Welcome to the iMARE Culture Seafaring webservice!
Here are some tips on how to use it so that you may have a smooth experience:
Port of Departure/Arrival: Please select the ports of your choice. Mind that the ports names in the list are those used in ancient times, therefore prior selecting, we advise you to hover with your mouse on the orange circles at the map so to have displayed the ancient name.
Output: Please select one of the methods listed here to get the corresponding result of the sailing process.
Path: Displays the path between 2 ports.
Path (w/cabotage): Like the path above but it considers the weather conditions and if needed it makes stops at nearby ports. If selected, user needs also to select the port behavior ("Start after Days" or "Start after Hours"), max days at sea (integer number), days to stay at port (integer value only when port behavior is set to "Start after Days", otherwise please leave it blank), hours to stay at port (integer value only when port behavior is set to "Start after Hours", otherwise please leave it blank).
Isochrone Contour: This method returns the isochrone of the ship’s sailing method. By default, the time is set to 24 hours but please feel free to enter an integer value for the contour so you may check the length of the path the ship travels within the specific timespan.
Isochrone Contour (w/cabotage): Works like the method above but it considers the potential stops during ship’s travel. The fields displayed here are the same with the “Path (w/cabotage)” method.
Sailing/Polar Diagram: Please select one of the sailing methods that our algorithm calculates to display the corresponding result.
Run Monthly Path: By checking this method you can get back the routes of the ship’s travel on monthly basis between the 2 selected ports, as well as after the process has finished you may download in .txt format the results of the paths.
Add second path: This option becomes available only after the first execution of one of the methods above (output), if checked you can display a second path/travel on the map.
Departure Date: Please select your desired date of travel.
Departure Time: Please select your desired time (in hours) of travel.
Wind Grid: User is able to check the visualization of the wind conditions for the selected date and hour of travel.
Calculate button: Visualizes the path(s) of your selected choices.
