Combining the elevation maps into one larger map

[valli96]

I am attempting to do a path planning through an uneven terrain. For that, I wanted to use this project here. I had thought that I could somehow link the resulting elevation map as I move around, but as I understand the project is not able to do that #183

A suggestion from another problem was to enlarge the buffer so that I can fit the whole map in it. Are there any other possibilities there?

In the end, I wanted to have an occupancy grid map, which I wanted to create with some information from the elevation map.

Is this elevation_mapping-project what I am looking for? I didn't quite get that from the description or from the other problem I looked at.

@valli96 did you find a way to implement this and get a "global" map of elevation? either in terms of a global grid map or a global occupancy grid (which would be the easier option as there are ways to stitch and expand to a global 2D occupancy grid already) @heuristicus @maximilianwulf is there a way to create a grid map of dynamic size so that it could be updated to a grid map with global information? (expand as the mapping procedure is running) Or i should start thinking of another data structures for such implementation ? Thank you very much in advance!
