Folks,
I have completed reprocessing the raster files into regular TIFF quarter
images rather than full images in bigtiff format. The file are in
/benchmarking/data/raster on the linux server. Mike, perhaps you could
move them over to windows?
Processing was done with commands like:
gdal_translate PNOA_MA_OF_ETRS89_HU31_h50_0448.ecw
PNOA_MA_OF_ETRS89_HU31_h50_0448_tl.tif -a_srs EPSG:25831 -co TILED=YES -srcwin
0 0 25000 20000
gdaladdo PNOA_MA_OF_ETRS89_HU31_h50_0448_tl.tif -r gauss 2 4 8 16 32 64 128 256
An example report on a file is:
Driver: GTiff/GeoTIFF
Files: PNOA_MA_OF_ETRS89_HU31_h50_0448_tl.tif
Size is 25000, 20000
