A TerraAtlas presents aerial photos and overlays in a brochure format optimized for printing. It can be downloaded in a PDF format. A TerraAtlas looks like a map street atlas, but with imagery in the background. TerraAtlas is automatically produced, with a user choice of imagery and data layers, for any rectangular area or for a known geographical zone, e.g. a zipcode or a city. For downloading and self-printing, TerraAtlases are produced at 150 dpi (dots per inch). For publication, TerraAtlases are produced at 300 to 1200 dpi. The NASA Regional Applications Center has published a Washington TerraAtlas (ISBN 0-9764201-090000) and intends to publish TerraAtlases for all major US cities.
Example: Washington, DC, TerraAtlas, 48 pages
