Over one century’s worth of data have been collected for the western United States, exclusive of Alaska. These data have been compiled from historic photos and maps, digitized in heads up mode and quality checked by multiple participants. These data represent from 2 to 11 timeslices per glacier for 59 glaciers in 5 regions from Montana to California. In some cases we document glaciers that no longer exist. More data are being processed and we are also including temporal data from satellite imagery.

We are currently in the process of converting these data to be consumed as web services (OGC compliant) by other websites or by rich desktop clients. The Web Map Service (WMS) can be queried by spatial or temporal extent. The spatial extent is handled via the familiar bounding box parameters passed in during a WMS request. The temporal query is handled via the Filter Encoding specification in the Styled Layer Descriptor (SLD) specification. A possible future version will support the KML standard.
