Hi Viking team, Just wanted to tell you that Viking has been a great help for me. I used it for planning a bicycle trip in tuscany. Unfortunately, coverage by openstreetmaps is still lacking there.
My only hope to plan the tracks was to scan the (1:100000) map provided with the pre-information by the organizer. I did not know of any way to convert locations in the scanned image to lat/lon though, so I decided to try to extend Viking to do just this. I ended up spending about 4 hours to add the feature I needed (albeit in rudimentary form). It adds a new "image" layer type. The properties of that layer consist of the image path, a x/y pixel location in the upper left and the lat/lon of that pixel and the same for some pixel in the lower right of the image. With that information, the image is scaled to match the two points on display. Of course this is a coarse approximation, but it turned out to be good enough. The accurary of the track points I created in this way was about 200 m. Perhaps it could be worthwhile to improve on my code and include this feature into Viking proper. I put up a screenshot and links to the git repository on http://landschoff.net/trac/stuff/wiki/Patching%20Viking%20to%20plan%20our%20bicycle%20vacation Friendly, Torsten ------------------------------------------------------------------------------ Come build with us!
