I have a large collection of pictures with GPS locations, encoded as lat/lon coordinates, mostly in Los Angeles. I would like to convert these to (1) zipcodes, and (2) neighborhood names. Are there any free web services or databases to do so? The best I can come up with so far is scrape the neighborhood polygons from the LA times page and try to find out in which polygon every coordinate is. However this might be quite a lot of work, and not all of my coordinates are in LA. As for the zipcodes, this 2004 database is the best I can find, however zipcodes are encoded as a single coordinates

Is there any such API where given a location (in terms of latlong), I could find whether the given point is on road/street or not. And if possible also gives me nearest street/road to that location. I found API from [Find nearby Streets] -> http://www.geonames.org/maps/us-reverse-geocoder.html#findNearbyStreets , but it just gives solution for US. Help me if u know of any better solution/algorithm. ( I am particularly interested in India.) Mathias Schwarz You can use the Google Maps Geocoding API which does exactly that: https://developers.google.com/maps/documentation/geocoding/intro Take a

I'm trying to build an application that will use open source maps from Open Street Maps (though the concept should be applicable to any map provider). The application will enable the user to specify a number of waypoints along a route prior to departure. Because I don't have a data plan for my cell phone (and because rambling in the countryside rarely gives you a good connection), I want to be able to pre-load the relevant map tiles for the waypoints and/or route before departure so that maps can continue to be used without a data connection. My initial thoughts are to download the required

I have used OpenStreetMap in my ongoing website. I have developed website using PHP. My requirement is to get ADDRESS based on Geo Location(Latitude & Longitude). Is there any OpenStreetMap API available to get location info based on Lat/Lon? Thanks, Vishal Parmar There are multiple reverse geocoding APIs available for OpenStreetMap (since the data is open-source, anyone can build one). The two that I would recommend you investigate further are: Nominatim, run by a member of the OSM community as a volunteer project. Reverse Geocoding documentation CloudMade Geocoding, run as a commercial

Suppose I have a route defined from one town to another. From the Google Maps API I can recover a route between the two. However, the route returned from Google is a driving route that includes geo-coordinates only at places where there is another step in a leg (for example, where I have to turn from one highway to another). What I need is geo-locations (lat/long) along the entire route, at specific intervals (for example, every 1/4 mile or 100m). Is there a way to accomplish this via the Google Maps API / web services? Or would the OpenStreetMap database be the way to do it? Kind regards,
