[Benchmarking] raster processing

[Frank Warmerdam]

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:
