Wish List

List of Wishes for future development of IWRAP

Topics raised at the IWRAP Training Seminar February 2010

Topics raised at the IWRAP Training Seminar in SYdney 2012

• Normalized result (Grounding frequency pr. sailed nm (i.e. Sum of length of all legs multiplied with number of passages)
• Add UNIX timestamps as an option
• ToYear multiplication factor should be derived from the relevant part of the AIS dataset only. i.e. one could import a dataset covering a very large area, but ones model will only be in one corner of the area. The ToYear factor should only be based on the data from a rectangle enclosing the model (all the legs of the model)
• Solve the Frequent Ferry Problem (number of vessels on a leg compared to number of passages)
• Make it possible to select certain parts of the AIS dataaset for an analysis (graphically)
• Legends on density plot
• Display leg length when it is being drawn
• One dialog box for all transparency controls
• Enhance seasonal variation analysis - Indicate sailed distance as function of time in a dataset.
• AIS Stream recording facility to gather data for IWRAP analysis.
• Near miss detection based on
• Auto detect need for splitting legs up due to SOG and/or lateral distribution variation

Older

The following items have been identified as possible developments of the free version of IWRAP Mk2:

Enhanced modelling/analysis capabilities

• Different Lateral Distributions for different Vessel types or Draft Classes (Challenge due to very many distributions)
• Possible to display the location of historical groundings and collisions (high priority)
• Possibility to define different area traffic to different parts of the model (Done)
• The lateral distributions should be displayed/represented as heading vectors. This will enable the analyst to determine if a leg should be divided into more than one leg. If a distribution contains a large spread of headings, the leg should be divided into two or even several shorter legs, or possibly even a set of crossing legs.(Done OFE/2012)

Polygon Improvements

• Ease polygon digitalization, polygon edit like Google Earth (Done OFE 2012)
• Ground polygon list (Done OFE/2012)
• Labelling of polygons (DONE OFE/DEC2009)
• Ground polygon color definition per depth (DONE OFE/DEC2009)
• Store ground polygons in separate files (in order to be shared between several models) (low priority)

Result view enhancement

• Graphical illustration of differences between 2 jobs (parked)
• Absolute chart scale (high priority)
• Enable display of partial results (done)
• Ranked list of collisions and groundings results, enable jump to leg, ground, waypoint in geographic result view (High Priority)

General Improvements

• Development tool - Migrate to Qt 4.5 (Done)
• Split and join leg (Done)
• Remove waypoints, combine legs (Done)
• Causation reduction factor change overview (High Priority)
• Model modification report, e.g. list causation changes (High priority)
• Reduction factor schemes (???)
• Plugin framework, causation factor, display overlay (High Priority)
• More information to manual about how to choose the value of mean time between checks when analyzing different sea areas
• Should be possible to modify mean time between checks for each leg individually (OFE/05DEC2009)
• Possibility to calculate with monthly traffic volumes (without multiplying volumes by 12 and then dividing results by 12) (Parked)
• Change job names or add comments to jobs after they have been completed
• Overwrite decimal zeros when keyboarding speeds and frequency adjustment factors in Traffic Volume Distribution Editor (done)
• Calculate overtaking and head-on collision frequencies per length unit of leg, not per leg (so that longer legs would not look riskier than shorter legs)
