[Qgis-user] How to project data?

[John Callahan]

Carson,

This is great.  This is exactly what I was looking for.  I'm also 
looking at your other plugins and will probably try out several of these 
as well.  Thanks!

For rasters, using GDAL works great; even projecting in batch mode can 
be done with simple scripting.  However, including raster srs management 
within QGIS will be very helpful for the majority of users.
