  1. Geographic Information Technology Training Aliance Which place for Spatial Modelling in GIS education? The example of the GITTA project LASIG laboratory Corinne Plazanet & Regis Caloz Sept. the 13th 2002

  2. Geographic Information Technology Training Aliance Outline The GITTA project Pedagogical objectives and content Spatial Modeling modules Integration within the GITTA curriculum Conclusion and open questions EPFL – LaSIG lab. C. Plazanet & R. Caloz

  3. The GITTA project Swiss Virtual Campus project 07/2001 - 01/2004 • Covers 1 discipline: GIS • 4 languages • 10 academic partners: • Universities, high schools, • Federal Institutes of Technology • + 1 administrative partner + 1 pedagogue 85% of the capacity of GIS academiccourses in Switzerland EPFL – LaSIG lab. C. Plazanet & R. Caloz

  4. Target public Universities, high schools, Federal Institutes of Technology • Students in geography, geomatics (geodetics, topographic works), forestry sciences, computer science, land use planning • Applied sciences (biology, earth sciences, biology, land architecture… ) • Postgraduate diploma • Formation continue EPFL – LaSIG lab. C. Plazanet & R. Caloz

  5. Objectives • Federate knowledge in GIS in a virtual campus with coordinated curriculum • Standardize course structure and contents by exploiting synergies and eliminating redundancies • Provide a virtual learning center that allows students to complete standardized ECTS units • Integrate GITTAcourse units in existing curriculum in order to replace or enhance traditional courses (pedagogical renewal) Declared objective: Presence in classroom reduced to 50% (tutoring sessions, project reviews, working groups, student presentations, etc.) Main 1rst interest: provide a GI curriculum up to date and well structured EPFL – LaSIG lab. C. Plazanet & R. Caloz

  6. Pedagogical and didactical objectives • Develop student independence in his learning process • Develop his capabilities in GIS management for the analysis of simple spatial issues within an individual learning environment based on information technologies • Integrate transdisciplinaryaspects of GIS knowledge and emphasize consciences on practical issues by working on real world case studies • Deepen specific topics through projects The success of the approach lies not only on didactical tools but also on coaching and tutoring ! EPFL – LaSIG lab. C. Plazanet & R. Caloz

  7. Modular pedagogical approach 2 Decision making 3 3 3 2 Optimal route in urban road netwk 2 Gaz pipeline: pattern optimization 2 ECTS / curriculum 1 ECTS = 2 days 2 Terrain elevation of yarding Cachment and hydrology modeling 2 1 Implementation of a business GIS 1 Geomarketing 2 1 1 1 1 1 ECTS = 30 hours EPFL – LaSIG lab. C. Plazanet & R. Caloz 0.5 0.5 0.5 1 0.5 1 Large place for theoritical aspects

  8. Spatial modeling basic module Module -> lessons -> units L1: Spatial perception and modeling U1:Terms and definitions U2: From reality to representations U3: Conventional spatial modeling: maps U4: Models of apprehension of geographical space L5: Conceptual data modeling U17: Concepts of conceptual modeling U18: The Entity-Relationship model U19: Spatial conceptual data models L4: Numerical modeling of reality U10: Introduction to numerical modeling U11: Concepts of vector model U12: Topology U13: Concepts of raster or image model U14: Comparison of vector / raster U15: Relief modeling (DTM) U16: Network modeling L2: Fundamental concepts U5: Scale U6: Georeference: Location, projections U7: Spatial relations: Distance U7: Spatial relations: Topology EPFL – LaSIG lab. C. Plazanet & R. Caloz L3: Notions of information modelling U8: Units of observation of reality U9: spatial information

