| Abstract: | Digital Elevation Model(DEM),describing the earth's surface fluctuation,is an important product of fundamental geographic information.Currently,the achievements of DEM research are very plentiful.With the emergence of new spatial altimetry technology,the accuracy and density of original data collection is improved constantly,which directly affects the DOM quality.During the DOM production process,how to control the DEM quality as well as improve work efficiency is becoming a great challenge. |
