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.
NOAA climate change interactive tool for U.S.Tuesday, February 14th, 2012Check out @USNOAAGOV’s interactive tool showing over a hundred years of U.S. Climate and big recent warming trends. These data are primarily intended for the study of climate variability and change.
Drought mapping using measurements obtained from weather and research satellitesMonday, February 13th, 2012The 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, 2012Recently 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. GeoEye publishes images of the Sahara Desert, Eastern AlgeriaFriday, February 10th, 2012In GeoEye’s gallery are numerous high resolution images of locations across the globe. The Eastern Algerian portion of the Sahara is an otherworldly place, a region of great diversity with endless stretches of sand dunes and rocky platforms that can reach more than 2,000 meters. The Tassili n’Ajjer “Plateau of the Rivers” National Park is a vast plateau in southeast Algeria at the borders of Libya, Niger, and Mali, covering 72,000 square kilometers.

Interactive Terrain Shaping for AutoCAD Civil 3D 2012 just released on Autodesk LabsThursday, February 9th, 2012Autodesk Labs has just released Interactive Terrain Shaping for AutoCAD Civil 3D 2012. This technology preview provides users with a workflow for developing grading proposals in Civil 3D 2012. Users will be able to interactively explore and create new conceptual grading plans. ~Autodesk Labs John Snow’s 1854 Cholera Map comes to life with the CartoDB platformThursday, February 9th, 2012John Snow created a map of a cholera outbreak in the district of Soho, London in 1854, which helped to convince authorities that the disease was caused by water ( in particular, it originated from one pump in Broad Street). The CartoDB platform allows you to map data and develop location aware applications very easily. This example of John Snow’s Cholera Map of London presented with CartoDB demonstrates how CartoDB can quickly combine different data types, then display them on a map. Satellite imagery in Colorado may face steep federal budget cutsWednesday, February 8th, 2012The 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.  This satellite image made available Sept. 26, 2009, by DigitalGlobe shows the suspected Iranian nuclear facility of Fordo near the holy Shiite city of Qom, where Iran is has begun enriching uranium, according to the U.N. atomic watchdog group, the International Atomic Energy Agency.
