That was one of my questions, how to make analasys on tiled rasters? Is that possible or not, I tried to make ST_Union on 200 tiles and I stopped it after a few minutes :)
I am testing raster automatic publication of OGC services through PostGIS raster and image mosaic JDBC plugin and Java a I am quiet satisfied, but I have only small rasters (max 30 Mb), I expected that it will be really slow (reading raster from database, merging together and visualize them), but I am quite surprised. But I expect that the same rasters will be faster from file system.
