landfill compliance
  • Corridor studies
