This data set provides the pseudo-positions in space and time of two fishing vessels and the associated activities (fishing, cruising, stopped, recorded by an on board observer). It supports the analyses provided in a paper published in Methods in Ecology and Evolution and the methods of the R package m2b (https://cran.r-project.org/package=m2b).For privacy concerns, original latitude, longitude, time and vessels id were modified. Spatial data were scaled and centred to a fictional position (Rlyeh position, Lovecraft 1928) keeping the relative geometry unchanged (acceleration, time between two positions....). Time and vessel id were modified in the same manner, keeping the relative properties of the tracks unchanged (time succession, differentvessel id...). Vessel id and time are purely fictional and follow the historical context proposed by Lovecraft (1928) in the Rlyeh surroundings. Again, if the absolute spatial and temporal description of the fishing track were changed, their relative mathematical properties are conserved and can support behaviour detection based on relative movement analysis. For the data_vessel.csv file (csv file with header), the variables are x : pseudo longitude y : pseudo latitude t : pseudo time in year-month-day hour:minutes:second format b: fishing activity, namely fishing, cruising, stopped id: unique id by vessels (fictional names).
