----------------------------Original message---------------------------- I would appreciate pointers or information on who may be doing GIS involving mountain ice fields and glaciers. Also, have there been long term studies using satellite information (outside of the NASA work on the Arctic Ocean, for example)? In planning a basin model I note ice fields and glaciers within the area involved. I've not touched a glacier beyond a stroll on the Grossglockner and know nothing of the state of that art.
