How can I get the costmap of elevation_map from the topic?

Thanks for your excellent work!

I have run the demo successfully. I'd like to ask is there any directly way that I could get the costmap from the elevation map's topic?

Looking forward to your reply. Thanks a lot.

I had been looking for this as well and I guess there's no option but to implement your own costmap plugin. You can find an excellent example in the PR (Pull Request Section) #84 . Hope this helps.

Hi @SUN-GE, @usamex is right, at the moment the package does not support costmaps. The grid_map package provides functionalities to convert height maps to costmaps, see here.

For the moment, you will have to implement this feature by yourself. We do not plan to integrate it.
