Forming the geographic foundation of the NRI is the high-accuracy countywide basemap (1”=100’) also developed by Westchester County GIS from the 2000 and 2004 photogrammetric projects. Produced at a uniform grid (800’ scale/11x17 size maps), the series contains 16 GIS data layers (including wetlands, floodplain zones, steep slopes, aquifers, lakes, building footprints, and topography among others) this new planning tool combines geospatial data from authoritative county, state, and federal sources.

Each map is made available in the new GeoPDF format. Users will be prompted to installed the GeoPDF toolbar which turns Adobe Reader into a powerful geospatial application that gives users the ability to view, manipulate and update mapping data while leveraging Adobe collaboration capabilities to share information with others.
