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

“HIGHLIGHTS:
• Hexagonal multi-structural elements enhance Earth's surface modeling precision.
• Integration of indexing and conversion rules improves geospatial data computation.
• DGGRID implementation shows increased precision in raster and vector data modeling.
• Addresses limitations in existing software for Earth observation data.
• Pioneering approach expands geospatial data processing applications…"

Luís 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 😀
