The data sets were acquired from USGS by the US Forest Service. 2. The files were processed to ARC/INFO GRIDs, merged into zones and projected to SAA Albers using a default cellsize. All processing was performed by Don Norris, US Forest Service in Columbia, SC. 3. The shaded relief grid was performed in ARC/INFO GRID with the HILLSHADE function. ---------------------------------------------------------------- ---------------------------------------------------------------- Entity/Attribute Information Entity: TOP*_30M.VAT Definition: 30 meter cells for elevation values Attributes: VALUE - elevation (MSL) in meters Entity: Definition: Attributes: Entity: Definition: Attributes: ---------------------------------------------------------------- ---------------------------------------------------------------- Status Information Data Set Status: Available Release Date: 3/21/96 ---------------------------------------------------------------- ---------------------------------------------------------------- Metadata Reference Information Date: 3/20/96 Review Date: Contact: Karl A.
