Outline of data set for Glacier Inventory

Long-term glacier area change in Eurasia Cryosphere region is clarified by integration of topographical maps and aerial photographs and satellite image. The method of extracting glacier information is developed by automatic recognition technology of a images.

Glacier Inventory in Mongolian Altai Mountains

• The glacier area of distribution from the topographical map created based on the aerial photograph for 1945 - 47.
• The glacier area of distribution extracted based on the satellite imagery in 2000.
