Hello, The scenario is: the user opens a large Lidar file, changes the classification labels of a small number of points and save the changes to the file. When the Lidar file is huge, it is time-consuming to output all the points. So it would be better if only the modified points are updated in the Lidar file. According to my understanding now, Liblas needs to save all the (changed and unchanged) points to a new Lidar file. That's because Liblas can open a Lidar file either in read-only mode or write-only mode, but not in read-write mode.
Do I understand correctly? Is there a way to only update some points? Thanks a lot, Hongwei Shen Software Engineer, ERDAS, Intergraph _______________________________________________ Liblas-devel mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/liblas-devel
