php - How would you rate Open Street Maps reliability? -


i'm constructing geo location mobile app , i'm @ crossroads of api integrate with. guess 2 biggies google maps , open street maps. hear google start charging api in fall , i'm not sure app profitable then, i've decided go open street maps.

the thing i'm wondering if open street maps reliable enough prime time. i've tried queries, , honest couldn't find couple of locations here in georgia. i've never had problem google maps. has has been using open street maps had problem it's reliability? i'm building ios app , know, ios doesn't have geocoder can tell latitude , longitude address, that's why have @ other alternatives. backend php making calls mapquest's nominatim implementation (no query limits) via curl if it's consolation.

there conceptual difference between google maps , open street maps. former commercial product (even if @ moment free) provides access features clean, mature apis (geocoding, map tiles, client-side apis). can not everything might need, example can not change map colors, or have restaurants drawn, etc.

open street maps not product, better huge, open geographic database. can query information in forms of polygons, points, areas. have draw map yourself. can on client side (if have enough cpu) or @ server side , download map tiles images. mapquest you: renders map open street maps db , gives access tiles. subsidiary services geolocation available around open street maps not strictly connected , can use other more specific services (for example there database contains mountain peaks of earth).

as of experience, open street maps db contains quantitatively more , more refined information google maps , might how many , kind of information draw on map tiles (if don't use rendering services). anyway, have more flexibility price of more work.
