Descriptive nameHillshaded Relief Image from LiDAR and NED 10m - Grayscale
File nameimld1hpb
Spatial domainPima County
AbstractPima County Grayscale Hillshaded Relief Image generated from a composite of the following sources in the order listed:

1. PAG 2008 orthophoto project LiDAR where available
2. PAG 2005 orthophoto project LiDAR where available
3. National Elevation Data (NED) 10m cell data

The image has 10 foot pixel resolution.

A color version, imld1hpc, is also available.

Hillshade is a mosaic dataset using the hillshade function on a DEM. The DEM was created from the terrain model: terrain08 in the elev gdb on lightyear. terrain08 is made up of lidar05be, lidar08be, dempts, pinalpts. DEM is created from terrain model and stored on \\sparcgis1\arcgisraster\DEM\DEM.gdb. Hillshade is mosaic dataset located on \\sparcgis1\arcgisraster\Hillshade\Hillshade.gdb
Known errors/qualificationsAreas based on LiDAR show more detail and look better than areas based on NED data due to the higher density of LiDAR source data points.

Date of elevation data varies with the source used.
