Can cell 4770003039 see its neighbour?
A curvature-corrected line-of-sight from this Hingoli cell to its nearest neighbour, traced over the 30 m DEM and building-height surface. The physics is field-determined; outside the raster footprint, or across DEM nodata, the engine refuses rather than ever assuming "visible".
Line-of-sight refused — outside raster support
no 30 m raster support for admin 477 This is the honest answer: visibility is gated to the 30 m DEM + building-height footprint, and a sight-line that leaves that footprint (or crosses DEM nodata) is refused rather than ever silently reported as "visible". A refusal is content here, not an error.
Many MH-36 cells fall outside the building-height raster footprint, where line-of-sight is not yet determinable. Missing is never "visible".
