[raster] ST_AsGDALRaster ability to take set of rasters
|Reported by:||robe||Owned by:||dustymugs|
It just occurred to me that some raster types support multiple datasets e.g. animated gifs which would be nice for making time series movies of like climate changes where each raster in the dataset represents a different slice of time :)
MBTiles :) -- though I know those are readable in GDAL 2.0, not sure if they are generateable with GDAL 2.0 so that might be a theoretical.
things with pyramids where we have a high res, low res etc embedded in the file. Can't for the life of me think of one except MrSID and TIFF. I know there are others.
Right now our ST_AsGDALRaster takes as input only one raster which means as far as I can surmise, that it can only produce output rasters with only one data slice (set whatever you call it in GDAL speak). I guess we can in theory do it with gdal_translate tools etc, but would be nice to be able to do that right in the database.
