GLACIERS

For a better understanding of these transformations, the cartographic model can be displayed in a new window.

After manipulation of the imported ArcView theme "icefields_and_marshes.shp", and rasterizing the vector image, the result is a raster image of glacial cover:

Reclassifying the image, in order to make it "transparent" for OVERLAY:

Overlay of glacier on top of DEM:

Calculating the average minimum altitude of glaciers using HISTO:

CONCLUSION:

Approximate minimum elevation of glacial extent at study site 82: 2400m

Approximate minimum elevation of glacial extent at study site 92: 1975m
