Interesting. after hearing all the frustration on sloppy mapping after Hurricane Matthew and slogging through too many unsquared buildings and duplicates, etc myself, I stumbled across a map in #2235 (Hurricane Matthew: Gris Gris) at http://tasks.hotosm.org/project/2235 that had an amazing number of clean tiles that I validated. I don't think it could be that much of a coincidence that an entire map had such clean mapping. Instead of spending my time adding buildings and squaring them and removing duplicates or overlaps, I was able to go from one tile to the next, quickly checking for anything overlooked and validating it.
I'm wondering if there was something different with that map than others. Did a particular group lock it down or something? Is there something that can be learned from a map that somehow got it right? I would love to find out how to apply whatever happened to that map, to other maps and mappers. It was a real joy to validate those instead of dreading how many hundreds of careless errors I would find from one tile to another. BTW, that map (#2235) is completed and validated and can be archived. Regards, Jim Smith
