Alexander KmochJustus made a great intro on using #DGGS through #xarray #xdggs at the #Pangeo showcase talk. Xdggs is now in a stage where you can use it fairly robustly with #HEALPIX and #H3. Other integrations like for #DGGRID are developed as separate plugins.

Dggrid | http://Anaconda.org You can now install #DGGRID on Apple Silicon/ osx-arm64 architecture. I also managed to update to the stable 8.1 version. DGGRID version 8.3 with exciting news features and indexing systems will land soon too #DGGS #geospatial #grid https://anaconda.org/conda-forge/dggrid

[the math is way over my head, hence the wiki page leak, but a good read nonetheless]
βHIGHLIGHTS:
β’ Hexagonal multi-structural elements enhance Earth's surface modeling precision.
β’ Integration of indexing and conversion rules improves geospatial data computation.
β’ DGGRID implementation shows increased precision in raster and vector data modeling.
β’ Addresses limitations in existing software for Earth observation data.
β’ Pioneering approach expands geospatial data processing applicationsβ¦"

LuΓs de SousaJust found out that Kevin Shar opened a repository at GitHub last summer for the #DGGRID software. It is now at version 7, with support for aperture 7 with hexagons. I am going to have some fun during the Christmas holiday π
