I had an idea for a cool mashup that included a map , countries coordinates and another secret ingredient. But to my surprise, I couldn't find a free Country to gps coordinates Database. which means that even though Columbus discovered America more than 5 centuries ago there are still some uncharted lands in the virtual world.

Sure, there are some interesting GPS information Databases about Airports , Hotels and other special interests but I just couldn't find a very basic type of I'll give you the country name and I'll get a GPS coordinates (somewhere in the middle of the country) in return.

So I've started this wikipedia page, it is basically just a list of countries and an empty place to enter a longitude, latitude coordinates.

How can you help you ask ? One simple way is to go to any maps services such as Google maps or Live's maps service, zoom in to a center location of your favorite country, extract the GPS coordinates of that point and paste them in the wikipedia page for all to use freely .

Here is a very short tutorial on how to extract the coordinates from Google maps , the same similar technic can be used for Live's maps service as well

3 states are already tagged with their coordinates, just 254 to go !
let's see how long it takes for the whole list to get completely filled with would countries coordinates.

In one of my previous posts , I provided an example of embedding GPS coordinates into a JPEG image. I had a bug!. It only took care of the eastern side of the world.
A comment by John about not working with negative longitude numbers identified the issue, thanks John!.
Well, watching the Olympics , and the concept of living in a global village have motivated me to sit down and fix my code so all of you people on the left side of the prime meridian can embed you Geo location in your Jpegs as well.
