Depends on too many variables to say that software will always win, the key factors being what the actual application is, what kinds and how much data. There are very good reasons that google (and bing etc) serves up tiles into earth and maps and doesn’t operate from the compressed data.

That’s true Jeffrey, but his solution still is a magnitude sized better than using a full cache

And yes, the truth is $ either way (no such thing as a free lunch!). Although i can almost guarantee you the cost of an Apollo license would be offset extremely quickly by the cost of purchasing or paying for the equivalent storage with the alternative solution. So really, the scatterplot should be three dimensional, tile throughput vs storage cost (size) vs hardware/software cost.

I’ll put my money on software winning out by a significant margin. Any takers?

crschmidt’s answer still involves storing the imagery as uncompressed tiffs which would still inflate the on-disk size to something quite large with ~5TB of original compressed imagery.

The ‘truth’ is that its going to cost you $ either way, whether its for hardware (read disk) or licenses, and there are valid reasons for doing it either way.

Nice sales pitch!

Cris, the paper uses the GIO not IWS component. If they were to convert the 180gb IMG to JP2 or ECW, they would get further improved performance. You might like to contact T-mapy directly though to discuss

In the configurations used for Apollo (EAIM, EAS, EAP) is included the use of IWS component or not?

Download a Bluemarble scene as described in the post Brett, then configure FME server appropriately and run the benchmark with the tools i provided

Bart, afaik the ms4w/osgeo4w builds are missing jp2/ecw plugin support. If they remain excluded from the binary builds i will rerun the tests on the other formats ..
