[Gdal-dev] Merging TIFFs

[Andrew Larcombe]

Hi all,

I'm after a quick bit of advice before I start coding. I need to write a 
small app that will take a 4000x4000 pixel striped geotiff at resolution 
x and merge it into a number of larger ~10000x10000 pixel tiled (200px 
tile height & width) geotiffs at resolutions y1...yn where y1...yn < x. 
Both input and output are in the same projection.

Am I best off using the GDALWarp classes or the 
GDALRasterBand->RasteIO() stuff?

TIA,

Andrew
