  2. Hi Andi,
    I am a new visitor to your blog. Was searching about digitization and this space seems to impart digitization processing in a simple way. I would like to share the information of this tutorial with some of my friends.Conversion from raster to vector is explained as simple as possible. It would have been better if you could also have specified the name of the software used for GIS vector conversion.
    Regards,
