Hi all I'll like to add overviews to a 1 bit geotiff the gdalinfo for this tiff is: *************************************** Driver: GTiff/GeoTIFF Files: test.tif test.tfw test.aux Size is 292042, 284413 Coordinate System is `' Origin = (2311161.564860595900000,5168752.558307543400000) Pixel Size = (0.426789595821517,-0.426789595819635) Image Structure Metadata: COMPRESSION=CCITTFAX4 INTERLEAVE=BAND Corner Coordinates: Upper Left ( 2311161.565, 5168752.558) Lower Left ( 2311161.565, 5047368.049) Upper Right ( 2435802.052, 5168752.558) Lower Right ( 2435802.052, 5047368.049) Center ( 2373481.808, 5108060.304) Band 1 Block=256x256 Type=Byte, ColorInterp=Palette Description = Layer_1 NoData Value=0 Metadata: LAYER_TYPE=athematic Image Structure Metadata: NBITS=1 Color Table (RGB with 2 entries) 0: 255,255,255,255 1: 0,0,0,255 *************************************** I used: gdaladdo -r average --config USE_RRD YES test.tif 2 4 8 16
The result is a file called test.axe 20Gb big and a test.aux file (5Kb) gdaladdo.exe don't seem to work, in taskmanager it uses 0 to 0.1 cpu% Gdal 1.9.2 installed with osgeo4w. By the way, which is the best way to create overviews for this kind of tiff??
