Hi, I need to find points (lat/lng) within a certain bounding box. To do so, I tried Geohash python implementation (http://mappinghacks.com/ code/geohash.py.txt).
Problem's data is : - I have 2 points (South west SW corner / North east NE corner) describing a geographic Bounding box - I have a model (let's call it 'Poi') having a field "geohash" of type Db.StringProperty + Lat and Lng field (Float) Question is : How on earth (lol :-) ) can I find all Poi within my bounding box ? I've already tried something like : Create Geohash for SW, create Geohash for NE and do something like : "SELECT * FROM Poi WHERE geohash >:1 and geohash <= :2, geohash(SW), geohash(NE)" Also tried with geoindex, at different depth but all this fails and still give points not located within Bounding box. Also tried like describe in "http://labs.metacarta.com/blog/27.entry/ geographic-queries-on-google-app-engine/" to create a small surrounding box for each Poi and then create a geohash for this specific bounding box to be in between my SW->NE bounding box.... Nothing is working even with "not worst case" (I mean equatorial problem...) case/ Any help will be greatly appreciated.
