Marine Spatial Data Infrastructure Development Framework: Croatia Case Study

Spatial data infrastructure (SDI) related to marine spatial data is known as marine SDI (MSDI). In this paper, we determine data themes under the MSDI in the order of usefulness and efficiency. The purpose is to streamline and support the prioritisation of data to be further implemented in the MSDI. This is conceptualised using the logic of decision support systems and a multi-criteria analysis approach that integrates components such as data, stakeholders, and users through multi-criteria methods for priority ranking. This research proposes an MSDI development concept and is validated using the Croatian MSDI case.

Stakeholders Needs Requisite Analysis: Towards Croatian Marine Spatial Data Infrastructure Establishment

National Marine Spatial Data Infrastructure (MSDI) in the Republic of Croatia has not yet been implemented. This paper examines the requirements and needs of future MSDI stakeholders, using a multidisciplinary approach. The paper describes the testing procedures, how to use the interview method, survey and research results. Survey sample was made up of providers and users of marine spatial data in Croatia, considering also future MSDI stakeholders (government and private sector, research institutions and non-governmental organizations). The aim was to investigate the needs for the MSDI implementation, which in Croatia doesn’t exist at the moment. However, results of our research show that the need for this kind of infrastructure is very high and justified. Results and collected information arewill be the basis for creation of the MSDI geoportal prototype.

A FRAMEWORK FOR EVALUATION OF MARINE SPATIAL DATA GEOPORTALS USING CASE STUDIES

Abstract Need for a Marine Spatial Data Infrastructure (MSDI) as a component of a National Spatial Data Infrastructure (NSDI) is widely recognized. An MSDI is relevant not only for hydrographers and government planners, but also for many other sectors which takes interest in marine spatial data, whether they are data users, data providers, or data managers [9]. An MSDI encompasses marine and coastal geographic and business information. For efficient use of Marine Spatial Data, it is necessary to ensure its valid and accessible distribution. A geoportal is a specialized web portal for sharing spatial information at different levels over the Internet. This paper re-examines the implementation of an MSDI and what it means for data custodians and end users. Several geoportals are reviewed (German and Australian) to determine their web services functionality, capabilities and the scope to which they support the sharing and reuse of Marine Spatial Data to assist the development of the Croatian MSDI Geoportal. This framework provides a context for better understanding the information bases on spatial data standards and a tool for evaluation of MSDI dissemination - Geoportal.
