Hi all, Opening ALOS AVNIR-2 & PRISM (CEOS format) images using GDAL is really slow and uses loads of memory on Windows XP. This includes things like gdalinfo and opening via the python bindings (gdal.Open()).
I've tried (on WinXP) with various gdal installs (fwtools, osgeo4w, basic binaries) and same issue. Is anybody else experiencing this, is this a bug that I should log? Below is an example using gdalinfo on an ALOS PRISM image on WinXP & linux. Testdata is from: http://www.ga.gov.au/remote-sensing/get-satellite-imagery-data/product-s amples.jsp Regards Luke Pinner Example: **Windows XP (32 bit)** C:\> gdalinfo --version GDAL 1.6.2, released 2009/07/31 C:\> gdalinfo U:\work\testdata\alos_prism\ceos_02041_02b\product\scene01\img-alpsmb021 733905-o1b2g_ub Driver: CEOS/CEOS Image Files: U:\work\testdata\alos_prism\ceos_02041_02b\product\scene01\img-alpsmb021 733905-o1b2g_ub U:\work\testdata\alos_prism\ceos_02041_02b\product\scene01\img-alpsmb021 733905-o1b2g_ub.aux.xml Size is 18855, 17086 Coordinate System is `' Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0,17086.0) Upper Right (18855.0, 0.0) Lower Right (18855.0,17086.0) Center ( 9427.5, 8543.0) Band 1 Block=18855x1 Type=Byte, ColorInterp=Undefined Min=1.000 Max=255.000 Minimum=1.000, Maximum=255.000, Mean=69.835, StdDev=18.376 NoData Value=0 Metadata: STATISTICS_MINIMUM=1 STATISTICS_MAXIMUM=255 STATISTICS_MEAN=69.834780742218 STATISTICS_STDDEV=18.375728841108 Takes: 111 seconds Peak mem usage: 636 Mb **Ubuntu 9.04 (64 bit)** $ gdalinfo --version GDAL 1.6.2, released 2009/07/31 $ gdalinfo /data/work/testdata/alos_prism/ceos_02041_02b/product/scene01/img-alpsmb 021733905-o1b2g_ub Driver: CEOS/CEOS Image Files: /data/work/testdata/alos_prism/ceos_02041_02b/product/scene01/img-alpsmb 021733905-o1b2g_ub /data/work/testdata/alos_prism/ceos_02041_02b/product/scene01/img-alpsmb 021733905-o1b2g_ub.aux.xml Size is 18855, 17086 Coordinate System is `' Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0,17086.0) Upper Right (18855.0, 0.0) Lower Right (18855.0,17086.0) Center ( 9427.5, 8543.0) Band 1 Block=18855x1 Type=Byte, ColorInterp=Undefined Min=1.000 Max=255.000 Minimum=1.000, Maximum=255.000, Mean=69.835, StdDev=18.376 NoData Value=0 Metadata: STATISTICS_MINIMUM=1 STATISTICS_MAXIMUM=255 STATISTICS_MEAN=69.834780742218 STATISTICS_STDDEV=18.375728841108 Takes: 1.4 seconds Peak mem usage: 0.6 Mb (ps -o rss) ------ If you have received this transmission in error please notify us immediately by return e-mail and delete all copies.
