           | 
           | My problem with is, a margin of error of 25 meters for a run
           | of less than a km isnt what I would call platinum, my gripe
           | here is with geowizard. I feel the error margin should
           | increase for each km, for example by one meter. So a straight
           | line across a continent allows for a larger margin of error,
           | but 1km , well you better stick to the line.

             | The OP used GeoWizard's measurements for the points (like
             | less than 25m for Platinum) but GeoWizard usually goes for
             | waaaaay longer than 1km. So the "fault" is on OP, if at
             | all.

         | rigorous definition.
         | 
         | I was thinking of saying Norway and New Zealand look OK because
         | in both cases you start on the eastern border/coast and finish
         | on the western one, unlike Queensland where you are still in
         | the northeast by any definition. This gets close to my intent,
         | but to make this work we have to accept that NZ has multiple
         | east coasts, or a single discontinuous one. Why is it OK to
         | cross the North Island in NZ, but not OK to cross some tiny
         | island in Australia (e.g. cross King Island [1] from west to
         | east)?

       | For pure straightness, somewhere like Canada, Greenland or the
       | UAE would probably allow you to walk a more-perfect strait line
       | from one coast to another through open territory. Such a trek
       | would be far more difficult but much more strait.

           | Regarding Norway, it being private land wouldn't matter much.
           | It is written in Norwegian law [0] granting the right to
           | travel the land without too many restriction. Private
           | property is not one such restriction. One should avoid
           | farming fields during spring, but in broad strokes that's
           | pretty much it.
           | 
           | This includes the right to forage (berries, mushroom,
           | whatnot). Though hunting and fishing can be quite restricted.
           | Motorized vehicles have their own set of restrictions, but
           | trekking, biking, sailing, etc are fine.
           | 
           | So, one cannot for instance fence off the access to nature,
           | like a "private" beach etc. And camping is allowed everywhere
           | not within 150m of a house/cabin with residents up to two
           | days, though relocating to somewhere else would be fine.
           | Farmland is again an exception, and you should ask the owner
           | for permission.
           | 
           | PS: There are local exceptions everywhere, so be sure to
           | check that. Some waters are protected, etc. Some regions are
           | considered "protected nature", which doesn't trump
           | "allemannsretten" (the aforementioned rights), but there can
           | be other restrictions. And in all cases, it is expected to
           | not leave behind garbage or cause damage.
