Someone, somehow has mapped every little slough in about 300 square
miles of farmland about 20 or 30 miles north of me. There might be
2, 5 or 10 per square mile. Someone else has marked each railroad
level crossing. I can sort of see why this might be useful in a few
extreme cases.
But the programs which display the data, such as OSMAnd on the
Android phone and tablet, need an efficient way for me to mark those
POIs as I never want to see the darned things on my screen as they
are an intense amount of clutter.
