Slide 5: Isolating data for a single country
The environmental and species distribution data is available as a .DBF database file for the whole of Africa. We need to isolate just a part of it in order to run the GAM on a limited training dataset.
It is imported into Arcview, and displayed as an "Event Theme"
The country data shapefile is imported to ArcView.
The study country is selected
The shapefile is used to select the relevant set of database records
The selected records are then exported as a new DBF file ("Zambia.dbf")
