Height data often contains NODATA over a water body. If you do visibility analysis in an coastal area, eg check if an aircraft or a mountain (point with lat1/lon1/alt) is visible from a ship (point with lat2/lon2/alt=0) or vice versa, the analysis without the NODATA fix is not possible. The NODATA values is normally defined in the raster data and is often -10000.
NODATA values are now omitted in plot as of c2a9a700307c2bd6072b7e74a519157b2d7ddee4
Replace SRTM NoDataValue (-10000) with 0.
