[ros-users] SLAM precoding?

[Jason Byers]

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. Is the map file supposed to be located somewhere
else? Or am I making some kind of error?

Thanks for any help,
Jason
