#1480: v.outlier - distinguish positive and negative outlier filtering from lidar point clouds -------------------------+-------------------------------------------------- Reporter: sbl | Owner: grass-dev@… Type: enhancement | Status: new Priority: normal | Milestone: 6.4.2 Component: Vector | Version: svn-develbranch6 Keywords: review | Platform: All Cpu: All | -------------------------+--------------------------------------------------
Comment(by mmetz): `v.outlier` is not designed to separate first from last return of LiDAR point clouds. The purpose of `v.outlier` is to detect true outliers, i.e. erroneous data points. First and last returns are not erroneous data points but valid data points. First and last returns can be separated with the LiDAR filtering toolchain `v.lidar.*`, `r.in.xyz`, and in grass 7 `v.in.lidar` and `r.in.lidar`.
