GPS Questions

[goehberry]

Hi Guys,

Is it possible in b4a to create track several devices (android devices that equipped with GPS) location and show it realtime on google maps or similar maps?

Please share your experience or solution will be greatly appreciated.

Thanks

This is actually not a GPS question, as each device which has a GPS reciever can show its own position on a map. How to do it is detailed in the GPS library and many other examples. If you want to show several devices position you need to communicate the positions of all devices participating to the one showing the map.
The "simplest" solution is a server site that keeps a list or database and the devices call this site and download the data.

Hi David,

Thanks for your reply. Are you suggesting that on each devices there is a code that send the device coordinate to a remote server, and then at that remote server visualizes on google maps? Are there link or resources that can help me get started?

Thanks in advance!

Here's a package that might help: GPS Tracking: Open-Source GPS Tracking System - OpenGTS & Where Is It? - Tracking vehicles with OpenGTS - Linux Magazine.

I haven't used OpenGTS myself, it's something i bookmarked for a future project.
