Adding data points to grid map

[Jeromelee95]

Hi,

I am trying to input data of position and elevation recorded from my robot into the grid_map package. The output I am trying to achieve will be a 3d map. I have already written the subscriber portion to subscribe to the sensor topics. However, I do not know how to assign the data from the sensor topics to the point on the map. Can anyone advice me how to carry on?

Thanks for your time!

Hi @Jeromelee95, isn't elevation_mapping doing what you want?

Hi @maximilianwulf, thanks for your reply. i dont really understand how elevation_mapping work. Could you guide me through how to work with it? I have only tried to work with the demo but there are errors running it

Hi @Jeromelee95, unfortunately I cannot guide you step by step. But the underlying documentation of elevation map is very descriptive. Have a read here.
