gps

I have a GPS coordinates of several points and I want to know if they are on a highway, or trunk road, or minor road, and it would be even greater if I could identify a road name. I'm using R leaflet to draw maps and I can see with OpenStreetMap that different types of roads are colored differently, and I wonder how I can extract this information. It's not a problem to use Google maps instead if it will solve my problem. I would appreciate any help. You can use revgeocode() from ggmap : library(ggmap) gc <- c(-73.596706, 45.485501) revgeocode(gc) Which gives: #[1] "4333 Rue Sherbrooke O,

How would I go about obtaining the GPS cordinates in a windows mobile application? The sample app that comes with the SDK doesnt seem to work. I also have the wm 6.5 SDK which I heard had GPS stuff but I cant find it. Let me know if you have any good examples. Go with GPS.Net . It's an excellent library, very easy to use and compatible with a whole pile of hardware implementations. We used it for Windows Mobile and Windows Xp/Vista versions of an application. As of WCE 5.0 microsoft includes a gps intermediate driver which sits in front of the devices gps device and provides an api for

I'm developing an android app in which I need to show location updates with some 30-40 updates per second. I'm using the Location APIs of Google Play Services , introduced in Google I/O 2013. It uses a fused location provider (making use of accelerometers and other sensors along with GPS) for more accurate & efficient location tracking. Here's my code: protected void startLocationTracking() { if (GooglePlayServicesUtil.isGooglePlayServicesAvailable(this)) { mLocationClient = new LocationClient(this, mConnectionCallbacks, mConnectionFailedListener); mLocationClient.connect(); } } private

This question already has answers here : How do I get the current GPS location programmatically in Android? (22 answers) Closed 2 years ago . I have tried searching for answers online but they seemed to work only for android versions 4.0 and below public static boolean isLocationEnabled(Context context) { int locationMode = 0; String locationProviders; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){ try { locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE); } catch (SettingNotFoundException e) { e.printStackTrace(); return false; }

I write this code to receive location updates - PendingIntent launchIntent = PendingIntent.getBroadcast(context, 5000, intent, 0); manager.requestLocationUpdates(selectProvider(), 0, 0, launchIntent); I select the gps provider if its available, otherwise the network provider. Is there a way I could switch back to the gps one if it gets enabled later? Does the system broadcast an intent when gps provider is enabled or disabled? Could I set up a listener for the same? public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } public void

I need to calculate the distance between GPS co-ordinates to calculate distance traveled. I've tried both the Haversine and Vincenty algorithms, which work fine on my desktop PC, but when I port the code to the dsPIC, they return 0 for points that are close (within several meters) due to a lack of floating point precision and poor implementations of sin and cos. For my use case, my points will be no more than 10 meters apart and will all fall within 10km of each other. I've tried the following algorithm and the results seem ok: double dist(double latA, double lonA, double latB, double lonB) {

This is my code. Please tell me y it is not able to calculate the distance.. In this code res is a long variable which is supposed to store the total distance covered. This code is supposed to calculate distance based on GPS as soon as there is a change in the latitude and longitude.. String serviceString = Context.LOCATION_SERVICE; LocationManager locationManager; locationManager= (LocationManager)getSystemService(serviceString); String provider = LocationManager.GPS_PROVIDER; final Location loc1=locationManager.getLastKnownLocation(provider); //Location loc1=new Location(""); String

I have an android application and I would like to obtain the location. For this I follow the android documentation, but it doesn't work. The onLocationChanged method is never called. public class GPSTestActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) { Toast.makeText(this, "GPS available", 3000).show(); } else { Toast
