What the library is
Naapi's shared map library holds the portal's revenue maps, already downloaded and labelled by district, anchal, mauza, survey and sheet, so a sheet opens with one tap instead of a search on the portal and a file to manage. Sheets are stored as the portal published them; nothing is redrawn.
The library is open to signed-in users, or to everyone when the owner has switched on Map library without signing in. In the app, open the 📚 Map library fold under 1 Map, choose district › anchal › mauza, and tap the sheet; or type a mauza name or thana number in the search box. On a satellite view, the 📍 chip names the mauza under the middle of the map and offers its sheets.
Districts in the library
Every district has its own page listing each of its mauzas, by anchal, with the thana number and the sheets held for each survey — CS (Cadastral Survey), RS (Revisional Survey) and Chakbandi. Names are as the portal spells them.

A mauza that is not here
Every other village of Bihar is still in the index the app carries — its name, thana number and, for most, its position on the ground — so it is named on a satellite view and can be searched; only its sheets are missing. Download them yourself from the Bhu-Abhilekh portal as described on the portals page and open the file directly: the app measures it the same way. The owner loads whole anchals into the library from the portal's map listing; ask for yours.
