Released by an international team of scientists is a laser-radar image of the area surrounding the site of a Magnitude 7.2 earthquake that occurred in Mexicali, Mexico, in 2010. The laser radar technique can spot surface changes of just a few centimetres; in this image the blue represents a post-quake reduction in height and red indicates an increase.

The National Oceanic and Atmospheric Administration’s (NOAA) Center for Climate Prediction holds a monthly drought briefing by teleconference to identify the latest drought areas in North America, according to Don Comis of the USDA Agricultural Research Service (ARS). ARS scientists, Martha Anderson and Bill Kustas, are hoping that in a year or so, data from their computer model/satellite package will give evapotranspiration (ET) maps a seat at that briefing.
ASPRS Board votes unanimously for immediate funding to continue national moderate resolution imaging programMonday, February 13th, 2012
Recently the American Society for Photogrammetry and Remote Sensing (ASPRS) Board of Directors voted unanimously for a third resolution calling for immediate support and funding for the continuation of the Nation’s moderate resolution imaging program. Several events have led to the possible discontinuation of the collection of moderate resolution, multispectral remote sensing. One of those events was the technical failure in the Enhanced Thematic Mapper Plus (ETM+) instrument on-board the Landsat 7 spacecraft in May 2003, and most recently the decline of the Landsat 5 spacecraft.
Although many other remote sensing efforts exist these days, the more than 40 years of uninterrupted Landsat imagery has been instrumental in monitoring ongoing stresses on the Earth from climate change, population, land use and other factors that challenge the natural resources available to mankind. According to the announcement, measuring the Earth’s resources such as food, water, and energy is best done by collecting and implementing moderate resolution imagery.
The Denver area has become a center of satellite imagery providers in recent years. Proposed steep cuts in the U.S. Department of Defense budget could affect satellite-imagery providers DigitalGlobe, headquartered in Longmont, and GeoEye,based in Virginia with a processing and operations center in Thornton. Combined, the companies have about 1,200 employees.
