Load and visualise GeoZarr-compliant Zarr stores, including Icechunk repositories and their multiscale pyramids.
Adds a raster data provider for GeoZarr datacubes. Reads directly from Icechunk
repositories (local, S3, GCS, Azure, R2 or HTTP) as well as plain Zarr v3 stores,
resolves the CRS from zarr-conventions "proj:code" or CF grid mappings, and switches
between pyramid levels as you zoom. Icechunk branches, tags and snapshots can be
selected at load time and changed afterwards without re-adding the layer.
.
ONE MANUAL STEP AFTER INSTALL: this plugin needs the "zarr" (>=3) Python package,
and QGIS's Plugin Manager does not install Python packages. After installing,
open Raster > GeoZarr Viewer > Install Python Dependencies... - it detects your
operating system and QGIS build and shows the exact command to run, where to run
it, and the interpreter it targets. "icechunk" is optional and only needed for
Icechunk repositories; plain Zarr v3 stores work without it. Both require Python
3.12 or newer, which means QGIS 3.40 or newer.
