That is a real issue. The offline/online distinction is messsy, as you say, because of the various update times. I use offline mpas, but tend to update every few days (osmand live). But I see population as fundamentally different; the population doesn't change during an evacuation, and we don't have a tag for "how many people are currently within this boundary", which is the value that does change (and changes dailly due to commmuting, etc.). If someone were studying things like this and somehow had a graph of the number of humans within some administrative boundary by hour, they would certainly not label the y axis "population". _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
