I too took that understanding from the text, Ari. I'll read the specs later, but since they mention a lot Big Data and the raster <> vector integration, I imagine it is akin to a geometry collection, but encompassing a wider range of data types, and arranged in a pyramid/r-tree -esque environment for faster processing.
If so, it's not an entirely novel idea (Esri's File GDB is mostly that, as well as the entire CAD modelling), but one that would be interesting to have an open standard for. 2017/10/31 午前4:23 "Ari Jolma" <ari.jo...@gmail.com>: > That also caught my eye.
