IGWS Data and Publications

Go directly to the List of Publications.

The Survey produces and sells a large variety of maps and publications. These include educational materials, guidebooks, reports of investigations, technical reports, water supply reports, historic annual reports, and a variety of maps.

Maps from the Survey include the popular U.S. Geological Survey 7.5 minute quadrangle series (1:24,000 scale) and the county topographic map series (1:100,000 scale) of Iowa. These maps of local terrain conditions serve outdoor recreation enthusiasts as well as scientists and other professionals. Orders for these maps can be placed online. Other maps (e.g., vulnerability map, bedrock geology) and reports appear in the Survey's List of Publications and are available on request.

Aerial photographs of Iowa are available from a number of sources. The Survey does not sell aerial photos, but we can provide assistance in finding a suitable source for photos. Two full state coverages of aerial photography taken at 1:40,000 are available from the National Aerial Photography Program (NAPP). The most recent was imaged in the spring of 2002 in color infrared (CIR), while an older set was imaged in 1990, in black and white. Both of these can be viewed online at the Iowa Geographic Map Server. The 2002 CIR images can also be viewed at the Iowa DNR Interactive Mapping site.

Hardcopy prints of aerial images can be obtained from the U.S. Department of Agriculture, Aerial Photography Field Office (801-975-3503), in Salt Lake City, UT, which has NAPP photography, as well as archives of U.S. Department of Agriculture photography normally used by county Farm Services Agency or Natural Resources Conservation Service offices. The U.S. Geological Survey's EROS Data Center (605-594-6151) has several types, scales, and dates of aerial photography used for various U.S. Geological Survey projects including production of U.S. Geological Survey topographic maps. These are distributed only in digital formats. Another possible source of aerial photography is Aerial Services, Inc. of Cedar Falls (319-277-0436).

There is a wide range of satellite images of Iowa that can be obtained from various places. At this time, the Survey does not have any satellite images available for sale. High resolution satellite images are generally expensivecosting several hundred to several thousand dollars. Several kinds of imagery can be viewed at low resolution at the U. S. Geological Survey’s Glovis Viewer.
