Chapter 6: One Call Center
The land base and database use latitude/longitude (Lat/Long) coordinates.
The land base and database can produce Lat/Long information based upon street address, street/road name, intersection, milepost marker, etc. It also is possible to determine the street address, street/road name, intersection, or milepost based upon Lat/Long information. The translation of Lat/Long information is automatic. A map point (i.e., a rural area not in the immediate vicinity of a road or known map landmark) can be identified by Lat/Long information. The 811 centers in these states follow this practice: Ohio, South Dakota, New Jersey, Missouri, and Tennessee.
