[Liblas-devel] Can Liblas only update a small portion of the points in Lidar file?

[Martin Isenburg]

Hi,

Make sure you disable the feature when the file is laszipped. There is
*no* way to add this. However, we could - in theory - support the
appending of points to an exsiting LAZ file.

cheers,

martin
