National groundwater maps highlight Texas drought

 

 

The following NASA press release discusses the most recent  national groundwater map from the GRACE satellite, showing the extent of groundwater depletion due to drought in Texas.

 

(Eurekalert.org) The record-breaking drought in Texas that has fueled wildfires, decimated crops and forced cattle sales has also reduced levels of groundwater in much of the state to the lowest levels seen in more than 60 years, according to new national maps produced by NASA and distributed by the National Drought Mitigation Center at the University of Nebraska-Lincoln.

The latest groundwater map, released on Nov. 29, shows large patches of maroon over eastern Texas, indicating severely depressed groundwater levels. The maps, generated weekly by NASA’s Goddard Space Flight Center in Greenbelt, Md., are publicly available on the Drought Center’s website.

ASTER Global DEM (GDEM) Version 2 Released

Version 2 of the free global topography dataset, ASTER GDEM, has recently been released. This version adds an additional 260,000 stereo-pair images and features improved spatial resolution, increased horizontal and vertical accuracy and more realistic coverage of water bodies as small as 1 kilometer in diameter. The DEM points are collected at a resolution of 30 meters.   The ASTER GDEM is available at no cost online from https://lpdaac.usgs.gov/

National Biological Information Infrastructure to be terminated

The National Biological Information Infrastructure (NBII) is slated for termination as of Jan 15, 2012 due to a $3.8 million budget cut.  This will include shutdown of the NBII website and any applications residing on the nbii.gov domain.

The NBII provided a program for access to data and information related to the nation’s biological resources and led several geospatial efforts including the FGDC Biological Data Profile for Geospatial Metadata,  and the Geospatial Interoperability Framework.

More information on the termination can be found at the NBII termination web page.
