METADATA AND CATALOGUEA revival in awareness of the importance ofgeography and how things relate spatially, combinedwith advancements in electronic technology, has caused aworldwide expansion in use of digital geographicinformation and geographic information systems (GIS).People from a wide range of disciplines outsidegeographic sciences and information technologies areincreasingly capable of producing, enhancing, andmodifying digital geographic information.A Catalogue is simply a collection of 'entries' that isorganized to assist in the discovery, access, and retrievalof geospatial resources that are of interest to the user,especially when the user does not know the existence orwhereabouts of the resource. Being a collection ofcatalogue entries, a catalogue should be able toenumerate each of its entries, and should allow entries tobe added or removed. It should also support queries thatwill enable the user to obtain entries of interest based onspecified criteria.The important task of NNR portal is to supportcombined search for spatial and non-spatial information.Therefore, the decision was to implement two systems,which combine ISO19115 standards for spatial data andDC for non-spatial data.The solution is based on MIcKA metadata systemdeveloped by HSRS (member of OGC) (see Figure 1).For the search of textual, multimedia and educationalcontent, projects and tools, the Dublin Core metadatamethodology that is implemented in the MIcKAcatalogue system will be used. The specific profiles ofDC metadata will be prepared for information searches.The integration of a Thesaurus (AgroVoc) and Gazetteersbased on NUTS 5 European level supporting localisationof information is recommended. For the search forGeospatial information, the ISO19115 metadata model(respective implementation scheme 19139) that isimplemented in MIcKA will be used.Figure 2. Map Designer layout.The following part of the catalogue is Map DesignerMapMan (see Figure 2) supported:• Search for spatial data (see Figure 3);Figure 3. Spatial data search in MapMan.• Definition of the composition of spatial data(see Figure 4);Figure 4. Spatial data processing.Figure 1.

SPATIAL INFORMATIONFor the visualisation of spatial data, the open sourcesoftware MapServer, developed by University ofMinnesota (USA) within the frame of a NASA grant, isused. The MapServer output is a raster map in GIF, PNG,JPG (for Internet browsers of personal or pocketcomputers) or WBMP formats (for mobile phonessupporting WAP), and optionally PDF or GML vectorformat. Our applications use the wide range ofpossibilities provided by MapServer. Two clients areimplemented. For professional work, it will be JavaScript clients. For the work of non-specialists and forintegration with e-learning application, a DHTML clientwill be used.E-LEARNING PLATFORMNNR aims to promote the concept of SD through theInternet by providing innovative tools and web services.The concept of SD will be demonstrated throughexample use case scenarios in test regions associatedwith the NNR project as well as at the European scale.The scenarios are embedded in an e-learningenvironment that guides the user through structured usecase modules.The focus of this part of the NNR project isvisualisation and use of geographical data since theenvironmental component of SD has a stronggeographical relationship. Geographical information ispresented in 2D by the open source Minnesota MapServer that will be implemented into the e-learningplatform ILIAS. In addition to that, this data will also beaccessible by a 3D viewer that provides additionalinformation about the terrain.These courses will be established for each test regionthereby presenting the specific challenges for SD. For alltest regions, a variety of geographical data is availableand already implemented on the web server. Economicdevelopment, e.g. in terms of industrial growth or just theincrease of urban areas, can have negative effects on theenvironment and society if this process is not managed.Planners require appropriate tools for the sustainablemanagement of geographic areas that provideinformation about the potential effects on theenvironment in advance. For this reason a NNR-specificSustainability Impact Assessment, based on theprinciples of the Environmental Impact Assessment, willbe provided as a learning module with the aim tosensitize the user to the potential impacts of physicaldevelopment projects with regard to their environmental,social and economic parameters. The module will containinteractive matrices that enable the user to rate the impactfor each parameter. In this context, the geodata withenvironmental, social, and economic relation provide theinformation required for such an assessment. In additionto the application in the web portal, mobile devices willbe applied in an outdoor environment in order to verifyand/or add actual data to the database of the system.3D-PRESENTATION OF SPATIALINFORMATIONAccording to the requirements of the project a realtimelandscape visualisation that allows the integration ofadditional multimedia information was realised. Nolicense cost, as well as the technological possibilities andthe performance were the main reasons to select theShockwave3D solution for the real-time visualisationmodule. The 3D-presentation of spatial data is animportant and impressive part of the informationpresentation in the e-learning applications. The 3Dpresentationconsists of a 3D-viewer, which is very easyto handle, and which shows the three-dimensional spatialdata models to the user. This 3D-viewer is developedusing Macromedia Director 8.5.Figure 5. Shockwave3D solution for spatial datapresentation.The 3D-models are built up from existing geo-datasources using standardised web-services for the geo-dataexchange. Figure 5 shows a prototype of the 3D-viewer,which contains navigation elements (pan / zoom / rotate)as well as an overview map and additional informationbuttons (Almer et al., 2004).INTERACTIVE MULTIMEDIA EVENTSOne of the NNR project goals is to build a simple andflexible portal component which: provides organizingand conducting of multimedia events where participantsare allocated remotely; uses Internet as a tool via userfriendly NNR portal interface; uses inexpensive andwidespread hardware and software components.A multimedia event allows individuals or groups tomeet face-to-face in real time to interact andAnnual Proceedings of Vidzeme University College “ICTE in Regional Development”, 200639
