A series of satellite images from NASA’s Terra satellite, which began capturing the images in 2000, has revealed the shocking decline of water levels in the Aral Sea.
/span>All students (grad, undergrad, recent graduates) interested in geospatial technology: the application for the NASA DEVELOP Program in Spring 2015 term opens this Monday, September 29th, and runs through November 7th.
The NASA DEVELOP National Program fosters an interdisciplinary research environment where applied science research projects are conducted under the guidance of NASA and partner science advisors. DEVELOP is unique in that young professionals lead research projects that focus on utilizing NASA Earth observations to address community concerns and public policy issues. With the competitive nature and growing societal role of science and technology in today’s global workplace, DEVELOP is fostering an adept corps of tomorrow’s scientists and leaders.
This is a great program, and several CNR students have been involved, and have great things to report.

Just in time for class on topography and rasters tomorrow: new high res shuttle DEM data is being released for Africa. The image above shows the Niger River Delta in 90m res, 30m res, and landsat.
From the press release: In Africa, accurate elevation (topographic) data are vital for pursuing a variety of climate-related studies that include modeling predicted wildlife habitat change; promoting public health in the form of warning systems for geography and climate-related diseases (e.g. malaria, dengue fever, Rift Valley fever); and monitoring sea level rise in critical deltas and population centers, to name just a few of many possible applications of elevation data.
On September 23, the National Aeronautics and Space Administration (NASA), the National Geospatial-Intelligence Agency (NGA), and the U.S. Geological Survey (USGS, a bureau of the U.S. Department of the Interior) released a collection of higher-resolution (more detailed) elevation datasets for Africa. The datasets were released following the President’s commitment at the United Nations to provide assistance for global efforts to combat climate change. The broad availability of more detailed elevation data across most of the African continent through the Shuttle Radar Topography Mission (SRTM) will improve baseline information that is crucial to investigating the impacts of climate change on African communities.
Enhanced elevation datasets covering remaining continents and regions will be made available within one year, with the next release of data focusing on Latin America and the Caribbean region. Until now, elevation data for the continent of Africa were freely available to the public only at 90-meter resolution. The datasets being released today and during the course of the next year resolve to 30-meters and will be used worldwide to improve environmental monitoring, climate change research, and local decision support. These SRTM-derived data, which have been extensively reviewed by relevant government agencies and deemed suitable for public release, are being made available via a user-friendly interface on USGS’s Earth Explorer website.
Nice slider comparing the 90m to the 30m data here.
/span>/span>Wundermap has a nice interface where you can add fires to your animated weather radar map. I caught this snap as our rare September storm (an atmospheric river apparently) moved over the King fire this afternoon. It radically changed the flow of the smoke plume, which shifted from northeastly to northerly. According to Scott, who talked to Rob, it was dumping up at Blodgett. So we will see what this means for the fire tomorrow.
/span>Here is a map of voting results from yesterday's historic independence vote in Scotland. Overall the Nos carried the day - 55% - 45%. Interestingly, Motherwell and Hamilton, two towns in my family's life, were split. Motherwell voted Och Aye and Hamilton voted the Noo.
