Hi everyone!
I'm trying to use elevation data in GeoTiff format. I understand how to
load the dataset, as described in
https://sedona.staged.apache.org/api/sql/Raster-loader/#geotiff-dataframe-loader.
Now I'm wondering how to join this dataframe with another one that contains
coordinates, in order to get the elevation data for those coordinates.
Something along these lines:
pointsDF
.join(geotiffDF, ...)
.select("lon", "lat", "geotiff_data")
Are there any examples or documentation I can follow to accomplish this?
Thanks,
