Hello and thank you for your answer, I didn't took time to look at your profile and I found the URL to use for this area.

But I'm affraid that it could be filtered outside of Colombia: I'm getting timeout from mapas2.igac.gov.co, still today.

You made a great work of documentation on wiki about Colombia and it's nice to read, thank you.

Regarding power comanies, we are not set to assign accurately operators for now, we only seek for missing power lines and substations on well known aerial imagery. I will took time to write a little on the community forum about what we found so far.

All the best !
