Wind fetch is the unobstructed length of water over which wind can
blow from a certain direction. The wind fetch is typically calculated for many directions
around the compass rose for a given location, which can then be incorporated
into a larger model (such as the InVEST coastal vulnerability model;
<http://data.naturalcapitalproject.org/invest-releases/documentation/2_2_0/coastal_vulnerability.html>),
or simply averaged for a reasonable measure of
the overall wind exposure for a specific marine location. The process of calculating
wind fetch can be extremely time-consuming and tedious, particularly if a large
number of fetch vectors are required at many locations. The 'fetchR' package
calculates wind fetch and summarises the information efficiently. There are
also plot methods to help visualise the wind exposure at the various
locations, and methods to output the fetch vectors to a KML file for further
investigation.
