salem.DatasetAccessor.lookup_transform
- DatasetAccessor.lookup_transform(other, grid=None, method=<function mean>, lut=None, return_lut=False)
Reprojects an other Dataset or DataArray onto self using the forward tranform lookup.
See :
Grid.lookup_transform()
- Parameters:
- other: Dataset, DataArray or ndarray
the data to project onto self
- grid: salem.Grid
in case the input dataset does not carry georef info
- methodfunction, default: np.mean
the aggregation method. Possibilities: np.std, np.median, np.sum, and more. Use
len
to count the number of grid points!- lutndarray, optional
computing the lookup table can be expensive. If you have several operations to do with the same grid, set
lut
to an existing table obtained from a previous call toGrid.grid_lookup()
- return_lutbool, optional
set to True if you want to return the lookup table for later use. in this case, returns a tuple
- Returns:
- a dataset or a dataarray
- If
return_lut==True
, also return the lookup table
