Introduction: Returns the georeference metadata of raster as a string in GDAL
or ESRI format. Default is GDAL if not specified.

Review Comment:
This is not a SQL example. This should be a language-specific example. You
need to provide examples for (Scala/Java) and (Python). Please also say
`sample()` here is to reduce data to be collected. Other functions such as
filter() will work as well.
