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.
