Precision geocoding from SAR data and the combination of SAR with other data sets

The authors outline the context and functionality of the geocoding demonstrator, and focus on critical areas of particular interest in the design and implementation of the system. They describe the software developed on a Sun Workstation for digital elevation model and map manipulation, height extraction and image merging and the user interface necessary to carry out this work. The importance of geometric rigour and the need for good validation tools are demonstrated
