lecture: OpenDEM Generator: combining open access Digital Elevation Models into a homogenized DEM
OpenDEM Generator is a new Free and Open Source Python tool to combine several existing Digital Elevation Models (DEM) into a unified DEM with homogeneous resolution and proper pixel alignment in a simple way.
By just using a configuration file the user is able to download the available input data and to process them subsequently. With the source code also several sample configuration files are distributed, so everyone will be able to recreate the DEM without much efforts. OpenDEM Generator uses a Python standard library to download data, while the processing part is managed by GDAL and GRASS GIS in an automated way.
OpenDEM Generator has the following capabilities:
- simple and automatic way to create the DEM output
- weighted resampling and optional interpolation to increase the resolution of input data
- automated cleanup of lacking data such as holes along the borders of adjacent datasets
Future enhancements may include the support of contour lines and/or elevation points as input where full DEMs are not yet existing.
