Thank you @jiayuasu ! 1. Yes! Now we should be able to implement all the raster functions in Postgis. 2. I think we can adapt the GeoTiff writer to work with rasters as well as the current double arrays. We just need to figure out exactly how that would work from a user perspective. I'll start a discussion on the mailing list about that. 3. I think that the raster functions in this PR and the current ones, that operate on bands, are complementary. We just need to implement a few function bridging the two. If we can extract bands from rasters and also create rasters from bands the old and new functions will work well together. There are many examples in Postgis we could use as inspiration: https://postgis.net/docs/RT_ST_AsRaster.html https://postgis.net/docs/RT_ST_AddBand.html https://postgis.net/docs/RT_ST_DumpValues.html https://postgis.net/docs/RT_ST_DumpValues.html -- This is an automated message from the Apache Git Service.
