2. 13.07.2015 2ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester outline 1.project & motivation 2.data enrichment horizontal and vertical relations application using thematic maps, examples 3.research concept work plan first approaches

3. 13.07.2015 3ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester project & motivation DEGEN: Data Enrichment for adaptive Generalisation the 2 subprojects focus on: 1. acquisition of enriched data, representation with MRDBs 2. exploitation of enriched data and algorithms project members: Robert Weibel & Dirk Burghardt (Principle Investigators) Moritz Neun & Stefan Steiniger (PhD Students) funding: Swiss NSF, 04/2004 – 03/2007

4. 13.07.2015 4ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester project & motivation application trends: - real-time mapping (web, LBS) - on-demand production supporting instruments: - data enrichment - MRDB (multiple LODs) - agents increasing importance of thematic mapping (polygons, POI)

5. 13.07.2015 5ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester data enrichment initial aim: The purpose of DEGEN is the data enrichment, the modelling of the enriched data and the exploitation of this enriched data focus on: thematic maps / GIS in a generic way integration of data enrichment and MRDB for generalisation  adaptive generalisation (Galanda & Cecconi)

6. 13.07.2015 6ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester data enrichment – terms & definitions horizontal relationships  single level of detail (LOD) only  common structural properties (e.g. neighbourhood, pattern, alignment)  hierarchic partonomic relations vertical relationships  linking of objects and/or object groups on multiple LODs  hierarchic partonomic relations

7. 13.07.2015 7ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester data enrichment – application domain thematic polygonal maps:  seamless (tessellation) or  distributed polygons on a common background important factors: attributes / semantics topology alignments (pattern) shape orientation

8. 13.07.2015 8ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester data enrichment – map examples geological map detailed: 1:10’000 - 1:50’000 overview: 1:500’000 - 1:1’000’000

9. 13.07.2015 9ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester data enrichment – map examples geological map alignment 1:500’000 1:25’000

10. 13.07.2015 10ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester data enrichment – map examples soil map broad range from 1:2’000 – 1:1’000’000 1:100’000 1:200’000

11. 13.07.2015 11ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester research concept work plan analysis using example maps (patterns, alignments …) analysis and improvement of existing spatial technologies  object model modelling and managing of the relations in a MRDB  data model automatic identification / generation of horizontal and vertical relations (pattern recognition, object matching …) exploitation for generalisation  e.g. agents, incremental updates, on-the-fly generalisation

12. 13.07.2015 12ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester research concept – first approaches map analysis: e.g. land use map

13. 13.07.2015 13ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester research concept – first approaches representing islands: hierarchical and topological relations of two LODs

14. 13.07.2015 14ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester research concept – first approaches map analysis: e.g. geological map

15. 13.07.2015 15ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester research concept – first approaches representing alignments: two parallel alignments of small polygons having the same orientation

16. 13.07.2015 16ICA Workshop on Generalisation and Multiple Representation; 20-21 August 2004 - Leicester research concept – conclusion map analysis - current questions: which relations can be used for data enrichment? (topology, neighbourhood order, orientation …) how to extract horizontal relations? (pattern recognition, alignments …) how match objects, object groups? (e.g. pattern, alignments) in different LODs for establishing vertical relations how represent these relations?  MRDB data model neighbourhood order alignment
