Geog. Extent:	Main Hawaiian Islands

Datum:		NAD83

Description:	Georeferenced hillshade images converted to TIF format.
		
Source:		Used ArcToolBox (v9.1) to convert from GRID to TIF using
		Data Management Tools - Raster - Copy Raster.

		Hillshade GRIDs created by OP using USGS 10 meter DEMs, 
		2003.  

		Used the following Arc commands:

		GRID: OUTGRID = ingrid * 0.3048 
		{to convert from feet to meters for GRID cells in feet}

		GRID: OUTGRID = MERGE(ingrid1, ingrid2,...)  
		{to append grids to one islandwide grid}

		GRID: GRIDCLIP <in_grid> <out_grid> COVER <clip_cover>  
		{to clip the GRID file to remove blank cells}

		ARC: HILLSHADE <in_grid> <out_grid> 315 45 SHADE <0.3048>
		{used 0.3048 for GRIDs with cell values in feet}
