Fig. 17.1 Landcover classification workflow
For the most part, the geospatial data processing tasks in this case study will be
carried out using the vector and raster utilities fromGDAL/OGR that were explained
Part I. For some of the more advanced processing steps, such as creating a cloud free
composite and a land cover map, the GDAL/OGR command line utilities are not suf-
ficient and a number of third party utilities described in Chaps. 12 and 13 will be used.
A schematic overview of the workflow is shown in Fig. 17.1 . The utilities used for
the different processing steps are written in italic . We distinguish four main building
blocks. The first three deal with the production of the land cover map: create input
