I guess it is a python question, then yes, it is two args function, see https://github.com/locationtech/rasterframes/blob/0.11.1/python/pyrasterframes/rasterfunctions.py#L1009-L1014:
def rf_resample(tile_col: Column_type, scale_factor: Union[int, float, Column_type]) -> Column:
"""Resample tile to different size based on scalar factor or tile whose dimension to match
Scalar less than one will downsample tile; greater than one will upsample. Uses nearest-neighbor."""
if isinstance(scale_factor, (int, float)):
scale_factor = lit(scale_factor)
return _apply_column_function("rf_resample", tile_col, scale_factor)
Definitely feels like it's never been exposed. You can try using Spark CQL though.
So to upsampling or dowsampling is not possible using "average" in pyspark? .. I was trying to convert a 10mt band of sentinel 2 to 20mt using this??
I have rasterframes version 0.11.1. When I try to use the rf_resample function: df.select(rf_resample("proj_raster.tile", 0.25, "max")), I get the following error: rf_resample() takes 2 positional arguments but 3 were given This function is supposed to take three inputs right? Or am I missing something?
