Just use Lat/Lon. You can fidget over which ojection to use later as long as your data is good. (WGS84 is the best btw)
I agree lat long sounds beautiful to me! Well thats good. For geolocation, you can use the HTML5 Geolocation API that will use the person's browser to give you a location usually accurate to 200m (better if they're on a phone with gps), more than enough given your search radius of 200miles. Oh okay ill keep that in mind in case i make a iphone app cause right now i like the idea of lat long. For distance lookups, go with a simple bounding box algorithm (bounded by map edges, distance calc by pythagoras). Again exact positioning is NOT ESSENTIAL for your use case, especially on the 25mi scale. What about a circle? Use lat long equated to a city or address and do a circle with that point in lat long and find all the data within the circle? If you ever find yourself needing better/more accurate position calculation. use postgis, but never install from source, use your distro's packages (it Just Works tm). Should be called 'postgresql-9.1-postgis' on most distros. do a search. make sure you have libproj and libgeos installed as well. Is "it just works" a programming catch phrase? Haha. Yes the distros this next time not the other way. -- You received this message because you are subscribed to the Google Groups "Django users" group.
