“The public will be able to use the aerial photographs as an historical archive; locate their home, property, or favorite recreational area; and have access to more historical aerial photography than is provided by Google Earth,” said Steve Bowman, UGS Geologic Hazards Program Manager. Links to prior UGS air photo compilation publications, imagery collection sample images, and a comparison illustrating land-use changes along the Wasatch Front over time are also available. “These aerial photographs will also be very useful for professionals involved with geologic, geotechnical, and environmental assessment and investigation projects, as well as for land-use planning and other projects to document land-use, geomorphologic, geologic hazards, and other changes that may have occurred in a particular area,” stated Bowman.
Users can search for photographs using the new web application available at http://geology.utah.gov/online/aerial_photos/index.htm, and selecting the UGS Aerial Imagery Collection link at http://geology.utah.gov/databases/imagery/. The web application may be viewed using current versions of Firefox or Google Chrome browsers (Internet Explorer will not work with the application). Photographs are available as small JPEG images for previewing and direct download, and as high-resolution (600, 800, or 1200 dpi) ZIP –compressed TIFF images for direct download or transfer to a user’s portable hard drive by the Natural Resources Map & Bookstore (located at 1594 West North Temple, Salt Lake City, Utah, (801) 537-3320 or 1-888-UTAHMAP, email@example.com. An initial minimum fee of $10.00 will be charged for the first 15 minutes, with an additional $5.00 charge for every extra 15-minute segment for file transfer by the bookstore.
Most graphics software can open JPEG and TIFF images for viewing, image processing, and printing; however, specialized image software may be required to open larger images or TIFF files with ZIP compression. Current versions of Adobe Photoshop, Google Picasa, IrfanView, and Windows Photo Viewer (Windows 7) can open TIFF files with ZIP compression.
