Hi, Standard recipe is to use tiled tiff file with overviews, perhaps both compressed. Uncompressed: gdal_translate -of GTiff -co tiled=yes -co bigtiff=yes image.png image.tif gdaladdo -r average image.tif 2 4 8 16 32 64 128 256
You may want to save space by making a compressed tiff. If it is aerial image, use jpeg compression, if a map, then LZW or deflate. For aerials it would look about like gdal_translate -of GTiff -co COMPRESS=JPEG -co PHOTOMETRIC=YCBCR -co TILED=YES image.png image.tif gdaladdo -r average --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW YCBCR 2 4 8 16 32 64 128 256 -Jukka Rahkonen- jcwalz wrote: > Hello, > > I have a png raster image that I am adding to GeoMOOSE and it is about 3GB in > size.
