A method of correlating satellite position data with terrestrial features may include the steps of: Defining a two-dimensional grid comprising a plurality of grid points at defined locations; rounding the satellite position data to the nearest grid point of the defined two-dimensional grid to create an amplitude data table, each rounded satellite position data point in the amplitude data table defining a reference grid point value; matching the terrestrial survey data to at least four adjacent grid points of the defined two-dimensional grid to create a terrestrial coordinate table; merging the amplitude data table and the terrestrial coordinate table based on the reference grid point values to form a merged table; searching the merged table to identify the grid point with the minimum distance between an (x,y) location and an (rx, ry) location; and snapping the (x,y) location to a snapping point.
