3 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma EU policies and GI Increasing interest for the spatial dimension: –GI-GIS needed (on an European level) to Assess needs Formulate the policy Monitor its implementation Evaluate its effectiveness Inform European Citizens,.... –GI-GIS explicitly required in EU directives/regulations Water Framework directive, Habitat, … Urban, Noise, …

4 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma But only islands … Data policy restrictions –pricing, copyright, access rights, licensing policy Lack of co-ordination –across boarders –between levels of government Lack of standards and their use –incompatible information –incompatible information systems –fragmentation of information –redundancy Lack of data In summary: no infrastructure EU has islands of data of different standards and quality...

5 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma INSPIRE INfrastructure for SPatial InfoRmation in Europe Need for action ! Without a co-ordinated framework as “minimum common denominator for all Member States” the problems will persist. INSPIRE launched in September

6 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma INSPIRE Framework Objectives & Principles –Make relevant, harmonised spatial data available for Community Environmental Policy (formulation, implementation, monitoring and evaluation) and for the citizen... –… through the establishment of integrated spatial information services, based upon a distributed network of databases, linked by common standards and protocols to ensure compatibility. –Linked to legal basis and policy measures –pan-European harmonisation of metadata / datasets / services (as far as necessary) in an European Spatial Data Infrastructure (ESDI)

7 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma INSPIRE Framework Scope –Existing digital spatial data (exception: essential datasets) –Public sector –Protection of the environment, Sustainable development, Integration Data policy –licensing framework for sharing between public bodies –Publish, discover and view services free of charge –no charging constraints on access Implementing provisions –Establishment of Committee, Monitoring and reporting –Stepwise approach

8 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma INSPIRE principles 1.spatial data should be collected once and maintained at the level where this can be done most effectively 2.it must be possible to combine seamlessly spatial data from different sources across the EU and share it between many users and applications 3.it must be possible for spatial data collected at one level of government to be shared between all the different levels of government 4.spatial data needed for good governance should be available on conditions that are not restricting its extensive use 5.it should be easy to discover which spatial data is available, to evaluate its fitness for purpose and to know which conditions apply for its use.

15 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Interoperating GI services in EU RSDI A cross border study Background Discussions with stakeholders on realizing a NRW- NL cross border GDI since almost one year Technical Workshop in Ispra in Jan on connecting European RSDI  showed that only a few cross-border linkages can be realized in the moment

16 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Interoperating GI services in EU RSDI Cross Border RSDI Study (March - June 2003) Funded by EU-INTERREG, NL, and NRW: A)Study on different stakeholders and their needs on a cross border SDI B)Organization plan for a sustainable cross border SDI C)Pilot on easy-to-reach cross border SDI applications D)Presentation of the results on the 2nd NRW-NL Geo-Conference in June 2003 (Münster)

17 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Interoperating GI services in EU RSDI A cross border study Objectives Prove and demonstrate the applicability of state of the art technology and GI standards: –proving that it is simple and easy to achieve –proving that technology and standards are practical and applicable, experience is available –proving that Cross Border partnership leads to better results –reporting the current technical potentials of cross border RSDI and the open development and research issues –apply the INSPIRE recommendations

18 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Cross Border RSDI Prototype Scope of the Pilot: Offering cross border geo-information by providing cross border Web Mapping Services (WMS) and Web Catalog Services (WCatS) Providing topographic data and road data by different WMS Accessible through universal clients in HTML-browser and allowing seamless usage of linked WMS

19 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Cross Border RSDI Prototype Technologies Publish Find Bind Search Engine Information Resources Internet

20 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Cross Border RSDI Prototype Technologies Web Catalog Service (WcatS): Standardizes the way a client searches for metadata descriptions on spatial data or services Parameters include the query language used, the desired verbosity of the result, etc. Catalog servers manage metadata descriptions based on a metadata schema, e.g. ISO Basic operations: –GetCapabilities –TransactionService –GetRecord –DescribeRecordType

21 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Cross Border RSDI Prototype Technologies OpenGIS Web Map Service (WMS) Standardizes the way in which clients request maps Parameters include: named layers, size and area of the returned map, spatial reference system, etc. A WMS has 3 operations: –GetCapabilities –GetMap –GetFeatureInfo

25 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ In the Netherlands a case of food-and-mouth-disease has been detected.

