I am testing the results of Lidar to Raster with 0.5m resolution with ArcGIS 10.3.1 SAGA-GIS and Grass 7. My LAS File consists of regular spaced points with a 0,5m resolution. No coordinate transformation took place. The resulting rasters are shown in the screenshots below. I created the LAS Dataset in ArcGIS by right clicking in the Catalog window in ArcGIS >New>Las Dataset. The Tool LAS-Dataset in Raster was used to produce the raster. The ArcGIS Raster cells are shifted and do not center on the point data from the lidar. The rasters created in Grass-GIS by running r.in.lidar > Export to raster or with SAGA-GIS using the workflow lidar to Pointcloud - Pointcloud to Grid > Export Grid to GTIF both create cells whose center is the lidar point.
Can anyone explain this difference and whether it has an negative effect on the validity of the resulting dataset?
