Topography: Slope - Ipswich Watershed - Idrisi Raster File.

Summary

Short name: 

GIS_ip30_info_slope

Abstract: 

This datalayer is part of a group of layers used for research in the Ipswich River Watershed. This is slope data for the study area. Taken from the source elevation tile data which was provided on the MassGIS website www.state.ma.us/mgis/massgis.htm in ESRI-format shapefile format and imported into IDRISI software using the ShapeIdr command. The resulting vector elevation files were converted to raster format using successive Lineras macro commands. This has the effect of mosaicing the tiles as well. The raster image was filtered once using a low-pass (mean) filter, then masked to the Ipswich study area parameters (extent). We then used the DEM to produce the slope model using the SURFACE module in IDRISI.
This datalayer was produced as part of a research project concerning the Ipswich River Watershed.
