Please suggest methods based on Raster data set processing.
Is there any model that I can use to delineate accurate extent of a Glacier?
Please suggest me. Thanks
Peeyush @ thanks for your reply. But Peeyush I am interested to use raster based options.
please send me any manual or research article on that so i can understand it better. thanks
Hello Vishal,
Just in case it may help you explore this from a different angle, have you tried contacting researchers from the glacier research groups elsewhere ?
One such group is at the University of Bristol'School of Geography (UK) where they have been working extensively with radar datasets for many years,especially with large ice caps (Groendland, Antartica).
If you are interested in small mountain glaciers, on the other hand, Harry Zekollari from the Department of Geography at VUB, in Brussels (Belgium), is advancing well on a PhD modelling the 3D evolution of such small glaciers and should be able to suggest specific colleagues who are assembling datasets using radar remote sensing, as he also uses such data to assess and calibrate his own modelling efforts, on a regular basis.
Changing perspective a little, such measurements can introduce considerable DEM distortions and a colleague of mine, Professor Matthieu Kervyn, also in the Department of Geography at VUB has examined the biases involved in trying to do what you are trying to do for glaciers but for small volcanic cones and I suspect also now for bigger volcanoes.
Matthieu has published at least a couple of papers on DEM dérivations from remote sensing data (including SRTM) which also list the few other studies carried out in order to assess DEM quality in the volcano context.
Another expert of DEM derivation for volcanoes is Thomas Walter (GFZ, Germany) and he may also want to add his advice should you contact him.
This is what comes to mind just now.
I hope it may contribute to pointing you in a helpful direction for your research.
With best wishes and kind regards,
Gerald

Vishal,
You are most welcome.
You may have noticed that both Matthieu Kervyn and Harry Zekollari are on Research Gate - readily contacted through RG for starters.
All the very best,
Gerald
Our lab just finished the 2nd inventory of Chinese glaciers and many methods have been adopted, including the romote sensing images, in situ measurement, et al. If you are interested in that, please contact with professor Shiying Liu and Tao Che in Chinese Academy of Sciences.
