The second IWRAP training seminar was held at St.Germain en Laye February 16-18, 2010.
A number of aspects of IWRAP were discussed at the seminar, some of which are documented below:
Lateral Distribution Tab With
Problem: (Igor PRARIO) When establishing a lateral distribution based on AIS data, you would obtain the basic distribution through numerical analysis of AIS data. For this you would need to select a with of each rectangular bar of the distribution, after which you would fit a suitable lateral distribution within the IWRAP tool.
The shape of the (mathematically) fitted distribution will change, depending on the width you select for the numerical analysis...
Question: Should the width of the numerical tabs not be selected carefully, perhaps as a function of the width of the ships passing the passage line?
Discussion: (Erik Sonne Ravn) Yes, your right, you need to experiment a little with the width of the tabs. If you make them to narrow, you will not get any distribution.
