[support] Geotagging and GIS in Drupal?

[dondi_2006]

Hello,

another thing I'd need from Drupal is Geotagging support, that
is the ability to categorize and search content based on location:

"This node is associated these coordinates"

"List all relevant nodes associated to places maximum 100 miles
from my home"

I've seen with Google there is a location module. I'll study it,
but any feedback, code example, URLs of Drupal sites already
doing this etc are greatly appreciated.

TIA,

Ortles
