I have a forest field, with paths and points of interest, and I would like to make a map of it. I cannot do it with a drone, because it's expensive and I will not see paths on pictures because of the trees.
So I thought about mapping it with my smartphone and its GPS sensor.
For example, I would walk on all the paths on my field, input to my smartphone that I am on the "Alpha point of interest"... And then I'd like to export data and get the map and its points on a map service like Google Maps.
I found some tracker apps, but it seems to be more for running or sport usages, and not for pure mapping.
I have both, Android and iOS devices – so an app for either of them would be fine.
