In addition to covering the challenges of augmented reality
applications, it details among other things the WFS extension we
developed for making requests for 3D data such as referenced and
positioned 3D buildings, as well as the E3D compact 3D model format and
a revision of the GNOSIS Map Tile standard to support referenced or
embedded 3D models as well as point clouds. I would also be happy to
talk a bit about this if there is time and interest.
