Ciao Stephen, I downloaded the data and ran a quick test. The pyramid creation was smooth, although I noticed that the geotiff files you have provided us with do not contain a proper EPSG code for the CRS. I picked one that was close enough and forced a reprojection (not the best thing performance wise). Things worked for me in the end (although as I said I have a few local changes that might have helped)
My questions for you are as follows: - do you know a valid EPSG code for this dataset? - why you using tiff that big for the single granule/tiles? Ciao, Simone. ------------------------------------------------------- Ing. Simone Giannecchini GeoSolutions S.A.S.
