Is there a handy dandy utility that would do that for you? Or how can one do this manually?
If you’re not adverse to spending some money for a professional tool, there are dozens of programs for converting pictures into drawings for CAD programs and topographic maps into data for other uses as well. Based on a recent survey I did for my real job, these range in cost from around $80 USD to over $1500USD depending on the features and degree of processing required.
Nevertheless, I had need for one for purely technical purposes and chose the R2V Toolkit from AlgoLab
http://www.algolab.com/r2v.htm which sells for $99 USD and for my purposes (turning mostly scanned drawings of aircraft into vector data for use in a specialized program that I wrote for my employer) its quite capable. But I’ve never tried it on anything even close to a "photograph" so I can’t really comment on how well it woud do that.
