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 land use map of the study area was imported into Idrisi Kiliminjaro and converted to a raster file. After importing TOWNSFROMLU, the data base file was opened and the field TILE_NAME was exported to a raster image.
The map was reclassified so that the towns were assigned a value of 1 and the background was assigned a value of 0.
The map was updated to give a value of 1 to pixels in the following positions: (r: 344. c: 1017) and (r: 769, c: 1179). This value was assigned because these pixels were not classified in the conversion from vector to raster.
