in two coordinate systems, UTM 10 and UTM 11, depending on the
project. The projects cover sections of the John
River, Lower and Upper Okanogan
River and Lake Roosevelt.
The DEM grid cell size is 1 meter. The elevation units
are in meters. Data is in Universal Transverse Mercator
Zone 10/11, in the NAD83/NAVD88 datum

The raster data is available in either USGS quarter
and as a Mosaic. The elevation data in quarter quads
is in the ArcInterchange .e00 format. The
hillshade images in quarter quad are in georeference TIFF
The point data is available in
ASCII text format. Point data is only
available by tile. For this project the tiles are 1/64
a USGS 7.5" Quad. For details on the subdivisions of

As we approve data from the contractor they
are posted here. Areas within many of the bare-earth DEMs can
be improved by further processing of the all-return point data
to better isolate bare-earth points. As we make these improvements
we will upgrade the bare-earth DEMs and derivative images posted
