V I I A 
Vessel Information Integrating Application

VIIA is a Web-based application where several end-users simultaneously can work together to inspect the vessel traffic in the world. 

The application is  designed and developed by TOP Software Technology.

VIIA runs on a server where administrated end-users can simply login on any platform using any HTML-5 compatible browser.

One can view and inspect live tracking information, but also go back in time to inspect situations in the past, since all information is stored. 

VIIA can automatically alert users when certain user-definable situations occur or has occured, for instance when a vessel is at risk (e.g. collision) or poses a risk (e.g. piracy, smuggling). 

VIIA can be used to help guarding coasts, ports, windmill area's on sea, offshore platforms, electricity cables  under the sea , internet cables, gas pipes, and the like. 

VIIA may be used e.g. by coast guards, customs, police, security departments, intelligence departments, windmill park owners, planning agencies, vessel fleet owners, and the like.

VIIA will be fine-tuned  by TOP Software Technology to meet your special needs. 

VIIA's Smart Vessel Information Integration Technique

  • Each day, millions of AIS transponder position reports are sent by ships and received by satellite and radar stations (S-AIS and T-AIS).

  • VIIA can process, integrate and store thousands of AIS  positions a second, millions on a daily base .

  • VIIA can even handle real-time Radar information to detect vessels without transponders, which is important in certain situations, e.g. when vessels are to close to a windmill farm at sea or unwanted Vessel manouvres take place.

  • VIIA can handle different types of Vessel Information tracking streams (S-AIS, T-AIS, radar) and uses a smart algorithm to fuse these information to identify Vessels, their Properties, and calculate their Tracks. 

  • VIIA's smart fusion techniques detects that information from different streams actually refers to one and the same vessel, but it can also detect that information from different sources is conflicting, or that the same identification is being used by different (!) vessels.

User-definable Filters (Views), Queries, Risk Profiling, and Alerts

  • VIIA offers a special language enabling end-users  to specify what kind of vessel properties they are interested in. VIIA's specification language reads like a natural language.

  • By using a drop-down menu, properties can be created. O nly meaningful properties can be constructed (it is type safe), given the choices made so far.

  • VIIA’s user interface is very user-friendly and intuitive, it has been developed in close collaboration with end-users and domain experts.

  • One can define the situations one is interested in, in terms of Vessel Properties (there are hundreds), Geographical Properties (user-defined area's, countries, harbours), or Tracking Behaviour. One can search for such properties in a particular point in time, or over any time interval.

  • VIIA 's specification language is one of the most powerful in the field and actively helps users to formulate meaningful queries , filters , views and / or risk profiles.

  • VIIA supports information-driven situation awareness: end-users can precisely define which kind of situations require attention.

  • VIIA  can automatically Alert end-users (e.g. via email) on the basis of fully customizable criteria (business rules) or risk profiles.

  • VIIA's  underlying Task-Oriented-Programming concept can be used to  further assist other people working in the organization with the follow up work that needs to be done when a critical situation is detected.

Risk Factors and Categories

  • VIIA supports the defintion of user-definable Risk Factors. Risk Factors can be combined in user-definable Risks Categories (e.g. a categorie could be "Environmental Risks").

  • One can define how much each Risk Factor is contributing to a risks of a certain Category.

  • When a Risk Category is chosen, VIIA replaces the standard view by a risk view to show which vessels impose a low, medium or high-risk for the chosen Risk Category.

  • VIIA shows the consequences when Risk Factors are being modified such that one can easily fine-tune definitions for achieving an optimal result.

New VIIA Features Are Under Development

  • VIIA is developed by TOP Software Technology  using  iTasks  Task-Oriented Programming   ( TOP ) .

  • iTasks is specifically designed for the development of distributed, web-based, multi-user applications. 

  • It allows us to rapidly add new functionality.

  • We work in close collaboration with you to add new functionality to VIIA based on your exact needs.
