It could also convert .ecw to geotiff or some other more common format. All the options for dealing with a large imagery involve setting up a server to host it. If you're able to grant the necessary permissions you might be able to get someone in the community to host it. I know Grant Slater hosts AGRI imagery for Australia. ___ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev
Re: [josm-dev] Adding your own imagery
HI, Thank you very much for everyones help, I was able to take simon advice and convert the ecw file to jpeg with a worldfile and import it in using the importimageplugin. I did have to up the JOSM memory to do this, following the instructions on http://wiki.openstreetmap.org/wiki/JOSM/Mac Thanks to Simon, Paul and Russ in replying to me!
