gps

I want to get my coordinates every minute, even if a user is not moving. So i used requestLocationUpdates with the following parameters: locMgr.requestLocationUpdates( LocationManager.GPS_PROVIDER, 60000, // minTime in ms 0, // minDistance in meters PosljiLokacijo.this); But when i test it on my HTC Hero (2.1 Android) and i am not moving, onLocationChanged() is never called. If i change minDistance to 1, then i get a few updates at start but after that, they come in very unregular intervals. How should i choose these 2 parameters (minTime and minDistance) to receive coordinates every minute? I

I am trying to get the GPS location of my G1 using the following code In Activity MyLocationListener myListener = new MyLocationListener(); LocationManager myManager = (LocationManager)getSystemService(LOCATION_SERVICE); myManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 0, myListener); This is the LocationListener class public class MyLocationListener implements LocationListener { private static double latitude; private static double longitude; @Override public void onLocationChanged(Location arg0) { latitude = arg0.getLatitude(); longitude = arg0.getLongitude(); } @Override

I´m playing a bit with the iPhone SDK and I want to show the current speed in my application. There are so many apps that can do that really precise, especially for low speeds like running or biking. The best I've seen is RunKeeper. But, in my application, the speed is absolutely inaccurate. In low speeds it is always null, and only at higher speeds it shows some values but they are rarely updated and not really useful. - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { if (newLocation.timestamp >

I am receiving data from a gps unit via a udp packet. Lat/Lng values are in hex. Example Data 13BF71A8 = Latitude (33.1313576) BA18A506 = Longitude (-117.2790010) The documentation explains that longitude/latitude readings are measured in degrees with a 1x10^-7 degree lsb, signed 2’s complement. For the Latitude I can convert using this formula: 13BF71A8 = 331313576 * 0.0000001 = 33.1313576 This code works for Lat but not for Lng: function convertLat(h){ var latdec = parseInt(h,16); var lat = latdec * 0.0000001; return lat; } console.log("LAT: " + convertLat("13BF71A8")); I am having trouble

Draw a circle in KML How do you take the GPS coordinates of a point on the globe (say in decimal degree format) and generate the coordinates for a polygon approximating a circle centred on that point? A polygon with 20+ data points looks like a circle. The more data points - the better looking the circle. I am writing a program that will generate KML and dont know how to calculate the coordinates of the polygon vertices. Example of data inputs: Latitude, Longitude, Circle radius (in feet), NumberOfDataPoints 26.128477, -80.105149, 500, 20 arx I don't know if this is the simplest solution and

public void onCreate() { locationListener = new GeoUpdateHandler(); locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); try { gps_enabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); network_enabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); } catch (Exception ex) { } if(gps_enabled) { locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, TIME_DURATION, 100, locationListener); } else if(network_enabled) { // Checking for GSM locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, TIME
