raster_df.createOrReplaceTempView("raster_table")
in SQL,
SELECT RS_AsBase64(raster) from raster_table

Hi @chitra-psg, Thank you for pointing out the issue. Originally we didn't intend to include any floating datatypes to the `RS_AsBase64` function. However, I will add support to floating point datatypes.
I would not recommend that you use `RS_AsBase64` on such a large file. This function should be used only with relatively small files. If you want to visualize it, you may use `RS_AsGeoTiff` and https://sedona.apache.org/1.5.0/tutorial/raster/?h=save+files#save-to-permanent-storage.
