【Abstract】 Aceording to features of data structure of GIS for long distance transmission pipeline, spatial positioning method of pipeline is introduced. On the basis of this method, an algorithm for spatial distance measuring is put forward. At last, a programm algorithm for changing vector data (plane domain) into raster data is presented.更多还原
