There are 20 classes of secondary agricultural landuse for both dominant
and secondary landuse. This data input was created simply by converting
the polygons into a grid using ArcView. There are a greater number of No
information or No Data cells compared to those of dominant agricultural
landuse as sometimes there is no obvious secondary agricultural landuse
or the information simply isn't available.
