Generating new insight by overlaying several layers of spatial information, one on top of the other, constitutes one of the main concepts of spatial data analysis, as we have already seen in the previous chapters. So far, however, we have only used operations involving either rasters alone or vector layers alone, but not a combination of both. Although the two types of spatial layers have their characteristic uses (such as rasters for DEMs and vector layers for administrative borders), combining them in a single analysis is often desired. As we shall see, this is a less straightforward task, characterized by specific procedures and decisions.

In this chapter, we are going to explore the interplay ...
