i've recently been doing some mapping around auckland, adding coastal walkways. one in particular i walked on sunday has two routes: one at the foot of the cliffs, one on the road at the top of the cliffs. the lower route is under water when the tide is in, so walkers are advised to follow the road route.
so, i added the route, and it is now under water: http://www.openstreetmap.org/?lat=-36.927322&lon=174.709115&zoom=18&layers=M this seems wrong, drawing a route which is then under water, but the alternative of moving the path is also wrong. so, what do we do? the question becomes (in my mind): why do we have a single way mapped 'coastline'? this implies the boundary between land and water is static, but of course it moves - a number of times per day. i like the possibility of a high water mark and a low water mark, used together to entirely replace the natural=coastline tag. perhaps some of you have some ideas around this also? thanks, -- robin http://tangleball.org.nz/ - Auckland's Creative Space http://openstreetmap.org.nz/ - Open Street Map New Zealand http://bumblepuppy.org/blog/ _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
