Description

Currently, the GeoTiff loader in Sedona automatically transforms the coordinates to WGS84 when loading GeoTiff: https://sedona.apache.org/api/sql/Raster-loader/#geotiff-dataframe-loader

 

This may be a problem when CRS transformation fails. The user has no option to fix the transformation on their own. In addition, in many cases, WGS84 is not the best CRS.

 

We should provide an option to users and allow them to choose to do CRS transformation later on, by themselves. For example

.option("transformCRS", true)
