Right now there are two sets of images that cover Jacmel, the DigitalGlobe data from last week and the JAXA/ALOS satellite imagery. As far as I know, most of or all of the satellite imagery we have access to now isn't very well georeferenced so you may need to adjust the image to get a "rough" fit before doing any corrections and/or traces. You can see what we know about by checking out the following relation: http://www.openstreetmap.org/?relation=388801 and this Wiki page: http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/Imagery_and_data_sources There is some new data from both Digital Globe and GeoEye being imported so check the wiki page for updates. -- Jeff Ollie _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
