Am I reinventing the wheel on this idea?

Question

Ok here it goes, hope this is an original idea. Scenario is this. I have hosted a personal website, which contains a wordpress blog as well. I have a windows mobile connected to internet via GPRS.

I want to write an application for my windows mobile, which would track my current GPS coordinates (I don't have GPS but have figured out a way to find out the coordinates), and upload them to my site, where I'd provide a web service which can get or set GPS coordinates. Then I want to display my current location in my blog (as a wordpress plugin) or in another page, where it talks with my web service again to obtain my latest GPS coordinates.

So am I reinventing the wheel or there's a complete solution available for me to achieve such a thing?

Any pointers please. It's not directly programming related, but it sure involves programming!!!

Answer 1

Sounds like Google Latitude.

Answer 2

There are quite few of these types of applications/systems.
I myself have written a similar system to try to recover my phone if it gets stolen.
On codeplex you can find This (not mine).
