Dutchess County uses Environmental Systems Research Institute (ESRI) products to produce and store GIS data.   GIS software is required to view our data that we provide in ArcGIS 10.8.1 File Geodatabase format, we do not export data to shapefiles due to their inherent data limitations.   All of our data is stored with the following:  

Projected Coordinate System: State Plane, NY East Zone, FIPS 3101 Feet

Datum: North American Datum 1983

Geographic Coordinate System: GCS North American 1983
