isn't the issue here that radioactivity is like height, i.e. a smoothly-varying value that exists everywhere and is typically represented as gridded data (which gets converted to contours for display).
with height, people said that the grid data was unsuitable for going into OSM because OSM is point/line/area, and that it would be confusing if you had huge grids of nodes for each sample of height/noise/radioactivity/ground colour. (the location of radioactive sources OTOH would be fine (similar to television towers in the radio spectrum), as would 'areas marked with warning signs' (similar to danger areas, as mentioned already)) _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
