Two things to try, in particular: * start rviz and check that it visualizes the map correctly * use map_server/map_saver to retrieve and save the map as a bitmap I've never tried loading an .xcf file; there's some chance that map_server/map_server won't read that format correctly. On Linux, .png is definitely supported. brian. > On Thu, Mar 24, 2011 at 7:35 PM, Jason Byers wrote: >> >> Ok so I drew up the map to scale using the GIMP image editor, and created >> the YAML file named map.yaml, and ran the command line >> >> rosrun map_server map_server map.yaml >> >> after running roscore in a separate terminal but it just sits idle saying >> >> [ INFO] [1301019197.508222505]: Loading map from image >> "./riggs_basement_metric.xcf" >> >> and my map's name is riggs_basement_metric.xcf and is in the same package >> folder as the yaml file.
