> Q1: What effect does different tile size have on storage and performance?
Biggest tiles = longer to load in memory and less efficient indexing I suggest you experiment with much smaller tiles: 100x100 and 10x10 > Q2: We will need to be getting raster values from a large number of > point tables over a large number of raster tables. Is there any method > to speed up the queries? If your rasters are all of the same size and cover the same footprint I would suggest to make them different bands of the same raster. So for the same point you will search for the right tile only once.
