Claim:
1. A computer implemented method for calculating tolerance zones for utility assets, the method comprising: receiving data about a point, a line, or an area related to a location of a utility asset in a region; receiving information about said utility asset in the region from one or more databases, wherein the received information includes a type of the utility asset, a location of the utility asset, an accuracy of the location of the utility asset, accuracy requirements for the utility asset, accuracy requirements for the region, and a map tile accuracy; calculating a tolerance zone for said utility asset in the region based on the accuracy requirements for the utility asset and the map tile accuracy; and transmitting the tolerance zone to a remote device, wherein the tolerance zone is calculated from an aggregate accuracy (GPVA) and a map visual accuracy mean (MVAM) as follows: where MTa1 represents an associated map tile accuracy value for a visible map tile, and GPSa1 represents an associated GPS point accuracy value for a visible GPS point; and where (GPVA1, GPVA2, . . . GPVAN) are a set of GIPS point visual accuracy values for a visible map, and N is the number of GPS points.
