There's a RasterToPolygonCoercer transformer in FME2012, but I really
don't hold out much hope. Those images are going to be really tough to
turn into vector features.
The only thought I have is to turn it into an 8-bit greyscale (I'm
assuming black+white = 1bit image?) and resample it to a coarser
resolution. That might help pick out the shading of the buildings, but
I'm not certain.
This page on fmepedia also shows vectorization with FME, but again I'm
not sure if it will work with your images:
Sorry to be negative. I just don't want you to waste too much time in
a losing battle. I fear that FME is not going to be the best tool for
this job. But if you find a way then please let us know - I'd be
interested to see your method.
