Der fellow R-users,
I have several sampling sites and in each site the starting plot
(i.e. the first one that have been sampled) is georeferenced with a
GPS but the following ones are just described by their distance and
bearing in relation to the previous one.
Is there a quick way to calculate
I cannot remember the names, but there would be support for this in the
maptools or geosphere package I am sure
