Error has occurred while running 'roslaunch hector_slam_launch tutorial.launch' about hector_slam HOT 4 CLOSED

Thank you for the report.
The geotiff launch files were moved to a separate package, looks like I've missed a reference.

from hector_slam.

If I am not mistaken the "geotiff_mapper.launch" was moved from the "hector_geotiff" package to the "hector_geotiff_launch" package. So in order to resolve this error you have to go to your "tutorial.launch" file and change the line
<include file="$(find hector_geotiff)/launch/geotiff_mapper.launch">
to
<include file="$(find hector_geotiff_launch)/launch/geotiff_mapper.launch">

Should be fixed by 77b51a6.
