Using hector slam with amcl for localization in a pre-made map

I wanted to exploit the fact that hector_mapping gives pretty accurate position estimate. I used the position estimate to find odometry and now hector_mapping successful publishes the odom message and gives the required tf. But when I run amcl and publish an already created map using map_server everything messes up because now both the hector_mapping and
map_server are publishing maps. Even if I remap the hector mapping map to something else to divert it my tf is disturbed. Please help how to resolve this issue

Hi, just stumbled across your question. Might be a little late, but the following should allow to use both at the same time:

  • Remap the map topic of hector_mapping away
  • Set the pub_map_odom_transform parameter to "false"
  • If you want odometry published, set the pub_odometry parameter to "true"

Just came across this post and I'm trying to do the same thing. I can't find the parameter for where the map topic is being published by hector_mapping. I know its /map but not sure how to remap it somewhere else.

Maybe putting <remap from="map" to="maphector"/> in the launch file?
