24h ??? for 40 GB ??!... how are you doing this ? you have access to a BlueGene computer or something like that ??!! :-)... From my side I need days or even weeks to build the blue marble data (with imagery and elevation only !!!)... (for example on a "standard" laptop with 2Gb of ram, Geforce 7950 GTX, dual core...) Am i missing something ???

Hi , I would just like to launch a little OSGDEM contest ... What is the biggest dataset you have processed with OSGDEM ? Up to now, I have processed the BlueMarble dataset : * 86400x43200 color + 21600x10800 geometry + 86400x43200 normal map + 32768x16184 clouds Which took approx 24 hours to process and produced 40 GB final data I guess of course , that I don't have the biggest dataset around ...but my obvious and evilly intent is to evaluate the potentials risks of processing a very big dataset , because I would like to process an approx 2.6Gpix * 1.3 Gpix dataset. I would then get a 4 TB dataset ... and 13 levels . Do you guys think this is feasible ? Shall the process time increase exponentially ? Do you have experience with such data ?
