Tiled TIFFs

See also GeoServer.

Convert TIFF (tif+tfw) to GeoTIFF with GDAL:

 gdal_translate -of GTiff -co "TILED=YES" input.tif tiledGeotif.tif

By using the TILED=YES parameter we ask the command to prepare the file for tiles rendering. Now the size of the resulting file is larger.

Then create overviews for the GeoTIFF file:

 gdaladdo -r average tiledGeotif.tif 2 4 8 16
