Hi wcmc
I live in Medellin, Colombia.
I am in close contact with Gabriel Jaime Vanegas Montoya,
who is leading the balloon mapping project for local communities in
a difficult context of marginalization, violence and poverty.
He is giving workshops repeatedly on the matter, here's
a video of this work on youtube:
taken in and around the biblioteca piloto, a initiative of the
municipality, which installed public libraries in difficult areas of
the city, having tremendous impact.
I am happy to pass the contact along if this is of service to you.
As I just fond on the site Anita Chan has done some balloon mapping with indigenous communities in Peru. Does someone have her contact details?
