GIS Layers
Interactive Zoning Map & Digital Zoning Code
Layer catalog
The proposed catalog covers zoning, environmental, land-use, transportation, political, and infrastructure layers. Layers marked “On demo map” change the interactive map. The downloads below are the sample open-data files for this prototype. None of this is official ABC County GIS.
A production exchange would use County-approved ArcGIS services. These files are the demonstration equivalent: parcel polygons as GeoJSON, and cases and districts as CSV. Owner names are omitted.
