Table 5: Additional object classes
Figure 8 shows the reference maps compiled manually with a vector based GIS software system. For
each object class a separate layer was created. The reference maps are of the same size as the optical
and SAR images. To compare the reference data with the participants’ data to pixel accuracy, each
layer of the vector-based maps was converted into a raster data layer of the same pixel size as the
original images.
