Vessel Transmitted Information VRE
Introduction
The Vessel Transmitted Information VRE (VTI) has its roots in requests by the United Nations General Assembly (UNGA) to generate fishery statistics that distinguish catches within and outside the EEZs, and of the Coordinating Working Party on Fishery Statistics (CWP) to improve the quality of global catch statistics.
The goal of VTI is to improve the sharing and analysis of fishing activity datasets.
VTI will be a VRE for marine biologist that want to analyze vessel activities over space and time, and integrated with environmental data. Since vessel data are often confidential, the VRE also allows the data owners to aggregate data over space and time in order to make them anonymous before they can be accessed by others.
The VRE will offer three main components:
1. Time-series management and confidentiality features, to load, curate and aggregate data. This part of the VRE will re-use ICIS components;
2. Plotting and visualizing data, to visualize the Time-series as tracks and / or effort per area. The facilities developed for the AquaMaps VRE can be re-used.
3. Interoperable access to an environmental data-infrastructure (GENESI-DEC) to produce compound products with a spatio-temporal context. The products will be Time Series with a clear geospatial and environmental context. These will also be harmonized, facilitating their re-use in external applications, and the sharing of datasets between Regional Fisheries Bodies (RFB’s).

For RFB's with advanced information management capabilities, the VRE offers the possibility to compare/share information across domains using standardized formats. An example would be to obtain a combined aggregation of fishing effort for pelagic redfish in areas 1F (NAFO) and XII (ICES). In addition, D4Science provides access to a wide range of environmental datasets through GENESI-DEC. The VRE can combine these with vessel related information in a single product that allows for a truly cross-domain analysis in space and time.
For RFB's or other institutions that lack in-house data-management capacity, the VRE can help improve data quality, ensure data integrity and provide access to currently closed data repositories. In addition, it bundles GIS and statistical functionality, and is a very cost-effective solution if spatial and environmental analysis is required.
Re-use of existing D4Science resources will have to prove the development concept of D4Science, where sharing services and data resources promise to reduce development effort. ICIS components will be used to manage VTI time-series data, AquaMaps services will allow the rendering and analysis of data on maps, etc..

Objectives
The VTI framework aims to offer scientific analytical capabilities on existing VMS data, either in their raw format, or on aggregated datasets. The scientific analysis shall allow statistical and geospatial analysis within and across selected datasets. The products shall be defined in a set of use-cases that can be implemented using D4Science technologies. These may include:
- Provision of geo-spatial datasets derived from one or more VTI datasets over a specified time-period, and aggregated over space;
- Analysis of trends, clustering, and frequencies in and across VTI datasets;
- Integrate VTI data with Genesi-DR derived environmental data;
- Mapping and publishing of datasets as sharable (geospatial) products..
Active collaboration has started in February 2011, and will continue until the end of the D4Science project. Total effort from the D4Science-II is estimated to exceed 8 person months.
