Hello Everyone
This is not a programming question but am looking for an Android App.
An app where I can enter lat lon or address and a compass will point me to that position. It does not need any navigation. Just an as the crow flies direction pointer.

Thanks much ...

I am working on a project that tracks multiple vehicle, golf carts, bikes and people at the same time ... I know I can buy system but I have to build this myself .... Im designing the REST API to accept the data and put it in the database ... every 10 sec I iterate through the database using the latest timestamp.... The question I don't want to built GPS trackers(Ardrino) ... does anyone know of a fully programable tracker for sale on the market that I can program to send data to my site (gps data) ...thanks in advance

I have created the following two functions inside my JS file (which will be used in PhoneGap/Cordova) and I have put them outside of the main JavaScript class:

**
 *@description Returns the latitude of the current location
 *@return {float} a latitude
 */
function getLatitude() {
  return position.coords.latitude;
}

/**
 *@description Returns the longitude of the current location
 @return {float} a longitude
 */
function getLongitude() {
  return position.coords.longitude;
}

Why is it, that if I put this into my HTML page, I can get the coordinates - but when I call these functions from within JavaScript, I get an error saying that position is undefined?

What is a workaround so that I only get a latitude or longitude?

I am developing my first application with Apache Cordova and I need some assistanstance with the Open Street Map object. I am sending a request to the Open Street Map to get Lat/Lng of a location. I chose Manchester UK and I received the following JSON back:


In order to do this, I set to share a taxi (it's a taxi sharing app) first and then I click on Update Map.
This is the code for UpdateMap:

     function updateMap(address){
        var onSuccess = function(position) {
          var div = document.getElementById("map_canvas");
          div.width = window.innerWidth - 20;
          div.height = window.innerHeight * 0.8 - 40;
          // change the zoomin level
          map.setZoom(15);
          if (address != undefined) {
            // TODO 2(a) FR2.2
            var endPoint = "https://nominatim.openstreetmap.org/search/" + address + "?format=json&countrycode=gb"
            $.get(endPoint,function(e) {[embed=file 1418190][embed=file 1418191][embed=file 1418192]
              var location = e;
              map.setCenter({
                lng: location.lng,
                lat: location.lat
              });
            })


          } else {
            map.setCenter({
              lng: position.coords.longitude,
              lat: position.coords.latitude
            });
          }
        };
        var onError = function(error) {
          alert(
            "code: " + error.code + "\n" + "message:

Does anyone know if there is a place to get a FREE XLS, CSV or other file format that will allow me to get Countries (US or North America is fine) States & Counties so that I can link it up to some data I have.

If I could get States, Counties, Cities, Zip Codes, Latitude & Longitude even better. I have been to Data.gov, US Census but not really seen a clean or relatively clean set of data that would help me with a project. Does anyone know where I can get that? Please advise. Thank you.

What FREE Android Phone tracking location AT&T APP do you recommend so I can find where my child is currently at if needed ?

 2. etc ?

How can I indicate to my iPhone X that I am walking (and not driving) while I am using the built-in GPS map services to provide me with turn by turn directions?

This is especially important since I visit a lot of towns that have one-way streets.

My Galaxy Note 4 (already updated to latest Android) tends to lose
connectivity to GPS (even though the connection to cellular/mobile
data network seems to be intact) while driving for 3 to 30 secs.

I'm using Waze.  The disconnection can happen even on a bright
sunny day (ie don't have to be cloudy/rainy days) or in open
highway (ie not while going through tunnels).

The same SIM card was previously used on my Galaxy Note 2 for
for almost a whole year previously & I never had this issue.

Is this a known issue with Note 4 or the Telco ?  Maybe one way I
can test this is to use the Note 4 as a hotspot (tethering) to an
iPhone & test to see if Waze/GPS  disconnects intermittently:
map is still there but there's a red alert message that 'connection
to GPS is disconnected' at the top of the screen.

I only noted 2 changes:
1. I switch from Note 2 to Note 4 at around the time I disposed
    the old Honda Airwave to Toyota Sienta hybrid: not sure if
    there's something in Sienta that interferes
2. Note4 tends to get very heated up while Note2 is not that
    hot while Waze is in use: I've since taken out the backcover
    of the Note4 (& used scotch tapes to hold the battery & SIM
    card in place) when in use so that the heat dissipates

Plotting Photos on a Map

I have pictures from an iPhone6, iPhone 7 and a Canon PowerShot.

I know the iPhone 7 photos have the geo coding embedded. But I need to verify the Canon Power Shot is working for geo coding.

And if not, I may buy a new camera for myself.

And how do I view a folder of image and plot them all on a map?

Thanks

There a lots of gps apps, but usually they are more for cars & vehicles.  We are looking for one that can we can find each other within a mall or a department store.  Any EE knows of any good ones?
