Can cell 4820000033 see its neighbour?
A curvature-corrected line-of-sight from this Mumbai 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".

The sight-line from cell 4820000033 to neighbour cell 4820000034 is obstructed over the 30 m elevation + above-ground building-height surface, with Earth-curvature and atmospheric refraction applied. This is a field-determined geometric fact, not a model estimate.
