RS_GeoReference

Returns the georeference metadata of raster as a string in GDAL or ESRI format. Default is GDAL if not specified. For more information about ScaleX, ScaleY, SkewX, SkewY, please refer to the Affine Transformations section.

If you are using show() to display the output, it will show special characters as escape sequences. To get the expected behavior use the following code:Scala

println(df.selectExpr("RS_GeoReference(rast)").sample(0.5).collect().mkString("\n"))

Java

System.out.println(String.join("\n", df.selectExpr("RS_GeoReference(rast)").sample(0.5).collect()))

Python

print("\n".join(df.selectExpr("RS_GeoReference(rast)").sample(0.5).collect()))

The sample() function is only there to reduce the data sent to collect(), you may also use filter() if that’s appropriate.
