AGRC has been working with county addressing authorities and GIS staff to develop a statewide address point dataset. We are now using address points as the primary means of locating an address, with the location along a street segment as an alternate means. Address points can provide a more accurate location than a geolocated point along a street segment. This is particularly important for quickly dispatching public safety response to a home, business or other location.
We have developed what we believe are best practices for address points:
- Each inhabited structure (residence or business) should have a point.
- Each point should have a unique address, either from a unique house number or a unique unit number. If a garage or out building is assigned a point, the address should be different from that of the primary structure. (Figure 1)
- Points should be located at the structure. For multi-unit residences or multiple office suites, all the points for units accessed from each outside entrance should be located on or near each other. (Figures 2 & 3)
- A vacant parcel may have a point if it has a unique address.
- The address for a point should be derived from the primary street name. Additional points can also exist that are derived from alternate street names.
