Abstract

In this work, we propose a set of algorithms to manage the resolution of DEM for simulation processes. First, we present an application to handle the huge quantity of data contained in DEM for real-time rendering by discriminating the less significant elevation data. On the other hand, as a second step of the process, we extend the algorithm to increase the spatial resolution of DEM for cases when it is needed. Finally, we introduce a method for increasing spectral resolution of DEM by using a skeletonization process. The algorithms were developed to be used with raster data sets, although similar considerations can be taken for vector data sets.
