Atal Nagar — terrain-driven water flow across all 40 sectors
Same hydrology pipeline as the Raipur map, re-clipped to the Nayaraipur bounding box. We start from the 30 m Copernicus DSM, hydrologically condition it with WhiteboxTools' least-cost breach, then derive D8 flow direction and log-transformed flow accumulation across the Atal Nagar grid. The result is smoothed and reclassified into 5 graduated bands so darker teal indicates a higher likelihood of runoff concentration.
Sector centroids in the dropdown are deterministic grid approximations of Nayaraipur's 8 × 5 sector layout. They give you instant focus on the right neighbourhood while the underlying flow surface comes from the DEM, not the sector boundaries.
