geolocation

This question already has an answer here: Best way to determine user's locale within browser 7 answers Question: Is there a javascript (client-side) code to get visitors country/language code, that is accurate and is cross-"modern"-browser ? I am looking for results like 'en-US' , 'sv-SE' , 'nl-NL' , etc. Related questions to this have been asked before (some SO links: 1 , 2 , 3 , 4 , among others) but I didn't find answer and some of the answers are some yearls old and in some cases referring to even more old articles, which makes me think there are new solutions for this. I tried : var

I need a list of countries, states & cities based on a collection of lat/long values I have. I need to store this information in a manner that hierarchy is preserve and without duplicates (e.g. "USA" and "United States" and "United States of America" are the same country; I only want one instance of this country in my database). Is this possible to do with Google Map API? What you are looking for is called reverse geocoding . Google provides a server-side reverse geocoding service through the Google Geocoding API , which you should be able to use for your project. This is how a response to the

If I have a latitude or longitude reading in standard NMEA format is there an easy way / formula to convert that reading to meters, which I can then implement in Java (J9)? Edit: Ok seems what I want to do is not possible easily , however what I really want to do is: Say I have a lat and long of a way point and a lat and long of a user is there an easy way to compare them to decide when to tell the user they are within a reasonably close distance of the way point? I realise reasonable is subject but is this easily do-able or still overly maths-y? b-h- Here is a javascript function: function

For example if we have these set of coordinates "latitude": 48.858844300000001, "longitude": 2.2943506, How can we find out the city/country? Kevin The free Google Geocoding API provides this service via a HTTP REST API. Note, the API is usage and rate limited , but you can pay for unlimited access. Try this link to see an example of the output (this is in json, output is also available in XML) https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true Michael Borgwardt Another option: Download the cities database from http://download.geonames.org/export/dump/

I must be missing somthing out in the docs, I thought this should be easy... If I have one coordinate and want to get a new coordinate x meters away, in some direction. How do I do this? I am looking for something like -(CLLocationCoordinate2D) translateCoordinate:(CLLocationCoordinate2D)coordinate translateMeters:(int)meters translateDegrees:(double)degrees; Thanks! Unfortunately, there's no such function provided in the API, so you'll have to write your own. This site gives several calculations involving latitude/longitude and sample JavaScript code. Specifically, the section titled

Is it possible to get the current location of user without using GPS or the internet? I mean with the help of mobile network provider. What you are looking to do is get the position using the LocationManager.NETWORK_PROVIDER instead of LocationManager.GPS_PROVIDER . The NETWORK_PROVIDER will resolve on the GSM or wifi, which ever available. Obviously with wifi off, GSM will be used. Keep in mind that using the cell network is accurate to basically 500m. http://developer.android.com/guide/topics/location/obtaining-user-location.html has some really great information and sample code.
