Software gps track/trace

[Kroonen]

Most of the GSM have GPS on their device.

I should be possible to simply send the gps coordinates to your own site (database) (5 min interval) and those placed on a googlemaps?

Is there any software which does that??

So a client on Symbian (Nokia E71( that sends the coordiantes to an mysql database, with a query ge results and combine it with googlemaps

[Snelvuur]

for pocketpc's there is something called "trackme"

I have an e71 too and also would really like to have this option.
But an MYSQL whatever is already too complicated for me...

Trackme works great (trip loaded in Google Earth):

Trackme is great, they even have advanced PHP server to log to your own server.
I use trackme also and made a server program for it in classic ASP.
check also the latest topics on http://www.domoticaforum.eu/topic.asp?TOPIC_ID=616

I have written a trackme client for my Android G1 dev phone.
and build the server side in DomotiGa's webclient, still work in progress.

Pieter, where do you get your reverse geocode data from?

sendString = geoLat & "," & geoLong
strURL = "http://maps.google.com/maps/geo?output=xml&oe=utf-8&ll=" & sendString & "&key=$key"
This gives an XML file back from google, very easy!

I have used this script to test the functionality.

Works ok!

Code: Select all

<?php

   // Your Google Maps API key
   $key = "YOUR_KEY_HERE";

   // Connect to the MySQL database
   $conn = mysql_connect("localhost", "user", "password");

   // Select the database
   $db = mysql_select_db("trackme");

   // Query the table
   $query = "SELECT Latitude, Longitude FROM positions";
   $result = mysql_query($query) or die(mysql_error());

   // Loop through each row, submit HTTP request, output coordinates
   while (list( $Latitude, $Longitude) = mysql_fetch_row($result))
   {
      $mapaddress = urlencode("$Latitude $Longitude");

      // Desired address
      $url = "http://maps.google.com/maps/geo?q=$Latitude,$Longitude&output=xml&oe=utf8&sensor=false&key=$key";
      // Retrieve the URL contents
      $page = file_get_contents($url);

      // Parse the returned XML file
      $xml = new SimpleXMLElement($page);

      // Parse the coordinate string
      list($Address) = $xml->Response->Placemark->address;

      // Output the coordinates and first address received
      echo "\"$Longitude\",\"$Latitude\",\"$Address\"<br />";
   }
?>

Thanks and Regards,
Ron

Mooi he
Great functionality of google!
I get the address as soon as the data (lat long) is coming in on my server.
So I receive the the GPS data of my cell phone and while I store this in my database I use the google web service for reverse Geocoding, all at once and therefore real-time.
As I can see you are not doing this realtime?

@RDNZL
I think that Google willnot be very happy when you send them a request for all positions that you retrieve in your query to the positions table!! (Or I do not understand the php stuff )

[Bwired]

You can retrieve with 1 key like 10.000 addresses a day.

@dutchnomad:
I have been testing a lot the last days... I didn't hear google complaining
They didn't made that API for nothing... ok if you are a company or have 10000's of queries, they want you to contact them they say, to make a special arrangement I guess

@Bwired:
Yes I do it realtime, this was only a test routine... to see if it is giving results that I can live with

[dutchnomad]

Oke that is no problem for Google I suppose, however I wonder what would be a reason todo the query for all points? since TrackMe (I use it already for a long time and use the php server on my onw server) works with trips I can imagine that you determine the address of the starting point and the end point of the trip.
Besides that It would be nice to do an address lookup at request, based on 1 specific lat/lon combination.

But it is fun stuff!
