Welcome, Meltintalle! Sounds like your early field work was an excellent basis for a lifetime of map interest :-). Now I understand some copycat outfit named Gargle or Giggle or Google or the like is using bikes in its street mapping projects. Ha. Johnny-come-latelies.
So do you already have access to graphics tools with which to map? I mean other than pen and paper, which are fine; you'd just need a scanner before we could comment and critique your efforts.
