This filegeodatabase was built
from source materials at
NASA.
This 1,997,982,182-byte file unzips into a filegeodatabase directory that can be read by ESRI and other software.
It contains bare-earth and first-return DEMs with corresponding shaded-relief images.
The first-return (ff) DEM contains no-data holes, and the shaded-relief contains holes that
are one cell larger. Pyramid files for shaded relief were created with bilinear resampling.
The coordinate system is Washington State North NAD83 (FIPS 4601). Cellsize is six feet.
