In ArcMap, towns within our study area were selected from LANDUSE and a new layer was created from this selection.
Towns were selected by attribute, based on their Town_ID code. The following Town_IDs were selected: 9, 30, 31, 38, 48, 71, 92, 105, 116, 119, 144, 164, 184, 205, 206, 210, 213, 229, 246, 254, 295, 320, 298, 324, 342, and 347. The selected features were then exported as a new layer, TOWNSFROMLU.

The dissolved land use layer, which now shows town boundaries, was imported into Idrisi Kiliminjaro as a vector file. The .vdc file was edited to assign the names of each town to the proper polygon.
