[talk-pr] Imagery and Government Data for PR

Fri Jan 17 02:26:02 UTC 2014

Good, whichever method would be best I'm for it. I'm definitely sure the
2006-07 imagery is public and finding that documentation should be easy. I
will have to look for the documentation on the 2009-10 imagery, ideally
before any efforts to start using it. I've seen the 2009-10 imagery weigh
25GB in ".sid" format and 50GB in ".gdb" ESRI format.

Hi José, nice to meet another OSM enthusiast. I don't recall hearing any
specific reason why CRIM's buildings dataset is not available for public
use. It would be great to have a specific answer, at least with the
buildings layer. Buildings is something we could draw (with lots of time),
but it would be great to have height information, even rough numbers
gathered from LIDAR. Hey and thanks for reaching out to key people on the
government.
