The value given by each survey station depends on its position (proximity to the road, regulatory height in reference to that of professional control stations).
Could it be significantly relevant from a scientific point of view to be able to look at the map by filtering only the stations at a more regular height (3/4 meters) than the others? It’s correct?
It might be interesting this way, to push everyone to place stations more evenly if possible to provide better statistics. Mine is just an idea, what do you think?
I am doing a lot of off-line tests varying only the height (2 - 15 mt range): the result changes a lot even if I live in a small country village, who knows how much it changes in bigger cities.
