FME currently does not provide a native way to control compression of raster overviews (pyramids) when generating outputs such as GeoTIFF or COG, limiting the ability to optimize file size and performance.
In real-world workflows, especially when handling large raster datasets, overview compression is essential to ensure efficient data access and reduced storage requirements.
At present, achieving this requires the use of external tools, which breaks the native FME workflow and adds unnecessary complexity.
Request:
Add native support for overview compression (method, quality, predictor, etc.) in raster writers or transformers.
This would enable fully native workflows within FME and significantly improve efficiency in production environments.
