Title: COPC .laz support for exporting point cloud
Post by: spader on April 13, 2022, 12:17:28 PM
There is a push in the open source community for a new, backwards-compatible way of formatting tiled .laz files called COPC. The result is a single laz file that can be streamed/has LOD etc etc, which previously were restricted to potree/entwine exports which consists of thousands of files. At the same time it can be opened using all the standard laz reading methods, as it is "just a laz", in a manner similar to a cloud optimized geotiff is "just a tiff".

If Metashape would add support for exporting point clouds directly this would be really beneficial, since this would significantly reduce the overhead of using/showing others the billion-points large point clouds we routinely produce.

QGIS will support simple drag-and-drop copc laz in 3.26, and potree 2.0 will support copc as well. PDAL supports reading/writing copc as of 2.4.0. I am not sure about Cloudcompare, but I hope it will support copc.
