This would translate much more naturally to a GeoPandas' GeoDataFrame of Xarray DataArray objects than a plain data cube (seeherefor how this could work). It *is a * vector layer when you treat it as one (it's an abstraction), when you treat it as a "GTI:" it is a raster (a...
In this example, we first check if the CSV file exists using theos.path.isfile()function. If it does, we read the data using Pandas’read_csv()function and continue processing the data. If the file does not exist, we print a message and avoid a potentialFileNotFoundError. ...
