Interoperable, standardised and adequate tools are important for coastal zone management and maritime safety. In respect to geographic data, it is a fundamental problem that data on the landward side is collected and maintained by topographic mapping or cadastral agencies and is utilised primarily for development, nature conservation etc., while sea data is collected by hydrographical survey services and focuses primarily on marine navigation issues. Furthermore, the collaboration between member states at national, regional and local level can be improved.

BLAST is also represented in the MTC cluster.

Aim
The overall aim of the project is to improve Integrated Coastal Zone Management and Planning (ICZM&P) and maritime safety in a broad sense, by improving and contributing to harmonising terrestrial and sea geographical data and by developing planning and visualisation tools as well as improvement of navigation, in the context of climate change.

Background
The Operational Programme states with emphasis that future economic development goes hand in hand with environmental consciousness. There is competition for use of the coastal zone, and there is a common challenge to find positive solutions where social, economic and environmental development pressures come into conflict. The BLAST project has a primary focus on “Bringing land and sea together”, by harmonizing and integrating data for land and sea.

In respect to geographic data, it is a fundamental problem that data on the landward side is collected and main-tained by topographic mapping or cadastral agencies utilised primarily for development, nature conservation etc., while sea data is collected by hydrographic survey services, focusing primarily on marine navigation issues.

Furthermore, the collaboration between member states at national, regional and local level can be improved. This can lead to seamlessly joined data which gives consistent information without overlap. BLAST will follow the IHO-guidelines as state of the art. The outcome of the project will be a regional input to the IHO-organisation (International Hydrographic Office). There are also areas not covered, especially in shallow water. These problems implies a limitation to good planning and integrated coastal zone management, and it poses a risk in handling acute pollution, accidents etc. The project will therefore provide a prototype for land/sea interoperable database for testing by practitioners in a study area.
It is a transnational European challenge to harmonise maritime information. One special aspect is safe approach and berthing of ship in ports. Today, maritime information is presented in different ways in different ports and different countries. The project will develop a basis for harmonising maritime information. It will also demonstrate the value of 3D visualisation in navigational aid displays. Incomplete, inconsistent maritime information is a leading factor in marine casualties, environmental damage and ship detainments. The process will build on the work already made in The Baltic Sea Harmonisation Working Group.

Lack of reliable maritime information will always be a risk in respect to the maritime traffic navigation and monitoring. A harmonised ENC (Electronical Nautical Chart) system and efficient traffic monitoring system are of utmost importance to keep a high level of security for regional maritime traffic. Integration and distribution of maritime data is therefore important. It is also important to widen access (SafeSeaNet) to these data so that all parties involved in traffic management can use the data to improve decision making. BLAST will in part improve the functionalities of databases, and it will provide input to improve SafeSeaNet.

The coastal zone is an optimal place to locate renewable energy devices (wind, tidal turbine) while at the same time needing to consider other interests like maritime traffic and vulnerable ecosystems. These interests need to be managed in a context of climate change adaptation. Consequently integration of coastal zone data for planning and management becomes prominent. The project will develop a conceptual model for integrated spatial planning utilising GIS, tools for spatial planning in respect to renewable energy plants, and a Web based decision support system for ICZM in a transnational context. The SEA principles will be used to ensure impacts are adequately considered.

An important premise for improved ICZM is to link sea and land areas together. Hence, an important aspect of the aim is to structure and supplement geographical data and provide planning/management tools that are consistent between sea and land.
