Individual Towns that are Fully or Partially in the Ipswich and Parker River Watersheds - Idrisi Raster File

Abstract: 

This datalayer is part of a group of layers used for research in the Ipswich River Watershed. This layer was created in July 2006 for Marine Biological Laboratory (MBL) in Woods Hole. This layer shows the boundaries for the towns in the Ipswich River Watershed and the Parker River Watershed. This data layer was created so that the town boundaries would correspond to the boundaries of the corresponding land use maps. This datalayer has complete information. Display town boundaries for the study area.

Methods: 

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 numbers from 1 to 26, replacing the previous values, which ranged from 9 to 347.
