TITLE: SHADED RELIEF SURFACE

Geodataset Name:     SHDRL
Geodataset Type:     Image
Geodataset Feature:  Surface

GENERAL DESCRIPTION
This is an image of a Shaded Relief Surface. The integer values enable us to display a continuous surface of elevation, as opposed to topography which is broken into intervals. The image was created from a DEM at 30 meter cell size, and where this was not available a USGS DEM at 90 meter cell size was used.

RESOLUTION:           90 Meter
DATA SOURCE:          UNIVERSITY OF FLORIDA GEOPLAN CENTER
SCALE:                NA
GEODATASET EXTENT:    State of Florida

USER NOTES:
The cell values for this grid represent illumination value from 0 - 255. The shaded relief image was created from the a 30 meter grid when available and the USGS DEM (90 meter) where 30 meter data is not available (Panhandle, and some Central Florida counties).

Shaded relief surfaces are mainly used as background in mapping and displaying data. This image CANNOT be used for analysis since it is simply an 8 bit greyscale image.
