[postgis-users] Raster images

[Stephen Woodbridge]

Hi Warren,

There has been a lot of discussion about rasters on the list and the 
dev-list so you might want to read some of that. But I will summarize in 
really short form and leave it to others that chime in if I have it 
wrong ot there are other options.

Today, I think your best bet it to keep the raster data as files but to 
use postgres/postgis to the manage you raster colection. So you might 
include metadata, transform info, size, path to the file on disk, you 
might also want to create polygon or bbox representations of each raster 
file so you can use spatial search against these and other data you have 
in postgis.

If you are working with mapserver, I would read the mapserver archive 
for posts by Ed McNierney on rasters. He runs Topozone.com and they have 
nearly a million rasters online that require ablut 20TB of disk space.

Hope that helps,
   -Steve W
