There's a company called queryobject (.com) which produces a compression engine for multidimensional datasets. I have no idea if it's suitable for your data, but it's interesting.
It sounds like a multidimensional database might be what you need. This type of DB puts the data into an array layout instead of a keyed lookup structure like most RDBMS's. Since your array is dense and rectangular it should work well and eliminate a lot of overhead.
GIS systems are more optimized for sparse, randomly distributed data in 2 or 3 dimensions. Received on Tue May 21 2002 - 20:34:30 CEST
