Great article and site!

VT Builder has a projection converter (that uses GDAL I think) and has an easy interface. Once the images or elevations are reprojected, they can be cropped if required and exported to various formats.

You called it – ERDAS Viewfinder is the program I was referring to at the end. I’m putting up that post right now on the blog.

ERDAS ViewFinder 2.1 (free) can handle some raster reprojections. I recall it being a bit picky about handling projection, world files, geoTIFF header for it to work properly.

I think Global Mapper is great – I have an older version of it, and use it all the time. But $270 per copy is not inexpensive, especially if you don’t need all its features.

“But they’re expensive”. I would not call it expensive (270USD (with a 10% discount registering at http://www.globalmapperforum.com), or atleast the least expensive alternative. It`s also a good thing that you can try every function before you buy it, just contact the developer.

It might seem difficult at first, but learning GDAL/OGR is worth every minute you invest in it. There really is no comparison for projection / warping operations. The best part is that once you learn the syntax, the other great GDAL tools become available to you for converting, rescaling, and editing GIS data.
