DGGAL DGGRS Provider

The DGGRS provider DGGALProvider uses dggal 0.0.5 to generate various DGGRS. The current implementation supports the following grids:

  • ISEA7H_Z7

  • IVEA7H

  • rHEALPix

  • HEALPix

Initialisation parameters

The initialisation parameters dictionary: parameters in the dggrs table provides which grid the instance is going to support.

Users can specify the grid in the parameters by the keyword grid. The grid names are case insensitive. For example:

Define the ivea7h grid
     "dggrs": {"1":
         {"ivea7h":
             {"title": "IVEA7H DGGRS provided by dggal",
              "description": "An equal area hexagonal grid with a refinement ratio of 7 defined in the IVEA projection, using the same global indexing and sub-zone ordering as for ISEA7H",
              "crs": "wgs84",
              "shapeType": "hexagon",
              "definition_link": "https://dggal.org/",
