Image Tiling

[Ethan Alpert]

I use imagemagick and gdal_translate to split and build tiles from large
images. Then I build a tile index with gdaltindex. As long as you tile
index layers MIN/MAX scales are set right you get a pretty big
performance gain. However if you're rendering many of the tiles in the
same image it slows down. I create overviews for large scales and
display those and have the tile index only come on at lower scales.

What kind of programs/scripts do most of you use to tile .tif images?
I'd be interested in playing with this. Do any of you that use tiled
images notice an improvement in performance?
