Orthoimage Product Characterization Test

American Society for Photogrammetry and Remote Sensing Annual Meeting,

Denver, Colorado

26 May 2004

What?

An analysis of an orthoimage product compiled from imagery collected with a digital sensor

Where?

The John C. Stennis Space Center in southern Mississippi

Why?

To provide an objective evaluation of the orthoimagery produced by a given sensor and operator.

The USGS will compare the results to its specifications for orthoimagery at the same ground sample distance and will consider utilizing that sensor for future work if the product meets or exceeds specifications.

Who?

The USGS Priority for testing:1. Cartographic Services Contract primary

contractors and approved sub-contractors

2. Contractors procuring 133 Urban Area orthoimagery for the National Geospatial-intelligence Agency

3. Other sensor operators

When?

Image collection requires good weather and advance scheduling in adherence to the “Remote Sensing Characterization Project Digital Camera Product Characterization In Situ Test Plan for Aircraft Flyover at NASA Stennis Space Center” (a.k.a. Test Plan)
