| Abstract: | DLG is the main part of digital result of fundamental GIS. The rationality of evaluation and analysis of DLG accuracy is the key to its wide application in various industries. Using GPS - RTK to survey ground object points with the same name and linear ground object element in the experimented area in order to generate the fundamental data, in the light of error theory, this paper asses- ses and analyzes the accuracy of the DLG of the second investigation result combined with statistics and reaches reasonable conclusion. |
