Re: What returns from distance function?
I've seen a colleage use the following formula to get distance from the database,
( 6371 * acos( cos( radians(".$fLat.") ) * cos( radians( X(v.geo) ) ) * cos( radians( Y(v.geo) ) - radians(".$fLng.") ) + sin( radians(".$fLat.") ) * sin( radians( X(v.geo) ) ) ) ) AS distance
This results in a distance in KM, geo is a geometry field, fLat/fLng are well, lat and long ;)
Anyways, that might help you find you find out if the distance function related to meters or not.
