The OGC and ASTM are discussing the possible synergy of working together on the following announcement:
The Open Geospatial Consortium (OGC) has established a Point Cloud Domain Working Group to assess the current state of standards and best practices in the management of point cloud data and to guide OGC activities in working with or developing standards for point cloud data interoperability, discovery, and dissemination. Details on the Point Cloud Domain Working Group can be found at: http://www.opengeospatial.org/projects/groups/pointclouddwg. Interested parties can join the e-mail list at: https://lists.opengeospatial.org/mailman/listinfo/pointcloud.dwg.
I hope some of you will join as this is an excellent opportunity to take advantage of the standards work being done by these leading orgs.
