[HOT] GeoBucket Accuracy

hi Guttorm,

Thanks for the feedback that is a good idea, but unfortunately, we do not
store points as points. We store uploaded data in big bunches of points or
lines (as WKT). Adding accuracy on a per-point basis would mean a very big
overhaul of the app & site;

On the client we use phonegap (http://www.phonegap.com/) to access the GPS
values, and that gives us a value for accuracy in meters. We are not quite
sure if we could calculate the full HDOP from the data that the phonegap
API provides. We may have to extend Phonegap API to provide HDOP values,
since we have not come across anything similar within the native API.

So, one day, maybe.

regards,
David
