ACCOMPLISHMENTS
- The firm has produced off-the-shelf precision 3D terrain and building data for over 50 cities world-wide. Twelve U.S. cities were recently added to the collection, including: San Francisco; Los Angeles; Austin; San Antonio; Dallas; Salt Lake City; and the Arlington and Rosslyn suburbs of Washington D.C. Nine cities were also added to Vexcel's international off-the-shelf database, including: Sao Paulo, Rio, Vitoria, Brazil; Buenos Aires, Argentina; Stockholm, Sweden; and the Canadian cities of London, Victoria, Edmonton, Saskatoon, as well as additional areas of Toronto.
- These data sets are designed to assist broadband wireless communication service providers in planning and implementing new wireless networks, expanding existing networks, locating base stations, and providing full network maintenance. Many of these data sets also contain individual street addresses, building and real estate information, as well as, demographic information about businesses, such as size and annual revenue, for assessing customer sales potential.

GOVERNMENT/SCIENCE
APPLICATIONS
-
The firm has completed its Apex Ground StationTM for EOS. The turnkey system is specially designed for direct reception and processing of data from NASA's Terra satellite and follow-on missions. Terra was successfully launched on December 18, 1999, and is the "flagship" to NASA's Earth Observation System (EOS) series of satellites.
- The firm was awarded a contract from NASA to provide close range photogrammetry technology for use on the International Space Station. Close range photogrammetry is used for deriving accurate measurements from digital imagery. NASA intends to use Vexcel’s close range photogrammetry software, commercially available as FotoGTM, to extract measurements from digital images for a variety of projects on board the station.
