I have scanned images of B&W maps of towns in PerĂº. I want to turn these into GIS layers.
 
Applications that will do this (free or cheap)? and make a file Maptitude will read.
 
Words of caution and/encouragement?
 
These maps are scanned at 400 dpi but many of the lines are spotty, unintentional breaks, likely not all that good maps to begin with (I do not have access)
 
Several have map grids overlaying the map. I have control points, again, the line quality is sometimes broken. Also some noise, that is little smudges, also text.
 
thanks -
