The Hydrographic Dimension of Marine SDI

The knowledge of spatial data is necessary for a large number of human activities. A Spatial Data Infrastructure (SDI) is a data infrastructure implementing a framework of geographic data, metadata, users and tools that are interactively connected. In Croatia much has already been written about SDI, but primarily from land-based perspective. In this paper marine dimension of SDI (MSDI) that encompasses marine geographic and business information in its widest sense is described. It is pointed out that hydrography, as modern applied science, plays very important role in measurements and description of oceans and seas. Hydrographic spatial data forms the key base reference layer for the sea space in MSDI data. There are a large number of MSDI stakeholders, but International Hydrographic Organization (IHO) recommends Hydrographic Office to play a central role in the development of the marine component of NSDI. It is concluded that MSDI in Croatia should be established according global, regional and national conventions and policies because Croatian internal waters, territorial sea and protected ecological and fishery zone (ZERP) area is 55 349 km2, what is 97.9% of Croatian land area.
