Re: [sdw] WebVMT: inclide reference to MISB standards (#1120)

Good (and overdue) discussion of georeferenced video models / formats. One question it would be good to address is suitability, e.g. what are different approaches best suited for.

MISB KLV standards are really aimed at high resolution, high frame rate video streams where a single (or sometimes dual) stream is the most efficient approach but requires very specific software support that is not widely available (although better than it used to be, e.g. GStreamer). It’s not great, but here is an FAQ — http://www.gwg.nga.mil/misb/faq.html <http://www.gwg.nga.mil/misb/faq.html>

WebVMT’s linked model utilizes existing web discovery and transport mechanisms to facilitate sharing of video and where it was shot. Much more interoperable across existing information sharing platforms, but may be less suitable to real time streaming and/or texture mapping video than MISB.

There are pros and cons to both approaches, but it's particularly well-suited to web use and supports multiple media formats. I've also created an engagement site, since we last spoke (#1020 <https://github.com/w3c/sdw/issues/1020>), to provide a non-technical introduction to WebVMT at webvmt.org <https://webvmt.org/>, which may offer more insight and includes a few tech demos.
