Given a list of georeferenced rasters, about a hundred, what is the simplest method to generate world files for each?
In this case the source rasters are either geotiff with embedded georeferencing or .BIL with accompanying .PRJ, but the ideal solution shouldn't care what the format is. I'm hoping to avoid duplicating data.
I have at my disposal Arcgis 10 (Arcinfo & Spatial Analyst), GDAL Utilities (gdal v1.8.0), and Quantum GIS 1.8.
Answer
If you're using a recent build of QGIS, you may already have access to the Extract Projection tool mentioned here.
From the article: "What this lets you do is to find out what projection your rasters are in. It then exports this to a .WLD file. It also allows you to create .PRJ files. If you have GDAL Tools installed (and activated), you'll find this new tool under Raster > Projections > Extract Projection."
It includes a batch processing option as well, which is great for your purposes.
