I downloaded Landsat images of Banjul from
ftp://ftp.glcf.umiacs.umd.edu/glcf/Landsat/WRS2/p205/r051/p205r051_7x20001106.ETM-EarthSat-Orthorectified/and
started playing around a bit. The result ended up looking like this:

Compare with how this looks in OpenStreetMap today and in OpenAerialMap
(iCube Landsat):
http://www.openstreetmap.org/?lat=13.394&lon=-16.358&zoom=11&layers=B000FTF
http://www.openaerialmap.org/?lat=13.42284&lon=-16.56708&zoom=11&layers=BF

I have not tested the same settings at other places, but it does at least
indicate that automated tracing from selected Landsat data could be
possible.
