Over the past several years, medium and high resolution imagery has become available from a variety of sources, all of which are important sources for the public community. Below are some of the sources that we leverage to provide the most detailed analysis for your projects.
United States Geological Survey and other domestic sources of aerial imagery of the United States provide high resolution coverage of some facilities in the United States, which are of both intrinsic interest and a useful basis for comparison with facilities in other countries.
Medium resolution imagery from satellite systems such as SPOT, LANDSAT and IRS-1C/D, with global coverage at resolutions ranging from 5 to 15 meters, remains useful for determining the overall layout of very large facilities and determining the exact location of imprecisely located facilities.
Declassified CORONA satellite imagery, with resolution as good as two meters covering the period through late 1972, provides important historical context for older facilities, and is useful for negation and change extraction in campaigns targeted on facilities constructed since 1972. Declassified U-2 aerial imagery from the late 1950s through the early 1970s provides more restricted geographical coverage than CORONA, though with significantly superior resolution.
Russian satellite imagery, initially with a resolution of two meters and with one meter coverage by mid-2000 can provide extremely useful coverage of selected targets in the late 1980s and early 1990s. Some of this imagery is available through the TerraServer website, and this older imagery has proven extremely useful for change extraction in comparison with newer commercial imagery.
Space Imaging’s IKONOS satellite began commercial operations in January 2000. Customer requests for new imagery require a minimum order of about $3,000 for a scene outside the United States. ImageSat International Space [a joint venture of Israeli and American companies] began commercial operations in January 2001, and offers a product similar to that of Space Imaging.
Other sources of new commercial satellite imagery may emerge before the end of 2001, with planned launches by EarthWatch and Orbital Sciences Corporation The projected launch dates of these satellites have demonstrated persistent delays, suggesting that one [or perhaps all] of these companies will eventually decline to enter this market in competition with SpaceImaging.
