Would someone care to recommend a free and/or open source GIS application that can orthorectify map images?

For orthorectification:

In GRASS see i.ortho.photo.
In OSSIM, see OSSIMOrthos.pdf

For georeferencing:

In Quantum GIS, use the Georeferencing plugin, p 172 of the users guide.
There is even an online tool for georeferencing at http://www.georeferencer.org/

And just remember that you will need an elevation datasets such as a DEM to rectify the imagery to. – jvangeld May 5 '11 at 20:16

INPE in Brazil (National Institute of Spatial Research) has an software called Marlin used for some raster data processing. It's known Marlin can orthorectify, tough I don't know how to proceed. But it's free.INPE also develops the SPRING software. It a GIS suite that can orthorectify and it's free as well.

But unfortunately, those two softwares are not open-source.

Qgis or Grass or uDIG ... For each of these software look into the plugins and 3rd party plugins as well

Note that only GRASS GIS supports it, in this suggestion it is used as extension in QGIS or uDIG. – markusN May 6 '11 at 13:51
