A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data—known as Bedmap. The product was a result of work led by the British Antarctic Survey, where researchers compiled decades worth of geophysical measurements, such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation Satellite, known as ICESat, and ice thickness data collected by Operation IceBridge.
This article focuses on a unique site selection problem for calculating the demand of a Muslim population for locating religious facilities (mosques) as an example of services that require short walking distance. Geodecision’s senior GIS Analyst Hany A. Hassaballa shares his methodology for identifying a catchment area and determining service level capacity for sites under consideration.
For decades, governments and NGOs have relied on private sector solutions to gather and interpret emergency data for crisis response, but a growing number of them have warmed in recent years to much cheaper "open-source" (OS) technology. IRIN spoke to experts around the world about their search for the most appropriate mix of technology to manage disasters.
The elevator pitch or what some prefer to call the executive pitch is at all times the complete embodiment of the project: its trigger, its concept and its payback.

Current beach closure advisories are based on precipitation and not individual beach conditions. The NASA DEVELOP team at the Jet Propulsion Laboratory examined historical Synthetic Aperture Radar (SAR) imagery of stormwater plumes from the Southern California Bight to investigate the capabilities of SAR to monitor individual stormwater plumes and relate with Enterococci concentrations, to the state water quality standard.
NASA launched the Landsat Data Continuity Mission satellite on February 11. Since then, NASA mission engineers and scientists, with USGS collaboration, have been putting the satellite through its paces – steering it into its orbit, focusing the instruments, calibrating the detectors, and collecting test images. Now fully mission-certified, the satellite will be transferred to USGS operational control and renamed Landsat 8.
At Code for America, they are gearing up for the National Day of Civic Hacking; a weekend that galvanizes its ongoing movement to call citizens to action. Code for America wants citizens everywhere to help their cities work better, through technology. Hannah Young laid out ten reasons hacking is good for cities.
As the tornados touched down in Oklahoma a few weeks ago, first responders jumped into action. In support of these brave and motivated people and organizations, DigitalGlobe tasked its satellite constellation to capture imagery of the area as part of its FirstLook service, collectingt high resolution panchromatic WorldView-1 satellite imagery as well as color GeoEye-1 imagery. Upon collection, DigitalGlobe launched it’s...
