I added to "band_data" a '_CRS' attribute as dict with 'url', 'wkt' & 'projjson' infos (EPSG 3857), saved the whole thing as file and hoped can open it in

However seems to have trouble finding the coordinate reference and assumes the origin is 0,0 (Extent 0.0, -8192.0 : 4096.0, 0.0).

Now, my question: where do I store the "_CRS" dict correctly? Do I also need to add a GeoTransform infos? If yes, where?

Sorry, that I misuse this platform for my silly question:

I have a dataset
Dimensions: (time: 1, band: 4, y: 8192, x: 4096)
Coordinates:
* time datetime64[ns] 8B 2023-06-15
* band <U5 80B 'Red' 'Green' 'Blue' 'Alpha'
* y float32 33kB 7.064e+06 7.064e+06
* x float32 16kB 1.194e+06 1.194e+06
Data variables:
band_data (time, band, y, x) uint8 134MB dask.array<chunksize=(1, 4, 1024, 1024), meta=np.ndarray>
spatial_ref int64 8B ...

Have you ever thought to yourself: "It sure would be nice to see the geometry for baseball fields of Nebraska" or "raceways of Germany"... wow, me too! That's fun.

X-of-Y may be the perfect thing. You give it an overpass query and it does it's best to show you everything neatly side by side.
