Dear Wilson Ruy Mozzato Krukoski,
In Australia, geodesics are by far the most common line type used in
Treaties and domestic legislation. I believe the main justification for
this is that the geodesic is effectively the shortest line between two
points on an ellipsiod and therefore the 'fairest' line for delimitation.
The only real problem with geodesics is that they plot as a curved lines on
mercator projections and therefore to accurately represent them on charts
you may need to insert intermediate points on long lines. This is not bad
practice anyhow as the use of intermediate points on long lines ensures that
they plot in roughly the right place regardless of projection.
