A project on topographic maps interpretation is beingdriven at I.G.N. (Institut Géographique National, France).The aim of this project is to provide a totally automatic interpretationwith a call to operator on the only suspiciouscases detected by the program. This paper presents an automaticsystem for the creation of a Digital Terrain Model(DTM) out of a scanned map.Our proposed method is based on the use of external elevationinformation and on a combined local/global strategyfor quoting the portions of curve present on the map. To reducethe combinatory of the problem, and to accelerate theconvergence, all the "trivial cases" of interruption are pretreated.After having quoted the portions of curve, a DTMis created by a classical interpolation method. |
