Abstract
The paper introduces much about the DEM digital progressive generalization based on new DEM theory for the diversification of demands in applications, at the same tine, gives the algorithm to realize this process. A number of data experiment results show that we should do the digital generalization to keep the DEM quality. And only the high fidelity DEM can reserve features well. From the progressive digital DEM generalization, we can do the multi-scale visualization of contour lines well. These series of research work and data results have open our minds in DEM thinking.
