Reverse Geocoding: Given latitude & longitude coordinates, what is the nearest address?

3. Reverse Geocoding: Given latitude & longitude coordinates, what is the nearest address?

Reverse Geocoding is often used in IoT (Internet of Things) applications and in dispatching applications where you have latitude/longitude coordinates and need to know the address or what is around the coordinates. Besides finding the closest address (and the distance to it), boundary information is available. Examples are county, Census Block, and Census Tract. With additional licensing, neighborhoods (e.g. Easy Village, SoHo, Hudson Yards) are available.

If you have APN (Assessor’s Parcel Numbers), there is a Reverse APN Lookup Service. This service returns address, Census and coordinate information. Separate from this service, the raw data can be licensed.
