The above map shows berth occupation using an algorithm to decide where the vessels are moored. This is done using the speed of the vessels. When the speed drops beneath a threshold then the vessel is considered as moored.
The berth occupation is calculated for a berth using the dimensions of the vessels and the dimensions of the berth. There are two methods available based upon the provided berth dimensions (only length or surface calculation). In case of missing dimensions (berth or vessels) the berth is colored in gray. This indicates that no calculation was possible.
