METHODOLOGY OF GIS BASED ACCURATE CENTERLINE MAP DRAWING SUPPORT SYSTEM USING DIGITAL MAPS FOR STREAM AND ROAD

摘要

The present invention is a linear mapping and the river based on GIS, road axis, it is used to create for the System and method on that, the present invention automatically detects exact position, use outline data, pass through the center line in river, accurate center line can be used in various be widely applied in field by the point setting of update navigation data stream and the road center line created by existing and inaccurate method and algorithm with each and by the process that execution connects a center line in numerical map is generated by the national remote sensing and GIS-Geographic Information System development project that derives from of the donna mileage chart formation every bit of numerical map.
