The above sampling demonstrates that it is possible to cut up an image based on
controlled vector data and analyze each section with some degree of success. The
aim of this sampling was not to show absolute values for each land type, it was
only to prove the theory that when given correct vector data representing small
area polygons then valuable data can be further derived based on spectral. Of
further advantage of anyone using the suggested algorithm is that for this type of
land cover (peri-urban and rural but close to settlements –which covers most of
the country) the controlled vector data has changed little over time and means the
process also lends itself to studies looking at change over time.
