Are you kidding me? What part of "This is your Project of the Week. Make suggestions. http://wiki.openstreetmap.org/wiki/Project_of_the_week/Proposals " leads you to think that suggestions aren't welcome? ;-) Please write up a draft Project of the Week. Example tags are great. wiki-format is great. Pro-tip: The closer you make it to press-ready, the more likely it is to be selected. >> Are the rural ones visible from aerial imagery? > > Only if you have very very good imagery and know what you are looking > at.

Better to find an example on wikimedia commons, or to shoot your own example photo. The line between acceptable planning from a proprietary map, and unacceptable deriving data from a proprietary map is blurry enough to some. Why confuse it further? >> Perhaps we could start >> researching which states/areas have active sirens? Better to mobilize the crowd to map them. We'll get better quality from mappers than from an import. And mappers adding sirens are more likely to tag the rest of the park with the playground, sport field an water fountain. > Well, Iowa for sure and I'm sure most of the states that are in > "Tornado Alley" have them and are well tested.

Perhaps that should be a tag as well? man_made=tower siren=civil_defense siren:test= (something based on http://wiki.openstreetmap.org/wiki/Key:acces ) _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
