On April 1, 2016, NASA's Land Processes Distributed Active Archive Center (LP DAAC) began distributing ASTER Level 1 Precision Terrain Corrected Registered At-Sensor Radiance (AST_L1T) data products over the entire globe at no charge. Global distribution of these data at no charge is a result of a policy change made by NASA and Japan.
The AST_L1T product provides a quick turn-around of consistent GIS-ready data as a multi-file product, which includes a HDF-EOS data file, full-resolution composite images (FRI) as GeoTIFFs for tasked telescopes (e.g., VNIR/SWIR and TIR ), and associated metadata files. In addition, each AST_L1T granule contains related products including low-resolution browse and, when applicable, a Quality Assurance (QA) browse and QA text report.
More than 2.95 million scenes of archived data are now available for direct download through the LP DAAC Data Pool and for search and download through NASA‘s Earthdata Search Client and also through USGS‘ GloVis , and USGS‘ EarthExplorer . New scenes will be added as they are acquired and archived.
ASTER is a partnership between NASA, Japan‘s Ministry of Economy, Trade and Industry (METI), the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, and Japan Space Systems (J-spacesystems ).

Dr. Tosha Comendant, Senior Scientist at Conservation Biology Institute, will give an introductory tour to demonstrate multiple ways to explore and create content in Data Basin. Data Basin is an online mapping and analysis platform that supports learning, research, and sustainable environmental stewardship. The tour will include examples of keyword & geographic search functions, mapping, and collaborative tools. A 30 minute presentation will be followed by 15 minutes of informal questions and discussion. Questions always welcome to: firstname.lastname@example.org

More than 14 million environmental sampling records from National Laboratory are now available onlineRead Now
LOS ALAMOS, N.M. – Regulators, stakeholders, scientists and the greater public will have access to remediation and other environmental data records associated with EM’s legacy nuclear cleanup program in near real time on a new website portal. Conversion to this cloud-based system achieved a substantial reduction in operating and maintenance costs, with changes and process improvements resulting in an estimated total cost savings of more than $15 million through 2015.
Previously contained in a dozen independent databases, the integrated records of Los Alamos National Laboratory (LANL) — part of DOE’s network of national laboratories — are now stored in one location, the website Intellus.
The system contains 14 million records, including more than 28,000 locations and about 300,000 samples. The data span a wide range of media including air, soil, sediment, biota, and water, and it includes various analytes and time periods.
The U.S. Environmental Protection Agency (EPA) has released the third edition of a report, ‘Climate Change Indicators in the United States.’ The report presents observed data on key measures of our environment, including U.S. and global temperature and precipitation, ocean heat and ocean acidity, sea level, length of growing season, and many others. With 30 indicators that include over 80 maps and graphs showing long-term trends, the report demonstrates that climate change is already affecting our environment and our society.
The third edition of the Indicators report adds additional years of data and four new indicators: Lyme disease, heating and cooling degree days, wildfires, and water level and temperature in the Great Lakes. In addition, the report adds four new features that connect observed data records to local communities and areas of interest, including cherry blossom bloom dates in Washington D.C., timing of ice breakup in two Alaskan rivers, temperature and drought in the Southwest, and land loss along the mid-Atlantic coast.
EPA compiles decades of observed data in cooperation with a range of federal government agencies, nongovernmental organizations, universities, and other institutions. The Indicators report focuses on long-term trends for key measures of our environment for which high-quality data exist. Each indicator and the report itself were peer-reviewed by independent experts, and extensive technical documentation accompanies the report.

To help communities and citizens plan for the risks of coastal flooding and other climate-change-related impacts, the Department of Homeland Security, the Department of Defense, the National Geospatial-Intelligence Agency, and the U.S. Geological Survey are releasing today a collection of non-sensitive datasets containing mapping information on hundreds of thousands of the Nation’s infrastructure units and geographical features, including bridges, roads, railroad tunnels, canals, and river gauges.
These data are being made available via user-friendly mapping services on Geoplatform.gov and Climate.data.gov.
New Release - U.S. Census Bureau International Population Data and Maps
The Census Bureau has added to and updated the online collection of subnational population data linked to maps (shapefiles) that are available at the Spatial Data Repository. The Repository contains a variety of data and maps primarily for countries that receive assistance via the President's Emergency Plan for AIDS Relief (PEPFAR).
To access the maps, start at the web page above and:
1. Click on Data in the ribbon below the title
2. Under the Select Countries tab at the left, click on Single Country
3. Choose a country in the dropdown menu immediately below the Single Country tab to see available data sets. Census Bureau population data and maps are available for the countries listed below.
- Africa: Botswana, Ethiopia, Ghana, Kenya, Lesotho, Malawi, Mozambique, Namibia, Nigeria, Rwanda, South Africa, Tanzania, Zambia, Zimbabwe
- Americas: Dominican Republic, Guyana, Haiti
- Asia/Europe: Cambodia, India, Indonesia, Russia, Thailand
In the near future, the Census Bureau will release a seamless global map containing population estimates for tens of thousands of subnational administrative areas globally.
The website below contains links to other Census Bureau international data and map products, including gridded data sets containing population estimates for 100-meter cells for several countries. These are ideal for obtaining neighborhood-level population estimates.
