A framework for the evaluation of marine spatial data infrastructures - Accompanied by international case-studies
Germany is currently developing a marine data infrastructure addressing different topics such as coastal engineering, hydrography and surveying, protection of the marine environment, maritime conservation, regional planning, and coastal research. This undertaking is embedded in a series of regulations and developments at many administrative levels, from which specifications and courses of action are derived. To set up a conceptual framework for the marine data infrastructure of Germany (MDI-DE), scientists at the Chair for Geodesy and Geoinformatics at the Rostock University are building a reference model, evaluating meta-information systems and developing models to support common workflows in marine applications.
Evaluating how other countries built their marine spatial infrastructures is important to learn where obstacles and errors are likely to occur. To be able to look at other initiatives from a neutral point of view, it is necessary to construct a framework for evaluating marine spatial data infrastructures (MSDI). This framework is then used to analyse and evaluate the efforts of Canada, Australia, and Ireland with respect to marine data infrastructures
Informacije i raspon baza podataka koje se koriste za pomorsko prostorno planiranje i za integrirano upravljanje obalnim podruÄjem - primjer sluÄaja u Poljskoj, BaltiÄko more
Intensive exploitation of coastal and maritime areas, together with climate changes, natural hazards and erosion, have increased pressure on coastal and maritime resources. They require
integrated and consistent management in order to ensure sustainable development and to preserve coastal and marine ecosystems for future generations. Spatial development planning for maritime
areas is commonly understood to denote an open process of analysis, planning and temporal distribution of components of human activity, which results in accomplishment of economic, social and
environmental goals. Such actions require a wide range of information. The main objective of the study was to identify the range of data used in maritime spatial planning, integrated coastal zone management in the Polish part of the Baltic Sea and the possibility of acquiring such data. A high degree of generalisation prevents a lot of available data for MSP and ICZM from being used. An analysis of information resources (databases, registers, information systems) for the Polish Baltic zone and the coastal area has shown it to be dispersed and incomplete. However, considering the rapid development of the sector and the commitment of the stakeholders, one can predict that the new tools and projects will fill the gaps in this regard.Intenzivna eksploatacija obalnih i morskih podruÄjima, zajedno s klimatskim promjenama, prirodnim nepogodama i erozijom, Äine poveÄan pritisak na obalne i pomorske resurse. Ovi resursi
zahtijevaju integrirano i konzistentno upravljanje kako bi se osigurao odrĹživi razvoj, te omoguÄilo oÄuvanje obalnih i morskih ekosustava za buduÄe generacije. Planiranje prostornog razvoja pomorskih podruÄja obiÄno podrazumijeva otvoren proces analize,
planiranja i vremenske raspodjele dijelova ljudskog djelovanja, ĹĄto rezultira provoÄenjem ekonomskih, socijalnih i ekoloĹĄkih ciljeva. Takvi postupci zahtijevaju ĹĄirok raspon informacija. Glavni cilj
naĹĄeg istraĹživanja bio je utvrditi raspon podataka koji se koriste u pomorskom prostornom planiranju, integriranom upravljanju obalnim podruÄjem u poljskom dijelu BaltiÄkog mora, kao i moguÄnost
stjecanja takvih podataka. Visok stupanj generalizacije sprjeÄava koriĹĄtenje veÄine raspoloĹživih korisnih podataka za MSP i ICZM. Analiza informacijskih izvora (baze podataka, registri, informacijski sustavi) za poljski dio BaltiÄke zone i obalnog podruÄja pokazala je da su podaci rasprĹĄeni i nepotpuni. MeÄutim, s obzirom na brzi razvoj sektora i predanost sudionika, moĹže se predvidjeti da Äe novi alati i projekti doprinjeti rjeĹĄavanju problema s podacima

Ethernet - a survey on its fields of application
During the last decades, Ethernet progressively became the most widely used local area networking (LAN) technology. Apart from LAN installations, Ethernet became also attractive for many other fields of application, ranging from industry to avionics, telecommunication, and multimedia. The expanded application of this technology is mainly due to its significant assets like reduced cost, backward-compatibility, flexibility, and expandability. However, this new trend raises some problems concerning the services of the protocol and the requirements for each application. Therefore, specific adaptations prove essential to integrate this communication technology in each field of application. Our primary objective is to show how Ethernet has been enhanced to comply with the specific requirements of several application fields, particularly in transport, embedded and multimedia contexts. The paper first describes the common Ethernet LAN technology and highlights its main features. It reviews the most important specific Ethernet versions with respect to each application fieldâs requirements. Finally, we compare these different fields of application and we particularly focus on the fundamental concepts and the quality of service capabilities of each proposal
