2 Presentation Overview SDIs for the MED Islands Matching analysis 3D geo-portal 2/ 29

3 SDIs for the MED Islands (1) The Article 158 of the Treaty of Amsterdam and the EU Island Regions The EU Islands and the promotion and strengthening of their Information Society Technologies The EU Islands Spatial Data Infrastructures 3/ 29

4 SDIs for the MED Islands (2) Barriers that Medisolae-3D aims to overcome: gaps and duplication of spatial data poor quality of datasets seldom use of data standards lack of metadata lack of interoperability of existing geographic information services incompatibility of different GI initiatives lack of data sharing and re-use different motivation and interests in SDI use procedural, legal, financial and institutional barriers between public and private bodies related to the access and use of geodata 4/29

5 SDIs for the MED Islands (3) Implementation of the MedIsolae-3D spatial data infrastructure using ESRI ArcGIS 9.3: Harmonization of the spatial datasets of the numerous Med-islands Improvement of the usability and accessibility of standardized spatial information. The design and realization of the SDI started with the harmonization of the various datasets provided by the project partners, including: 5/ 29

6 SDIs for the MED Islands (4) Identification of feature classes in line with the INSPIRE themes (in Annexes I and II of the Directive) and feature classes of non-inspirethemes Definition of a structure of the feature classes that is compliant as much as possible with the applicable standards Definition of attributes for each feature class Assistance to the Med-islands data-providers, including instructions on CRS and metadata standards Development of the GDB (Geodatabase) 6/ 29

7 SDIs for the MED Islands (5) MEDISOLAE-3D Feature list POIs 3D buildings NON-INSPIRE THEMES INSPIRE THEMES Admnistrative units (Ann. I) Transport networks (Ann. I) Hydrography (Ann.

10 SDIs for the MED Islands (8) Elevation Contour lines Hydrography Aquifers Channels Rivers Lakes Reservoirs River Basins River Sub-basins Land Cover Protected sites 10 / 29

11 SDIs for the MED Islands (9) Transport networks Airports Ports Data model excel file November 2008 Structure of the feature class 3d-buildings Very complex data model Source data collection on-going by project partners 3D City Model technology by Cybercity The 3D city model for the Santorini Island was provided to the MedIsolae-3D project by CyberCity in two formats: ESRI multipatch KML 11 / 29

14 SDIs for the MED Islands (11) Just few examples related to the compliance of the MEDISOLAE-3D SDI to INSPIRE: Available since Annex I Data Specifications (by INSPIRE Drafting Team and Thematic Working Groups) Adoption of the requirements (change CRS from WGS84 to ETSR89) Adoption of the recommendations (as much as possible) Matching analysis of the data models Tracking of the testing & consultation activities (registration of the MEDISOLAE-3D SDIC) 14 / 29

17 3D geoportal (1) Many functionalities, all integrated 17 / 29

18 3D geoportal (2) 18 / 29

19 3D geoportal (3) Eight different options are currently under deep investigation for the integration of the 3D WebGIS technologies into the overall geoportal system architecture, all of them aiming at optimizing the geoportal performance in terms of the following user requirements: Clients thin as much as possible, able to consume the (even complex) services published on the server-side. Compliance with the networking services and interoperability standards & requirements of INSPIRE. Compatibility with the MedIsolae-3D portal layout & overall architecture (yassoo ), which in turn needs to be potentially linked to Web-geoplatforms like Google Earth, MS Virtual Earth and ESRI ArcGlobe. 19 / 29

26 3D geoportal (10) Islands SDI spatial data services and networking services (ESRI technologies) (3) Hardware characteristics of the project server: RAM 8GB, cache memory 12MB, processor Quadcore Xeon GHz Operating System: Windows 2008 Server Web server: IIS 7.0 Mapserver: ArcGIS Server 9.3 Enterprise Edition, which publishes as mapservices all the SDI spatial datasets present in the data model described in the previous section, authored in turn with ArcGIS desktop 9.3 version ArcView. 26 / 29

27 3D geoportal (11) Islands SDI spatial data services and networking services (ESRI technologies) (3) Interoperability: a WMS has been created for all the published SDI spatial datasets Any GIS client/viewer supporting the WMS capability (such as Quantum GIS, udig, ArcGIS Explorer and many others, most of them freely available) can access the Santorini SDI spatial datasets simply by selecting the option Add an external WMS service and typing the corresponding url mxd/mapserver/wmsserver/ 27 / 29
