For anyone collecting, processing or otherwise working with point cloud data this may be worth tracking.

Subject: [TC-Announce] e-mail vote: Point Cloud DWG charter

Dear Technical Committee,

This is a notification of an e-mail vote for creation of the Point Cloud Domain Working Group (DWG).  The Point Cloud DWG is being established to address the gap in the OGC standards baseline with regards to point cloud data.  Although this group will not be the platform for creating new standards, it will be the platform to discuss and understand any issues, concerns, or barriers to interoperability for the point cloud community.

This charter represents an acknowledgment of the gap in the current OGC baseline regarding standardization of point cloud data and service formats. This working group is motivated by the fast growing popularity and use of point cloud technology.   This includes a number of formats and types such as: laser scans from aerial and terrestrial platforms (e.g., LiDAR), triangulated elevation points, dense observations from the meteorological community, and others.  Based on these considerations this charter defines the OGC Point Cloud Domain Working Group (DWG). 

OGC has a number of Working Groups to discuss issues relating to services, domain communities, and various data formats.  However, point cloud data has often been overlooked or treated in the same buckets as images or terrain. Today the use of point clouds is growing at a rapid rate and can be found in a variety of domains including utilities, mining, 3D modeling, etc. Point cloud data is currently stored in many formats, some now de facto standards, defined for many domains such as Multi-dimensional Scientific data, LiDAR data, Elevation data, Seismic data, Bathymetric data, Meteorological data, and Fixed/Mobile consumer sensors (IoT).  With so many uses of point cloud data but little standardization, a variety of different formats exist.  OGC membership has registered a concern that without development of Best Practices or consensus standards, divergence will continue in the community and interoperability will be inhibited

As an example, LiDAR data is most commonly exchanged using an ASPRS standard format known as LAS. However, end-user consumption of LAS content for analysis or display requires indexing, optimization and/or compression of the content, with multiple methods available ranging from vendor-specific indexing schemes to commercial and free optimization and compression toolsets.  Further, more capable LiDAR encoding formats are being developed in specialized communities, such as the Sensor Independent Point Cloud (SIPC) based on HDF5.

OGC membership is not necessarily advocating creation of a single point cloud encoding standard, rather the members have expressed interest in ensuring greater interoperability between point cloud datasets and identifying methods to integrate such data to interoperate with other OGC standards.

The charter can be found here:

Please provide comments or objections to the TC Chair (me) by 3 July 2015.  If no objections are raised by 3 July 2015 then this DWG will be considered to be officially approved and will commence work.

Thanks and Regards,
Scott
