Results show marked changes in that system over the last 30 years, but also point out the need for establishing clear protocols for glacier monitoring from remote-sensing data. We present an example analysis of change in Cordillera Blanca glaciers, as determined by comparing data in the GLIMS Glacier Database to historical data. has been designed at the National Snow and Ice Data Center (NSIDC, Boulder.
The glacier and ASTER footprint layers may be queried for scalar attribute data, such as analyst name and date of contribution for glacier data, and acquisition time and browse imagery for the ASTER footprint layer.Global Land Ice Measurements from Space (GLIMS) is an international.It specifies the formats and conventions for the files that convey these data. Map layers include glacier outlines, footprints of ASTER satellite optical images acquired over glaciers, and Regional Center information. GLIMS analysis performed at the Regional Centers (RCs) to NSIDC (National Snow and Ice Data Center) for ingest into the GLIMS (Global Land Ice Measurements from Space) data base.

There, users can browse custom maps, display various data layers, query information within the GLIMS database, and download query results in different GIS-compatible formats. The GLIMS Glacier Database is accessible on the World Wide Web at “ ”. The WMS, an Open Geospatial Consortium (OGC)-compliant web interface, makes GLIMS glacier data available to other data servers. Data received by the GLIMS team at the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado are ingested into a spatially-enabled database (PostGIS) and made available via a website featuring an interactive map, and a Web-Mapping Service (WMS). We are increasingly flexible on the formats of data that we can accept. This will notify people in both the GLIMS and RGI (Randolph Glacier Inventory) communities. Each institution (called a Regional Center, or RC) oversees the analysis of satellite imagery for a particular region containing glacier ice. If you have data to contribute to GLIMS (glacier outlines, center lines, snow lines, and the like), please let us know at . NSIDC distributes four of the six data sets selected to represent key climate variables in Earth’s frozen regions, known collectively as the cryosphere: the Sea Ice Index (Fetterer, F., et al.), the Global Land Ice Measurements from Space, the Antarctic 1-kilometer Digital Elevation Model (Bamber, J., J. The Global Land Ice Measurement from Space (GLIMS) project is a cooperative effort of over sixty institutions world-wide with the goal of inventorying a majority of the world's estimated 160 000 glaciers.
