A collection of historical maps produced by the Survey of India from 1750 to the present day, with scales ranging from 1:1,000,000 to 1:50,000. When published these maps were the definitive geographical record of their day, and now they are difficult to find except in a few specialized library collections..
All properly scanned (300+ dpi .jpg images) maps published by the Survey of India, covering the territory from Iran to China, are eagerly sought for this collection.
