Geography: features are those on our Geography map that cover a good part of the state (or that NCERT places in it); hazards, reserves, crops, minerals, industries and ports are where NCERT, UNESCO or the Ramsar list name or place them. Census figures are for 2011, as NCERT prints them.
How this is made: nothing here is new — it is YugMap’s own map data sorted by today’s states. A kingdom is listed if its territory on our map covered at least 40% of the state at some point, or if its centre or capital lies here; events and places are listed where their map point falls inside the state. State outlines follow India’s official map.
