ATDI map

Has anyone tried extracting just a certain region's map from the maps provided by ATDI? I needed Nepal's DTM, which is available in Tibet-China dataset in ATDI's map.
I have tried Global mapper with ATDI plugin without any success. Any help would be highly appreciated.

Here's the link of ATDI map

Thanks

These maps are projected China(Lambert)CHLAM. May be somebody knows the parameters of this projection ?

A search for China Lambert at https://spatialreference.org gives 3 results with this being the most likely one https://spatialreference.org/ref/sr-org/6959/ that page has a .PRJ file you can download and use in Global Mapper. Hope that helps.

BR's, Stan.

I have tried projections from that site, but it didn't result in accurate output. I'll give it a shot once more as I could be doing something wrong.

Thanks a lot
