This service contains all FCPA-maintained GIS layers that are relevant for public use. There are additional GIS datasets that FCPA maintains that are not included due to their unique business purpose for FCPA. There are also individual fields within some of these datasets that are not available to the public, so have been intentionally turned off. The data has been categorized by theme, and this categorization is standard across GEM, Jade, and Data Loader, with layer additions/removals as appropriate. Most unique features in each dataset are digitized using Fairfax County aerial imagery while some are captured in the field with differentially corrected GNSS units.
