I am trying to automatically digitize forestcover polygons from dashed lines using ArcScan and it is not quite working out. I have used the gap closure tolerance setting and that seems to work very well for creating lines, however, when I go to directly create polygons it doesnt detect that gaps and just creates polygons around each individual dashed line.
Byron, Have you tried creating polygons from your line file? I've done that in the past, create two shapefiles for each raster (line file and poly file), and then convert lines to polygons. Lena
