Abstract:
1. A computer implemented method for digital mapping of one or more routes, comprising the steps of: repeatedly surveying one or more routes to be recorded with one or more vehicles which traverse the routes, and which are equipped with a position finding system, said repeatedly surveying producing recorded measured values for said one or more routes for each survey; superimposing, using a computer, the recorded measured values obtained from said repeatedly surveying step, said superimposing step forming a plurality of superimposed measured values; projecting, using a computer, at least a portion of the superimposed measured values onto a plurality of planes which are associated with said superimposed measured values, said projecting step shifting at least some of said portion of the superimposed measured values to one of said plurality of planes and producing projected measured values on each of said planes; averaging, using a computer, said projected measured values to identify a single node on each of said plurality of planes which is an average of said projected measured values on each of said planes; and identifying a mapped route which passes through each single node on each of said plurality of planes.
