Hi @Pyy666666,
Elevation mapping works in a simulated environment, like replaying a bagfile with use_sim_time enabled.
The time stamps indicate a difference of approximately 2 years. Can you show the timestamps of your pose and point cloud messages?

Hello @maximilianwulf , I have a similar question. When I was running my rosbag, it shows the error message that
[ERROR] [1630035157.105520959]: Could not get pose information from robot for time 1629766049.504058. Buffer empty?
By debugging, I found that the error is from boost::shared_ptr<geometry_msgs::PoseWithCovarianceStamped const> poseMessage = robotPoseCache_.getElemBeforeTime(lastPointCloudUpdateTime_); in ElevationMapping.cpp. The poseMessage is 0 or empty. How can I fix this issue?

@StevenHong did you set use_sim_time to true?

Closing this because the culprit is most likely a wrong setting. Feel free to re-open if further assistance is required.
