GM_LidarClassifyGround – Global Mapper

Global Mapper SDK

Automatically identifies ground returns from the points in the specified loaded Lidar layer(s). If you want to only classify a subset of the points in a cloud, first use GM_CreateLidarQuery to build a set of the points that you want to classify, then use GM_LidarClassifyGroundFromQuery to do the classification.
