GDAL strikes back...

I find myself working with GDAL tools with various projects from time to time and always I appreciate the people behind it.

Now some memo for myself:

Adding tiles to a geotiff with specific block size:
gdal_translate -co TILED=YES -co BLOCKXSIZE=512 -co BLOCKYSIZE=256 mytif.tif output.tif


Compressing a geotiff (use it if the raster source is imagery, not very suitable for elevation and other data)
gdal_translate -co COMPRESS=JPEG -co TILED=YES -co JPEG_QUALITY=85 mytif.tif output2.tif


Adding overlays from to a geotiff file (taken from here):
gdaladdo -r gauss --config PHOTOMETRIC_OVERVIEW YCBCR --config COMPRESS_OVERVIEW JPEG --config JPEG_QUALITY_OVERVIEW 85 output2.tif 2 4 8 16 32 64

Nice tool for command line operations - sfk

This utility has some nice shorthand features that helps a lot when dealing with lots of files if you have limited knowledge of scripting ...

Link Shell Extension

Hardlinks provide the ability to keep a single copy of a file yet have it appear in multiple folders (directories).

Now for NTFS it is possible to define new hard links, junctions etc. It is very useful if you use DropBox and sync different folders.

It is freeware, you can get it from the link below;
