I see there are a few test cases to generate a tiled and even a BigTiff GeoTIFF in the GeoTools repository. E.g.
But, is there any case where we can generate a Cloud Optimize GeoTIFF?

A COG is just a GeoTiff with LZW compressed tiles, with internal overviews, so the standard writer ought to do with the Parameters set as described in the javadocs.
I can't work out how you would include the overviews explicitly or if they are automatically added for you.
- That is not the whole truth. In COG the headers are ordered in a specific way so that information that is needed first is written into the beginning of the file. It may mean total rewrite of a "normal" tiled and compressed TIFF (LZW is not the only compression option). Especially adding overviews to existing GeoTIFF breaks the optimization.

- that's very true.... so Ian, are in Geotools plans to support writing COGs out of the box?Χρήστος Χαρματζής– Χρήστος Χαρματζής2024-09-09 13:17:58 +00:00Commented Sep 9, 2024 at 13:17
