Title
Hillshade -- 10 meter
1.2
Abstract
This is a 10 meter Hillshade file created by Metro from USGS DEM data provided by the BLM. It covers the 3-county area (Washington, Multnomah, and Clackamas Counties).
Purpose
This data is provided as both an analysis and a cartographic tool for RLIS users. The raster data can be used as a grid for spatial analysis. In addition, it can be used within ArcMap to create unique shaded relief effects.
Supplemental information
Metro downloaded the DEM tiles from the BLM website (http://www.blm.gov/or/gis/index.php), stitched the tiles together, and then reprojected the data. The BLM data is a "smoothed" version of the USGS 7.5-minute topographic quadrangle data; for more information on the BLM data see ftp://ftp.blm.gov/pub/OR/gisweb/metadata/(10meter)DigitalElevationModelCollectionOregon(Mergedinto1degreebufferedblocks).txt
