58 | | * G72:r.in.lidar - base_raster option which allows for the conversion to LAS file Z values to height above ground using an existing elevation raster, -j option which allows the use of Z values for filtering of points, yet performs statistical analysis on the intensity values |
| 58 | * G72:r.in.lidar |
| 59 | * base_raster option which allows for the conversion to LAS file Z values to height above ground using an existing elevation raster. Additionally, with -d a base_raster is used in its native resolution to enable performing statistics on with coarse resolution while reducing the heights of point using the base_raster in its full resolution. |
| 60 | * -j option which allows the use of Z values for filtering of points, yet performs statistical analysis on the intensity values |
| 61 | * intensity_range and intensity_scale to filter and modify intensity values |
| 62 | * significant documentation improvements |
| 63 | * file option to specify list of files (file paths) in a text file (merges multiple LAS files on input as if it would be one file) |
| 64 | * -n flag to set region according to the newly created raster (useful with -e flag) |
| 65 | * bug fix for low memory processing option |
| 66 | * bug fix for extremely large rasters |
| 67 | * -v to import use only valid points. This is a change of behavior. Previously, invalid points were always ignored. The behavior was removed because of unclear definition of invalid point in libLAS library. No invalid points are filtered out only when requested which makes it consistent with other filters. However, if invalid points are present, user gets a warning message. |
| 68 | * G72:v.in.lidar |
| 69 | * id_layer, return_layer, class_layer, rgb_layer to store point attributes as layers and categories |
| 70 | * point cloud decimation (skip, preserve) and subset import (offset, limit) |
| 71 | * vector mask to limit import to given areas (mask, mask_layer, -i for mask inversion) |
| 72 | * -c flag to not add unique IDs as category to each point. More points than the category number limit can be imported. This also requires less space on disk and time during import. |
| 73 | * general improvements to handle large amounts of points |
| 74 | * zrange option to filter out points based on height |
| 75 | * -v to use only valid points. This is a change of behavior. Previously, invalid points were always ignored. The behavior was removed because of unclear definition of invalid point in libLAS library. No invalid points are filtered out only when requested which makes it consistent with other filters. However, if invalid points are present, user gets a warning message. |
