Cannot determine map extends in hector_mapping and hector_geotiff [closed]

edit

Hello,

I'm trying making map with hector_slam and Hokuyo LRF modifying the tutorial. I can see map developing on rviz (/scan frame on Fixed Frame /map). But when I publish 'rostopic pub syscommand std_msgs/String "savegeotiff"', I cannot get any maps with error;

[ INFO] [1438081626.473636531]: HectorSM sysMsgCallback, msg contents: savegeotiff
[ INFO] [1438081626.475337758]: HectorSM Map service called
[ INFO] [1438081626.492065364]: GeotiffNode: Map service called successfully
[ INFO] [1438081626.499347522]: Cannot determine map extends!
[ INFO] [1438081626.499403181]: Couldn't set map transform

I cannot find out why this error occur though I'm trying to understand the source. I'd appreciate any help. Thank you.

This is full message on the console