  9. Spatial modeling intermediate module Module -> lessons -> units L1: Advanced relief modeling U: MODELS U: RELIEF PROPRIETES L6: Information System Engineering U: DESIGN METHODOLOGIES U: PROCESS MODELING (DATA FLOW) U: CONCEPTUAL DATA MODELS U: CASE TOOLS U: SPATIAL DATA INFRASTRUCTURES U: META DATA U: EXCHANGE FORMATS: INTERLIS L2: 2.5D, 3D Modeling L3: Advanced network modeling L4: Specific models U: MODELS FOR SPATIAL ANALYSIS  U: STRUCTURES FOR DB INDEXING U: STRUCTURES FOR DATA COMPRESSION L5: Multi source GIS - Interoperability U: MULTIREPRESENTATION MODELING CONCEPTS U: DB INTEGRATION (INTER SCHEMAS CORRESPONDANCE ASSERTIONS) U: ABSTRACTION MECANISMS - GENERALIZATION EPFL – LaSIG lab. C. Plazanet & R. Caloz

  10. How to validate contents ? • MAIN ISSUE: Provide an exhaustive content avoiding redundancies => integration of modules’ content ! • Which notion in which module? • Choice of the module • Choice of the level: Basic / intermediate / advanced EPFL – LaSIG lab. C. Plazanet & R. Caloz

  11. Which notion in which module? Georeference Relief modeling DTM, TIN Network modeling Metadata Conceptual modeling EPFL – LaSIG lab. C. Plazanet & R. Caloz DC SM DM SY PR AN

  12. Which notion in which module? The choice depends on : The logic of the modules (structural line) B-SM follows the process of GIS modeling from perception and abstraction to DB modeling, through fundamental models: vector/raster (without considering a particular application) I-SM considers modeling according to proprieties and objectives: analysis, generalization, cartographic presentation … The duration of the modules (number of credits) The complexity of notions The importance of the notion in the curriculum EPFL – LaSIG lab. C. Plazanet & R. Caloz

  13. Spatial modeling modules outflow EPFL – LaSIG lab. C. Plazanet & R. Caloz

  14. Links between SM and AN modules NETWORK MODELING + Level of abstraction e.g. Road network INTERMEDIATE e.g. Route maps Internal structuring properties. Model properties Abstraction level Visual apprehension of reality BASIC e.g. Road polylines e.g Selection of roads longer than 1000 m SPATIAL MODELING SPATIAL ANALYSIS EPFL – LaSIG lab. C. Plazanet & R. Caloz -

  15. Links between SM and AN modules RELIEF MODELING + Level of abstraction INTERMEDIATE Internal structuring properties. Model properties Advanced geomorphometry e.g topo. objects extraction on TIN… TIN, Morphological properties… Abstraction level Visual apprehension of reality BASIC Introduction to DTM Terrain analysis on DTM SPATIAL MODELING SPATIAL ANALYSIS EPFL – LaSIG lab. C. Plazanet & R. Caloz -

  16. Conclusions and open questions for the schools • First testings in Spring 2003 • Where we are: • Variable units duration according to learning objects • Fix strcuture and order of modules • Fix order of units for each module • In each author’s natural langage • We have to go on developping content while there are still open questions… • … on integration issues in schools !!! • Complete adoption OR Keep existing GI curriculum by re-organizing GITTA units ? • Complete e-learning OR Mix traditional & e-learn ? EPFL – LaSIG lab. C. Plazanet & R. Caloz

  17. Extra slides in case of tech. Questions…

  18. Content of a unit E-C.L.A.S.S. : Guide to On-Line course development Dr Gerson Johnson County Community College • E = Explain • C = Clarify • L = Look • A = Act • S = Share • S = Self Evaluation EPFL – LaSIG lab. C. Plazanet & R. Caloz

  19. XML structuration of contents => Content and presentation separated ! Structuration XML: content and metadatas Publication HTML, PDF, WAP… Redaction of content Unit1meta.xml Sources: Docs Word, images, animations … XML XSL Formulaire E-C.L.A.S.S. EPFL – LaSIG lab. C. Plazanet & R. Caloz Unit1.xml • DTD • based on L.M.M.L. (Learning Material Markup Language) • and E-C.L.A.S.S.
