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


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.

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.

In ArcMap, the features in TOWNSFROMLU were brought combined based on the TILE_NAME field, using DISSOLVE.
Process_Date: 200609

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.
