Making Method of the 1∶10000 Scale Topographic Map Based on ArcGIS and Google Earth
Aiming at the low efficiency of 1∶10 000 Scale topographic maps,this paper proposes the method of combining Google Earth and ArcGIS to make 1∶10 000 Scale topographic maps.Studies the process and method of Google Earth and ArcGIS to make Scale topographic maps,and analyzes the existing errors and mapping accuracy.Suzhou institute,for example the 1∶10 000 Scale of topographic map production,research shows that free use Google Earth to obtain high precision satellite images,by ArcGIS registration,vector quantization and generating contours steps make a 1∶10 000 Scale topographic map can completely meet the accuracy requirements,and than the traditional large scale mapping method reduces the production cost,at the same time greatly improve the efficiency of drawing.The vectorization of topographic map should be operated from whole to part and from thick to fine according to the level from point to line to plane.Color different layers and label them on the image.The results provide a more efficient method for 1∶10 000 Scale topographic maps.
