, Permafrost extent for the Northern Hemisphere, v3.0
Adding data to the map as usual: the layer has incorrect georeference.
Let's try to study the dataset with Xarray
crs_wkt
is in GDAL-compatible format, we can use it. But GeoTransform
is not consistent with dataset upper left pixel coordinates:
The full notebook download is below. To run it, , savethe notebook to your working directory, and run Jupyter Notebook from this directory.
To export data as GeoTIFF some info georeferencing is needed. For GDAL it is a projection (crs reference) and parameters (upper left x and y coordinates and pixel size). Some of this info is stored in the polar_stereographic
variable.
