MIL's collections of maps, aerial photography, satellite imagery and other spatial data exceed 5 million information objects. As of 1992, MIL was ranked as the number one spatial data collection in the top 100 members of the Association of Research Libraries. According to the 2006 Guide to US Map Sources, MIL is the third largest academic map collection in the country.
Aerial Photography and other remote sensing data
The imagery collection of about 4 million items is composed of 2.8 million aerial photographs and 1.2 million Landsat MSS satellite images, with the latter being world archival coverage for the time period 1972-1978. New to aerial imagery? Check out our aerial photography tools to learn how to find flights covering your area of interest and read indexes. We also have a page that describes major portions of the collection.
Air photo research is labor-intensive. Many images have been pre-scanned for your convenience, but an effective delivery mechanism has yet to be developed. However:
- Aerial Photography Tools include our AP Flights catalog, lists of frequently requested photos, and a variety of finding aids that will help you to identify photographs to help you with your work. All imagery is available for inspection here in MIL, but appointments are required for detailed research. This service is free to UCSB researchers and students. Various fees may apply to community users.
- The Aerial Imagery Research Services offers research services that allow us to do the work for you and deliver the results electronically.
- Frequently Requested Aerial Photographs
We have pre-selected various 'flights' for densely populated areas of the state that are of frequent interest. If you are a scholar doing change analysis in California or in private industry conducting Environmental Site Assessments, these lists will show a decade-by-decade snapshots of the state:
The map collection is one of the largest in the state. In addition to a comprehensive collection of materials for Santa Barbara, Ventura, and San Luis Obispo counties, we also specialize in foreign medium- and large- scale topographic maps.
The digital data collections are growing at about one terabyte per year and is composed predominantly of physical sciences datasets, satellite imagery, and digital mapping data of the United States and other Earth locations. Thousands of scanned aerial photographs are also part of this collection.
