Hello!

I need an advice.

I'm trying to transform a topographical map (black and white) into a vector representation.

I've tried with ArcScan from ESRI, it has some useful profiles but the final result doesn't fit my needs.

After that I have to filter the result and it take time. The needed time is comparable to the classical method of digitization on the screen.


Please suggest another idea/software.

A good day

Sincerely,
Adrian

Wintopo might be worth a look:

Depending on your end product needs (e.g., an image vs. a geospatial vector data set) you should check out http://vectormagic.com a slick online and desktop product for vectorizing raster images, though it deos not maintain any geospatial intelligence.

A good point. Sorry, I should have mentioned about the free version of Wintopo, do a world file calibration of the image first. This will ensure that the geospatial data gets written to the vectors.
