22. def rasterJoin(right: DataFrame, joinExpr: Column, leftExtent: Column, leftCRS: Column, rightExtent: Column, rightCRS: Column, resampleMethod: ResampleMethod): DataFrame

    

    Performs a jeft join on the dataframe right to this one, reprojecting and merging tiles as necessary.

    Performs a jeft join on the dataframe right to this one, reprojecting and merging tiles as necessary. The operation is logically a "left outer" join, with the left side also determining the target CRS and extents. Right side may have multiple Tile columns. This variant allows for the specific geospatial columns and join expression to be specified.

    Performs a jeft join on the dataframe right to this one, reprojecting and merging tiles as necessary. The operation is logically a "left outer" join, with the left side also determining the target CRS and extents. Right side may have multiple Tile columns. Assumes both dataframes use the column names extent and crs for the Extent and CRS details for each row. The join expression used is:
