The National Snow and Ice Data Center's (NSIDC) Atlas of the Cryosphere Web site allows visitors to explore and dynamically map the Earth's frozen regions. Viewed from a polar perspective, the available data sources include snow cover, sea ice extent and concentration, glaciers, ice sheets, permafrost, and other critical components of the Earth's cryosphere. Users can zoom in to a specific region on the Earth as well as overlay country borders, major cities, and other geographic information. This site should act as a useful tool in science and education efforts surrounding the International Polar Year (IPY) (2007-2008) and beyond by providing a geographic tool for viewing snow and ice on the planet.
In addition to providing an interactive Web interface, maps and source data contained in the Atlas of the Cryosphere are also accessible via the Open Geospatial Consortium (OGC) Services Web site. From this Web site, interoperable and customizable data access to the Atlas of the Cryosphere maps and source data are enabled via the following OGC specifications: Web Map Service (WMS), Web Feature Service (WFS), and Web Coverage Service (WCS). These international specifications provide a framework for sharing maps and geospatial data over the internet.
We welcome your feedback on this project. If you have questions, comments, or suggestions, please contact NSIDC User Services at +1.303.492.6199, email@example.com, or via our online contact form. The development of this map server application was supported by NASA's Earth Observing System (EOS) Program and was developed using MapServer, an Open Source development environment for building spatially-enabled Internet applications.
