1. A process for generating a land survey map comprising the steps of:

  • generating digital image data corresponding to an aerial view of a geographic survey region;

    rectifying the digital image data with a processing unit to create a corrected planimetric image base map of the geographic survey region;

    storing the image base map in an image base map database;

    generating a legal description map for at least one parcel of land within the geographic survey region with the processing unit, wherein the legal description map includes property line data corresponding to property lines associated with the parcel of land;

    storing the legal description map in a legal description map database;

    generating position data for at least three survey points with a ground-based remote sensing unit; and

    using the processing unit to retrieve the legal description map from and legal description map database and overlay the legal description map onto a portion of the image base map retrieved from the image base map database to generate a comprehensive survey map for the parcel of land, based on the position data of the survey points generated by the ground-based remote sensing unit.
