Datacube Viewer
Load and visualise datacubes from GeoZarr, Zarr, NetCDF and Icechunk, with multiscale pyramids and sliders for time and other axes.
Load GeoZarr datacubes, plain Zarr stores, NetCDF files and Icechunk repositories
as raster layers in QGIS.
Sliders in a dock panel step through the non-spatial axes of the cube (time, sensor,
etc.) and redraw the layer as you drag. The plugin reads directly from
plain Zarr v3 stores and NetCDF files as well as Icechunk repositories (local, S3,
GCS, Azure, R2 or HTTP), 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
for Zarr stores and/or "netCDF4" for NetCDF files, and QGIS's Plugin Manager does
not install Python packages. After installing, open Raster > Datacube 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. zarr
and icechunk require Python 3.12 or newer, which means QGIS 3.40 or newer.
