After gathering information from some very good guide maps out there (especially by Bharat), and some hours spent on Google Earth + Photoshop, i finally managed to create a map for my reference, for my first upcoming trip to Ladakh. Although my wife has been there before, i am yet to be there.
Hope this helps some of you. The distances marked are a little tentative, i hope to mark my trail on GPS while on the trip and mark correct distances and complete the map when i'm back.
In the meanwhile, people who've already done the Leh trips, and have experience could guide me at places where i've gone wrong in the map. This would help me greatly on my trip as well.
Edit: here is the updated map after the trip.
