Frequently-asked questions:

What does this data set describe?

Title:
Digital Orthoimage of the 30 x 30 Minute Tile N41W1111, Idaho Generated from SPOT Satellite Imagery

Abstract: 
The USA Select product is a statewide panchromatic tonal balanced, 30-minute x 30-minute SPOTView product designed to be load-n-go into GIS and image processing systems. The source imagery is SPOT PAN 2.5-meter data. The most current imagery was preferred. Fall/Winter/Spring (leaf-off) scenes were preferred, but summer (leaf-on) imagery was used if scene gaps were present.

The Idaho Department of Adminstration coordinated the purchase of these data among numerous entities in Idaho in 2004.