26 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ This case is added to a web-accessible map server (*) by a veterinary from the Dutch environmental authority (*) the MKZ map server; food-and-mouth-disease is “mond en klauwzeer” in dutch Operator NL WMS - MKZ Data NL Geodan

27 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ The Dutch veterinary calls its German colleague in North- Rhine Westphalia to inform him about the developments and discuss measures

28 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ The German veterinary in North-Rhine Westphalia starts his Web Browser and opens a Cross-Border GDI Portal

29 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ He opens a catalog client to search for information about the food-and-mouth-disease in Gelderland He uses the keywords: „Gelderland Maul- und Klauenseuche“ … and finds the “mond en klauwzeer” map server in the Netherlands (due to the availability of multi-language metadata)

30 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ The veterinary in North-Rhine Westphalia opens his favourite web mapping client He adds the MKZ-Layer from the map server found by his search WMS Client IfGI WMS - NUTS NL Geodan WMS - MKZ Data NL Geodan

31 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ The veterinary sees a map with one or more symbols representing MKZ cases He clicks on one symbol to retrieve additional information about the particular case

32 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ The veterinary now uses the catalogue client again to search for road data in both the Netherlands and North- Rhine Westphalia

33 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ He finds two map servers and adds layers from these servers to his map

34 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ Together with his colleague in the Netherlands he identifies a location that needs closer inspection (the closest border crossings from the reported cases where control points shall be established; no control points on highways)

35 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ As he zooms in to this area, more details are shown on the map (topographic layers) Both operators can now identify and discuss in detail where the control points should be established, etc.

36 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ After the discussion is finished and the measures have been agreed upon, both veterinaries continue to communicate with the required authorities in their region (e.g. police, road administration, etc.) In order to do this successfully and efficiently, a presentation of the same information in the native language of the respective region is essential  support for multiple languages is a key aspect for cross-border activities

37 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ The situation as seen by the operator in the Netherlands

38 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Showcase NL-NRW „Cross-Border Risk Management“ The use of open specifications allows the integration in standard GIS products, too

39 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma EU Geo-Portal - Motivation Recommended by –INSPIRE WGs Architecture and Standards and Implementing Strategy –GINIE Project –Supported by the INSPIRE Internet consultation One entrance point to the up-coming ESDI to support the search and access to geoinformation resources in the ESDI Evaluation and demonstration of current developments and their potentials Motivation of national and regional SDI-development

40 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma EU Geo-Portal Does not contradict the Idea of the ESDI, being based on distributed geoinformation services (  INSPIRE-consultation) A Geo-Portal realizes a thematic and/or regional view on the SDI (environmental portal, national portal, etc.). Has an important teaching, learning, and motivation effects :  what happens ?  what is already feasible ?  who is already taking part ? (= my GI resources should also be connected)

41 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma EU Geo-Portal - Requirements In chronological order (1/2): Based on distributed geodata & GI services (no local copies…) ! Publish and search geoinformation Access to further relevant resources (Documentation, FAQ, links,…) Integration of distributed portrayal services (Web Mapping Services) Provide multilingual Thesauri and Gazetteer

42 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma EU Geo-Portal - Requirements In chronological order (2/2): Multilingualism  Application, Thesauri, Metadata, Attribute identifiers of geodata or services… …up to which granularity ?!? Support of AAA services (Authorisation, Access, Account); perhaps Pricing- and Ordering Services user profiles Access on further geoprocessing services (classification, coordinate transformation, etc.) and GI service chaining according to user needs

43 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma EU Geo-Portal - Components Web Browser (Thin Client)

44 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma EU Geo-Portal - Prototyp Requirements for the prototype: Publish of Geoinformation (geodata and GI services) by registering metadata Search for geoinformation Access to further relevant resources (Documentation, FAQ, links,…) Integration of distributed portrayal services (Web Mapping Services)

54 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Add new WMS (CORINE Land Cover)

55 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Conclusions Major Achievements: –Up-to-date geo-information is available across borders / pan-European using existing GI-specifications and standards –Collaboration is possible on a shared and common information level –(Low-key) semantic interoperability is achieved through the use of mapping services –No pre-installed software is required, just a web browser and an internet connection

56 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Conclusions What was required to make these applications work: –Usage of common technical specifications and standards Web Map Service Catalog Service Common base information models and their encoding –Availability of the required datasets via the internet –All services support a common Coordinate Reference System (CRS) –Multi-language support in Web Map Services and the metadata

57 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Issues / Lessons learnt In a European context, built-in support for multiple languages is required in technical specifications like Web Map Service and Catalog Service The higher the structural and semantical similarity of the information on both sides of the border, the easier it is to exploit cross-border data (e.g. layer classification) Integration by mapping does result in maps with heterogeneous mapping styles  not necessarily a problem

58 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Issues / Lessons learnt Metadata… –Lack in collecting and providing of Metadata - thus use of metadata can hardly be proven –Further need on tools to support (semi-) automatic collection and maintenance of metadata –Missing support to combine ISO and 19119; Standards not always sufficient –Multilingualism –Harmonising Of used Schemata und Categories Used Vocabularies in Thesauri and Gazetteer (  semantic Interoperability)

59 Interoperabilità nelle Infrastrutture di Dati Territoriali, 26. Feb. 2004, Roma Issues / Lessons learnt ISO-Standards and OGC-Specifications are a good & important tool for Interoperability, but it needs some additional glue… –Definition of CRS, Scale-Hints, layer names… –Certification of services (  CITE) –Quality measurement of distributed(!) services –Long-lasting Specifications  ESDI Technical Guidelines; support to harmonise additional specifications on European level  Futher development of specifications (incl. feedback to ISO & OGC !!) by European and national SDI-Projects
