easy mapping - So the trick to map easily is:
I take pictures with my Canon Powershot A630, and get the gps information from my telephone.
I match them with gpscorrelate-gui (I have to get the proper commandline yet…). The most important part is calculating the difference between your camera and your gps, so you can align them perfectly. For doing so, a nice trick is to start the mapping taking a picture of the gps driver.
