Neto, are you using the REST API or this with business logic?

Hi Michael! I'm using both collection hook and iOS Framework

When using the iOS library (or the REST API) specify maxDistance in miles. When using business logic, such as with a collection hook, the maxDistance is specified in radians. (http://stackoverflow.com/questions/3878702/mongodb-bound-queries-how-do-i-convert-mile-to-radian might be helpful)
Neto Leal
metersToMiles = 0.000621371;
maxDistance = radiusInKilometers * 1000 * metersToMiles / 3963.192;
For example, for a radius of 15km the query body is the following:
{"_geoloc":{"$nearSphere":[-46.683750199999999,-23.594244364991852],"$maxDistance":0.0023517822846770287}}
any help?
thanks
