In recent years, the number of geoportals was constantly increasing all over the world. In Poland, the main reason of growth is implementation of the INSPIRE Directive. The most important goal of creating geoportals is to provide Spatial Data for the Polish Spatial Infrastructure (Głowacki et al. 2005). Theirs architecture is oriented to services and interaction with any user (Akinci & Comert 2008). All technological solutions should give the user the possibility of using data from many sources in one platform (Nowacki & Opach 2009). Most of Geographic Information Systems represents only the view of the "bird's eye" without giving the possibility of three dimensional viewing of the actual situation on the ground. What you can see is the land surface as an object map or ortophotomap. However, currently a demand of GIS applications designed for fully three-dimensional data is growing. This approach is commonly used for presentation and spatial analysis (Scianna 2013). Thanks to the modern capabilities, ensuring high quality of three-dimensional models is easy (Shioda 2000). Geoportal AGH - Spatial Information System of the AGH University of Science and Technology - was established in order to provide updated data, allowing moving around the campus. This functionality has been ensured by the construction of site (geoportal). The combination of a vector map along with a number of tools allowing searching by attribute makes it possible to search for any building or room available for students' classes. Geoportal AGH will also include data on the news and current events related to the life of the university, for example: repairs of roads, conferences and recruitment. All this is available in a modern, interactive application that was created based on the latest technologies for maximum usability and support for each user. Now in progress is the creation of three-dimensional model of the AGH campus and its implementation on the mentioned above server www.gis. agh.edu.pl becoming its integral part. The work involves the use of data obtained from surveying and external facade images of objects in order to create a model resembling the real and its rendering. Contractors of the grant will be students of the Faculty of Mining Surveying and Environmental Engineering. Substantive support to the project was provided by our partner - ESRI Poland. Through the financial support of the Scientific Society named after Stanisław Staszic we can present our achievements in the international area.

W niniejszej pracy omówione zostaną szczegółowo etapy projektowania i implementacji „Geoportalu AGH”. Pierwsza część artykułu dotyczy idei, a także opisu prac przygotowawczych i projektowych Systemu. Następnie omówiony został proces pozyskiwania danych przestrzennych i opisowych, które były podstawą do utworzenia wektorowego modelu kampusu AGH. Szczególną uwagę poświęcono również bazie danych, przedstawiając jej strukturę i rozwiązania pozwalające na jej integrację z systemami przechowywania danych osobowych. W pracy przedstawiona została również metodyka tworzenia sieci dróg w przestrzeni trójwymiarowej, stanowiącej jedno z narzędzi udostępnianych w sieci, wraz z opisem działania na serwerze. Ponadto szczegółowo opisany został projekt aplikacji typu WebGIS, stanowiącej warstwę prezentacji Geoportalu, utworzony przy użyciu technologii ArcGIS API for Silverlight. Na koniec przedstawione zostaną plany dotyczące wdrożenia nowych funkcjonalności, o które ma zostać rozbudowany serwis.

In this paper we present stages of design and implementation of Geoportal AGH for the AGH University of Science and Technology. First part of the paper relates to the idea of the project and description of the system design. Next, we discuss the process of acquiring spatial data and descriptive data, which provided the basis for creation of a vector model of AGH campus. Particular attention was also devoted to the database structure and solutions allowing its integration with personal data storage systems. The paper also presents methodology of creating a network of roads in three-dimensional space, which is one of the tools available in the internet together with the operation instructions. In addition, a design of WebGIS application is described, constituting a layer of Geoportal presentation, created with the use of ArcGIS API for Silverlight. Finally, we discuss future plans of implementation of new functionalities to extend our services.
