Best method for transforming raster to vector
Posted 28 September 2009 - 04:39 AM
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

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.
