Service Description: This is the updated New World Systems Aerial Overlay Basemap for use within the E911 system. It contains all of the normal aerial overlay information as the normal County version but includes the hydrants for all 3 localities. Due to limitations within NW, the overlay and underlying aerial imagery (2022) are combined into one basemap.
