Question Regarding Elevation Data in Grid Map #1

Description

@LihanChen2004

Thank you very much for your open-source work. Your extended_map_server and non_planar_obstacle_layer provide a more convenient approach to 2.5D navigation.

I have a few questions regarding this process. I am using octomap_server with pointcloud input, which successfully outputs the octomap. I then use grid_map_octomap to generate the grid map. However, I noticed that the output grid map does not include elevation data. Could you clarify what tools were used in your experiments to obtain the grid map?

I would greatly appreciate any insights you can provide!
