Land and Sea Model

The Land and Sea Model Work Package's main objective was to develop Marine and Coastal Base Reference Information, or a digital base map, for the North Sea. Whilst countless datasets could be relevant for marine and coastal applications, "reference information" in this context refers to geographic datasets that are important when conducting activities such as: marine spatial planning; environmental protection; socio-economic development; risk management and mitigation.

The creation of Marine and Coastal Base Reference Information was achieved by working with BLAST Project Partners and marine and coastal data providers around the North Sea to facilitate making geographic data available for the widest possible use. Once the data was made available, its geometry and attribution were standardized and harmonized, removing the requirement for end users to reprocess the data. This was intended to reduce the time and cost requirements of end users.

With the completion of the Base Reference dataset, consideration was given to the coastline. The limits of geographic data capture and maintenance by a single organization in many instances lies at or around the coastline. Where data are managed across the coastline, it is often done without ongoing collaborative management between marine and terrestrial mapping authorities. As such, the mismatch at the coastline is considerable in most cases.

The Land and Sea Model aimed to develop strategies and proof of concept for harmonizing various base reference datasets at the coastline across four specific locations, in Norway, Denmark, Belgium and the United Kingdom.
