Density of fishing vessel transits, expressed in kilometres per squared kilometres, within the spatial reference EPSG:3035 and including the INSPIRE compliant cell identifier. Transit distance was calculated from the CIMA Foundations AIS dynamic point data which was recorded from an antennae located at 44.30°N and 8.45°E between May 2013 and October 2014. After an initial preparation, cleaning and filtering procedure, a GIS platform was used to create line transits from the positional points for each unique vessel for each day. The length of the transits were then summed within each grid cell for total and monthly composites covering the North West Mediterranean Sea.
