Classify and explain spatial analysis functions (measurements, classification, overlay, neighbourhood and connectivity) in a raster and vector environment (level 1 and 2).
Various forms of topological relationships between spatial objects were discussed in Topology. These relationships can be useful to select features as well. The steps to be carried out are:
select one or more features as the selection objects; and
apply a chosen spatial relationship function to determine the selected features that have that relationship with the selection objects.
