There have been some great ideas and thoughts that poured through the list yesterday. Here's an attempt to summarize and re-gather thoughts and needs. I think there are couple of use cases people have thrown out there, each with their own problems and possible solutions (completely up for discussion). I just want to have us arguing about the appropriate topics and not bashing head on what the actual problem is. :)
--- 1) Precision Summary: ability to mark the approximate area these lat/lon coordinates apply to due to not sure of exactly where something was, or imprecise measuring device Example: have lat/lon of the center of a park, and took pictures at various places in the park. Problems: users probably don't know that 0.0001 degree = 11.1 meters at the Equator - but also varies depending on the latitude. Also, dropping digits off the end doesn't specify if 41.345 is "inaccurate", or really accurate 41.3450000 (b/c zeros would be dropped when stored in code as a number, though not as a string) Solution? specify a precision that is +/- a distance. e.g. "give or take <span class="precision">10 meters</span> 2) Radius Summary: rough area that the coordinates apply to Example: expected landing area for a parachutist/rover Solution? allow <span class="radius">42 meters</span> 3) Feature area Summary: coordinates are the center of a larger area of a certain type of unknown size Example: Took a picture of a mountain or a city. Want to just say, the mountain is at Lat x Lon and is a mountain in size/area Solution?: featuretypetag="mountain" as used by GeoRSS 4) Polygon/line Summary: lay out a track/line, or define a specific boundary of a location Example: A hike or a plot of land definition, such as for Real Estate Solution? Use an ordered list for a line <ol class="track"><li class="geo"> .... and the same for a polygon: <ol class="polygon"><li class="geo"> ... Also look at the directions uf discussions. --- Andrew Turner _______________________________________________ microformats-discuss mailing list [email protected] http://microformats.org/mailman/listinfo/microformats-discuss
