Reconsider GeoAlignment based on XR- industry and standards development progress #9

Hi,

The Open Geospatial Consortium has announced a request for public comment on a 6DOF GeoPose standard that might become an official universal encoding standard (currently describing a JSON encoding) for the real world position and orientation of any real or digital 3d object in a gespatial frame of reference. Request for Public Comment on GeoPose draft specification

Also all the big tech companies are talking about AR-Cloud or Metaverse based future platforms that will fuse the digital world and the real world togeather in new and interesting ways.

Both big and small companies are doing work on (AR-cloud based) services that allows an AR device to relocalize to a real world pose, with far greater accuracy than what is possible with GPS, inertial and geomagnetic sensors on the device. Here is a list of some of them:

Augmented City, Immersal, ARWAY, Augmented Pixels, Sturfee, Sensetime, Neogoma, Fantasmo, Apple GeoAnchor, Niantic (Scape.io), Google VPS, Google Cloud Anchors, Facebook VPS (6d.ai), Azure Spatial Anchors

Then the Open AR Cloud Association is proposing for our Open Spatial Computing Platform (OSCP) a GeoPose Servie Protocol (based on OGC's GeoPose encoding standard) for how you can make a standardized request to a service endpoint where you provide some sensor data and you receive an estimate of your device GeoPose.

Theese developments points to an opporutunity to make the Web platform the primary way to experience the Spatial Web or the Metaverse if it could only speak to such spatial computing services and understand what they serve.

This might be achieved by thinking of "AR Cloud" services as something that could be seen as a "virtual device sensor" but where the sensor readings are not originating form electronics on the device but rather from an external service that the device has a connection to.

Any thoughts? @blairmacintyre?

The key abstraction that relates these is coordinate reference systems, and the open source software that implements them in the GeoWeb. If we can bring the CRS / open geospatial web, and Web platform software worlds together, we will be able to achieve geo-alignment, and more, I hope.

Over in the Maps for HTML Community Group, we are specifying and polyfilling 2D CRS support for the Web, and it would be great to pull together with the immersive web community to achieve more than the sum of our individual efforts.

Bump, personally I'm struggling to see the use case for AR without any real world geospatial reference this plus the underlying capability to do cloud/synced anchors is key to building immersive and engaging AR experiences.
