I have a very large imagery set (~1 million files). When running VirtualPlanetBuilder 0.9.9, I am limited to about 482 -t imagery files for a given vpbmaster command before I get "ERROR 4: Failed to open file /mp2/osg/file482.tif" for each -t file listed after the 482nd file listed in the script and the *.ive files are not created.
The command I am using is: vpbmaster --PagedLOD --geocentric --terrain -e 30.00 20.00 1.00 1.00 -o 30_20.ive Running with the -t option pointing to the directory results in the same error. What do I need to open up to allow more files to be processed per vpbmaster run? Secondly, a test of a small VPB database of 1.34GB of CADRG imagery produced 14.941GB of *.ive files using VPB 0.9.7 in 23 minutes time. The same test with VPB Version 0.9.9 produced 14.826GB of *.ive files in 32 minutes. I was not expecting the newer VPB to only produce a tiny (<1%) amount of compression, while taking about 40% more time. Furthermore, I'm perplexed that my resulting output files are 11 times the input imagery (1m black and white Controlled Imagery Base). Using the --compressed option made no difference to the resulting *.ive sizes. I require all levels of detail, so expect some increase in database size, but can anybody help me reduce this to a smaller multiple as I'm running out of disk space! What do I need to do to turn on Heightfield compression, for example.
