GEOV file format — symbology

For users exchanging .geov with QGIS or other tools: how layer colours and classes are stored in project.json (miniGISimple-symbology-v1).

Placement

Each object in layers[] may include:

  • style (required for interoperability): single-symbol paint and shared layer paint. Used when symbology is absent or type is "single", and for non-color paint when classified symbology is active.
  • symbology (optional): categorized or graduated rules.

provenance.symbologySchema may be "miniGISimple-symbology-v1" when any layer exports symbology.

Export should include materialized categories or breaks + classColors so consumers can render without re-classifying.

Rendering

  • Categorized: MapLibre match on to-string(get(field)).
  • Graduated: MapLibre step on to-number(get(field)).

Colors apply to fill, line, and circle paint where the geometry type allows.
