Is there any way to pinpoint the visitor's exact location?
Yes. You ask them to fill in a shipping address. They may still lie,
or they may choose to not answer, but that's the best you're going to
achieve without getting a wizard to cast Scrying.
No, no registration requirements.
you know when i go to maps.google.com its always find my exact city of location
and not just say Europe/Athens.
and twitter and facebook too both of them pinpoint my _exact_ location.
How are they able to do it? We need the same way.
They use client-side JavaScript. This is a relatively new API available in most,
but not all, recent browsers. This information will not be available to your CGI
script. You will have to generate HTML with the proper JavaScript to get the
geolocation (if the user allows it) and then send it back to your server through
a different CGI script (or web application endpoint).
