| Abstract: | Large-scale DLG data is the most important basic geographic information data in the digital city geographic information platform.For the purpose of speeding up the process of city informatization,it played an important security role.Formulating reasonable DLG data production process,precise image registration,building residential areas and vegetation elements surface quickly,and the assistant program play important roles in improving data quality.The article made detailed discussion and practice about the above problems. |
