OK, so I am trying to make a GeoTiff image from your the Sentinel 3A Level 2 OLCI CHL_OC4ME band (file from CODA named S3A_OL_2RR*). I am interested in output the Chlorophyll product in a specific area of interest with a Mercator WGS-72 projection. I understand I first need to Georeference the band using the embedded geo_coordinates (lat and long bands) then maybe re-project or warp it then output that image as a GeoTIFF. I am having trouble finding the correct tools and workflow. Can you please help.
Thanks, Matthew Upton
