The map is at a scale of 1:500,000 and covers the whole of NE India plus Bangladesh and Bhutan. It's printed on 2 sides - so this is helpful if you are travelling but there is a considerable amount of overlap between the 2 sides. There are also city maps of Dhaka and Central Kolkata but neither of these are likely to be of much use if visiting those cities (which anyway don't lie in NE India which is normally considered as the 7 states of Sikkim, Assam, Arunachal, Nagaland, Manipur, Mizoram and Tripura and Meghalaya). Better would have been small inset-sized city maps of the 7 capitals of these states.
To get an overview, this map is OK. It's clearly presented and main features can be seen. If you are really only interested in India's NE states - the excess areas covered are a bit superfluous. Had I wanted a map of Bangladesh (or Bhutan) I would have purchased one separately since they are available at larger scale. Since the 2 sides of the sheet are being used it would have been possible to cover these states at a larger scale with less overlap and avoiding these other countries. This would have given better value for money and given a more detailed map - as well as leaving space for the city inset maps. However, this is one of the few maps available (readily) covering this area so in that sense it has proved useful as a guide to this fascinating and less-visited part of India.
