Digitizing Satellite Imagery

Question asked by isservice on Apr 3, 2017



I am trying to find the easiest and most accurate way that i can create vector data from a 50cm satellite image of my ENTIRE country.  I know i can manually digitize it, I have also come across image classification. Manual digitization may prove more accurate , however it is very tedious. 


Can anyone recommend an alternative solution to vectorizing roads and buildings and other features from a satellite image? Could anyone advise on the best methodology?
