Figure 8. VMSbase interfaces for a) “Mark fishing points” tool, which allows the user to specify the speed and eventually the bathymetric range for different fishing activities; b) “Effort Gridding”, the tool designed to associate fishing effort with grids or other partitioning, which are then plotted and exported in the desired formats.

This tool returns a value (hours of fishing effort activity) for each cell of the grid, while the results can be saved and exported as ESRI shapefile or CSV textfile; c) “DCF Indicators”, the tool aimed to compute the values for DCF indicators of fishing pressure 5 and 6.
