From which Munro can you see the most other Munros?
(Munro = Scottish mountain over 3000ft. There are 282 Munro) This question was posed during a few day's walking in Knoydart in September 2021. There wasn't any sort of answer online, so I set about finding it. There are two factors to whether you can see a hill from another hill: If there is another hill in the way (taking into account the curvature of the earth) If the atmosphere is clear enough - even if there are no clouds in the sky, after some distance there becomes too much haze It is clear from (2) that the answer will vary day to day! So I suppose the question then becomes two questions: From which Munro can you see the most other Munros if distance is no object From which Munro can you see the most other Munros given the viewing distance is x kilometres Clearly if a way of answering the first can be found, the second will easily follow by filtering. To attack the first part I used QGIS, a free geographical information system application, to analyse a DEM (digital elev...
