A combined GSDI 14 and AfricaGIS 2013 conference is planned for November in Ethiopia, and a deadline for abstracts is fast approaching. The conference theme is “Spatial Enablement in Support of Economic Development and Poverty Reduction.”
A suite of real-time soil characteristic products for the contiguous United States will be enhanced by data from the upcoming Soil Moisture Active Passive (SMAP) and Global Precipitation Measurement (GPM) satellite missions. These products are used by operational weather forecasters to aid in analyzing and forecasting drought, extreme heat, and convective initiation.
Copernicus aims to produce data to be used by national and local authorities in the European Union for monitoring, modeling, forecasting and reporting. The European Space Agency is developing five new missions called Sentinels specifically for the operational needs of the Copernicus program.
By detecting various crops at early stages in the planting season and understanding how pixels evolve over the planting season, crop yield forecasts can be improved and provided earlier. This study uses the Satellite Automatic Image Mapper to classify Landsat imagery of crop fields for the 2011 and 2012 planting seasons.
In the heart of Southwest Virginia lie two technologically distinct power plants. One uses traditional coal-burning technology, and the other uses innovative “clean coal”-fired technology. With two plants within miles of one another, this project aims to use NASA Earth observations to monitor and compare the environmental impacts of each.
The Cheyenne Bottoms Wildlife Area is the largest wetland in the interior United States, and is a stopover for 45 percent of the birds who migrate north through the area. A land cover classification map and an estimate of suspended sediment changes will help managers to track the effectiveness of policies aimed at maintaining this critical habitat.
Tropospheric ozone is harmful to humans, trees, crops, and other vegetation. This project focused on providing the U.S. Forest Service with a sustainable tool to enhance its current ozone monitoring practices using NASA remote-sensing data. Data from the Ozone Monitoring Instrument and the Microwave Limb Sounder aboard the Aura mission were used for this project.
Hydrological modeling has the potential to drastically improve water resource management in Yosemite National Park. By combining satellite-derived data, such as precipitation, temperature, land cover and elevation values, it is possible to ascertain and quantify surface water availability at any given time.
Using pre- and post-attack Landsat imagery, 7.2-meter validation plot data, and various modeling strategies, forest stand changes were measured in a subalpine ecosystem at Fraser Experimental Forest in Fraser, Colorado, which resulted from the mountain pine beetle epidemic from 1996 to 2002. This new information will aid local forest management stakeholders and decision-makers, spur ongoing restoration efforts, and assist future research projects.
A team of NASA DEVELOP interns at Langley Research Center used satellite data along with the U.S. Federal Emergency Management Agency’s HAZUS flood model to examine the destruction caused by extreme rainfall events in Duluth, Minnesota, and Thunder Bay, Ontario.
