Ten statutory checks on a plot, before anyone drives out to it
Upload a site boundary and every clearance the plot needs is screened against live map data in about a minute.
The problem
Before a plot in a city like Mumbai can be built on, it has to be cleared against a long list of authorities: railways, metro, forest, highways, defence land, drains, the coastal zone. Working out which of those actually apply is done by hand, by someone who knows where to look, and it takes days. Get it wrong and you find out months later, when the file comes back.
What we found
Every one of those checks is the same shape underneath. Take the site boundary, measure the distance to a thing on a map, decide whether the rule bites. The judgement in that is real and worth paying for. The looking up is not, and it is the part that eats the week.
What we built
Purview takes a KML of the site boundary and screens it against ten checks at once: CRZ, railway, metro, forest, highway, defence, TOD applicability, tree cutting, nalla and HT line. Each one comes back with the actual number attached, so a metro line fifteen metres away reads differently from one two hundred metres away, instead of both being a yes.
You can see why it flagged
The whole thing sits on satellite imagery with every layer switchable: railways, metro lines and stations, wooded land, highways, defence parcels, drains, and the screening buffer itself. A flag you cannot check is a flag nobody trusts, so the map always shows the thing that caused it.
The result
What comes out is a screening report, with the flagged items, the clear ones and the ones still outstanding kept apart rather than mixed into one list. A first pass that took days now takes minutes, and the days go to the two or three checks that genuinely need a person.
