Hi there, Because of the mapping we are doing in the states affected by flooding in northeastern Brazil, we had direct contact with INPE, and we were informed that the satellite images of the CBERS 2B HRC can be used to perform mapping in OpenStreetMap.
The images cover the whole South America in a resolution of 2.7m, black and white, and are extremely useful to map locations out of large cities. The big problem is that these images are not geo-referenced, so I'm wondering if we can setup a web-service to crowdsource this work, based on gps tracks and other satellite imagery. The image catalog can be accessed here: http://www.dgi.inpe.br/CDSR/ Vitor
