geocoding

I am making an app which will take user's current location or his customized map marker to find out lat & long and then using those values I would like to know pincode(zipcode) of that area so that I can tell user whether goods can be delivered in that area or not. I have tried this : http://www.geonames.org/export/ws-overview.html but it doesn't have full data and whatever it has is not very accurate. Is there any other API which I can use to get such data? geocodezip If you have a location (and a Google Maps API v3 map), reverse geocode the location. Process through the returned records for

I got the current location based on the Longitude and Latitude values and then I also got multiple places on google map using Annotation. Now I want to get the longitude and latitude values based on the Address( i.e street,city and county).Need some guidance on how this can be achieved. Till now, this is what I have tried:- #import "ViewController.h" @interface ViewController () @end @implementation ViewController @synthesize streetField = _streetField, cityField = _cityField, countryField = _countryField, fetchCoordinatesButton = _fetchCoordinatesButton, nameLabel = _nameLabel,

Given a latitude and longitude, and distance, I want to find a bounding box where the distances are less than the given distance. This questions was asked here: How to calculate the bounding box for a given lat/lng location? I donot want this partcularly accurate, so I have modified and simplified it to def boundingBox(latitudeInDegrees, longitudeInDegrees, halfSideInKm): lat = math.radians(latitudeInDegrees) lon = math.radians(longitudeInDegrees) halfSide = 1000*halfSideInKm RADIUS_OF_EARTH = 6371 # Radius of the parallel at given latitude pradius = radius*math.cos(lat) latMin = lat -

I got the current location based on Longitude and latitude values and then I also got Multiple places on google map using Annotation now I want get longitude and latitude values based on Zip code I don't know how to get Longitude and latitude values base on Zip code this is the method for call google map api for geocoding, if u pass the Zipcode/Postal code, you get the result -(void)ViewDidLoad { NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@"

Whatever service that would allow something as simple as 100 geo transcoding requests (from street address to geocode) would be ideal. I know that google maps allows 15000 daily, but it is written in Javascript. I was wondering if I could get something written in a language that at least allows for database connections. There's a non-JavaScript variant of the Google Maps geocoder (check the TOS - you'll need to be doing this to eventually display stuff on a Google map), and you're not going to find any geocoding services that allow a direct database connection. You could also use OpenStreetMap

Google offers a wonderful REST interface for geocoding and reverse geocoding an address. My API key is valid, and if I enter the request directly into the browser address it works great. However, the following jquery fails terrible and I'm failing to see why. Hoping you could help me out here. $.getJSON("http://maps.google.com/maps/geo?q="+ address+"&key="+apiKey+"&sensor=false&output=json", function(data, textStatus){ console.log(data); }); Google's REST interface doc for this service: http://code.google.com/apis/maps/documentation/geocoding/index.html The problem here is that I wasn't
