I try to avoid serious problems with this by cheating. I create a
reference image with a "nice" set of dimensions for importing into a
program or script that can give me row-major or other ASCII ordering of
numerical values that I can import with an appropriate header. When this
is not possible I import it into IDRISI for Windows V 2 and georeference
it (really simple in lat/lon under IDRISI if I am careful) and then
export an ascii fle I can muck with. For contours I would probably
digitize or "scan and scale" if it was hand-drawn or derived from
another source.
For what its worth....
