  Alexandria Digital Library      

The Alexandria Digital Library (ADL) offers easy access to its collections of geographically referenced materials. The library, headquartered at the University of California at Santa Barbara, is hosted by the Davidson Library's Map & Imagery Lab (MIL). The MIL team is working with development teams throughout the world to establish remote, independent, yet federated ADL nodes featuring local geographically referenced collections.

We've recently added the following new collections to ADL.

NGDA Archive - National DOQQ Collection (follow this link and click Start Search)
Digital Orthophoto Quadrangles combine the image characteristics of a photograph with the geometric qualities of a map. DOQ's serve a variety of purposes, from interim maps to field references for earth science investigations and analysis. The DOQ is useful as a layer of a geographic information system and as a tool for revision of digital line graphs and topographic maps. These DOQ's have been made available through the California Spatial Information Library URL:http://gis.ca.gov. They have been reformatted into GeoTIFF format, with a metadata an FGDC compliant metadata entry in the description tag.



Sylvester Late 20th Century Geology Slides (follow this link and click Start Search)
This collection was produced by Dr. Arthur G. Sylvester, Professor Emeritus of Geology at the University of California at Santa Barbara. It is used for undergraduate through professional level instruction, covering the full suite of themes within geology. Particular emphasis is on late 20th century southern California earthquakes, structural geology, geology of California, and general geology.


Maya area archeological sites in Mexico, Guatemala, and Belize   Maya Forest Collection (follow this link and click Start Search)
This is a digital satellite image of the Maya Forest region of Mexico, Guatemala, and Belize from the Maya Forest Collection. The image has been visually enhanced to make it easier to differentiate between land covers and resampled to a resolution of 200 meters. It is intended for use as background imagery for vector data layers. For more information on the project, see UCSB Maya Forest GIS.
