Try MapScan from the UN:
Here's the link. I just visited the site today, there are some broken
links about its details, but it may be worth your while to try out. Hey,
it's free at least. I don't know exactly how robust it is, but if it works
for you it's worth the effort.

MapScan is a software that accepts various formats of scanned maps or
drawings, reads and converts them into vector
maps in formats that can be used by popular mapping systems. MapScan will
enable you to move printed maps or
drawings into a mapping system quickly and easily, compared to traditional
digitizing techniques.
Key Benefits
The system offers an easy-to-use graphical user interface, and is designed
for analysts, researchers, demographers,
geographers cartographers, and almost any one who needs to computerize
paper maps with little or no prior computer
background or experience in graphics drawing and map manipulation.
MapScan combines several components into one package:
a set of tools for editing and cleaning raster and vector maps.
an OCR engine for extracting text labels from the raster maps, and
for preserving their relative coordinates.
a state-of-the-art line vectorization engine enabling interactive
line tracing, and automatic map vectorization with
built-in topological reconstruction.

Subject: MI-L Creating polygons from scanned images
Question... I have a client who e-mails me bmp files created in Paint in
which he has drawn lines to delineate soil mapping units. I then import
the bmp's to MI and create polygons over his lines to get acreages and also
to be able to color the polygons according to series. This is somewhat
tedious, but does produce a nice map. Is there an easier way??
Thanks in advance.......tom
