| Abstract: | Aimed the updating of GIS data, this paper has analyzed the precision source from updating DLG with digital orthographic vectorization maps, which based on the national standard of DOM precision, and partial of no-change elements between DLG and DOM. Moreover, it has estimated the precision of the renewed production. The practice proves that the result is reasonable and feasible. |
