I don't think `elevation_layer` is a good name for this package. Since it's a plugin for costmap_2d, this should be somehow clear. What are the names of other costmap_2d plugins?

@LZMHIT Did you make sure to build in "Release"? Although the elevation mapping was originally developed for a robot-centric formulation, you can also associate the map to a static frame...

Dear @mjschuster, thanks a lot! This might actually be an issue and I can look into this at a later point. If you have a suggestion on how to implement...

Thanks, @ThomasEmter! I merged your PR and extended it with other places where this code had fixed-size Eigen members. Let me know if we need to work more on this...

Hi @artivis, thanks for sharing! I agree, a resizing method which is easier to use then `extendToInclude` could be implemented. Internally, the `extendToInclude` could call this resizing method. How would...

Hi Alice, Thanks for reporting this behavior. You are right, I have not taken this special case into consideration since we’ve never run into this issue. I you have a...

Hi @nitin5, Do you mean inflating similar to what can be done for [costmap_2d](http://wiki.ros.org/costmap_2d)? You could achieve a similar effect by converting the grid map layer to an OpenCV image...

Thanks for reporting this! We have a [unit test](https://github.com/ethz-asl/grid_map/blob/master/grid_map_core/test/LineIteratorTest.cpp#L74) for the case where both start and end point are outside the map, so I'm unsure what happens in your case....

Excellent idea, @ammarhusain! I don't have the capacity to work on this right now, but I'm happy to work with anybody who wants to implement this feature.
