The GLIMS Glacier Viewer is an interactive map which gives a view of data in the GLIMS Glacier Database. A number of different layers in this interface can be viewed and spatially queried including: GLIMS Glacier Outlines, ASTER Footprints, Regional Center Locations, the World Glacier Inventory, the Fluctuations of Glaciers, and others. The GLIMS Glacier Outlines layer contains the results of glacier mapping within the GLIMS initiative. Each polygon in this layer represents the extent of a particular glacier at a specific time, as well as other possible features of the glacier such as the extent of debris cover or the location of supra-glacial and pro-glacial lakes. The GLIMS Glacier outlines can also can be downloaded as ESRI Shapefiles, MapInfo tables, Geographic Mark-up Language (GML) files, Keyhole Mark-up Language (KML, Google Earth), and the Generic Mapping Tools (GMT) multi-segment format.

This interface provides access to the GLIMS Glacier
Database through a text-based search form. The paramaters one can search on,
as well as the result fields that can returned, are customizable. This
allows the user to search on and return only the criteria that are relevant
to their needs.
Query results in this interface can be downloaded individually or as part of the larger result set. Downloaded data are available in the same formats as from the mapserver interface (above).
Another way of accessing data within the GLIMS Glacier Database is through the
Open Geospatial Consortium's (OGC) Web
Map Service (WMS) and Web Feature Service (WFS) protocols. These services allow
access to GLIMS Glacier data directly from desktop GIS software products such
as ArcGIS, GRASS, or Google Earth, as well as other applications such as
MapServer. The following URLs can be used to connect your OGC-compliant
application to the GLIMS Glacier Database.
To access the capabilties (list of available layers) of the GLIMS Glacier Database, use these URLs:
