ORDATA is a U.S. government database of landmines and other unexploded ordnance, developed to assist humanitarian demining work. The original version of ORDATA released in 1997 was CD-ROM based, and incorporated material from the earlier Minefacts program. The most recent version, ORDATA 2.0, is distributed on a CD-ROM, as well as being available on the World Wide Web. It is hosted on the Mine Action Information Center website of the James Madison University.
