iapesca, a R-package for manipulating and interpretating high resolution geospatial data from fishing vessels
|Other titles||iapesca, un package R pour la manipulation et l'interprétation de données de géolocalisation des navires de pêche à haute résolution|

These developments have been carried out through the IAPESCA and DELMOGES programs and inspired and guided by the methods and experiences shared during the ICES WKSSFEO in Lisbon in December 2021.
The purpose of this R-package is to provide generic methods for qualifying geolocation data regardless of the source using high-resolution geolocation data for fishing vessels, the methods provided aim at improving the calculation of vessel fishing effort and proposing metrics more suited for passive gears. The applications have been developed for fishing vessels operating nets with following metrics : fishing time, nets length and soaking time. They could easily be used or extended for active gears or other passive gears.
Different methods and tools are proposed for :
