grid-scaled point cloud

A point cloud in which the distance between any two points is the same distance that you would obtain if you inversed between them. The Inverse command measures grid distances in a specific coordinate system and therefore takes into account all of the distortions associated with the coordinate system’s projection. A grid-scaled point cloud is stretched or compressed when compared to a ground-scaled point cloud. Because the scale factor depends on both the horizontal position and vertical position, the degree of stretching and compressing is position-dependent. Most photogrammetry software packages create point clouds this way because they use grid positions for camera and/or ground control points (GCPs); such point clouds are typically also georeferenced (not near 0,0,0).
