Working group activities

• Goal
• Integrate existing algorithms in an open software
  environment
• Visited ESRI in Rotterdam
• Discussed the proposed architecture
• Installed the ESRI environment
• Missing
• Realizing the proposed architecture
• Applying it to actual data (TOP10 -gt TOP50)

Proposed architecture

Research visit at IGN

• Goal
• Get experience with 1spatials Clarity
• Apply Clarity on Top10NL data
• Discussing the idea of Web Generalization Service
• Have been introduced to the generalization group
  at COGIT
• Joined the EuroSDR meeting

Publications

• Foerster, Stoter, Koebben, van Oosterom A Common
  Approach to Simplification of Geodata for Mobile
  Applications, AGILE 2007.
• Foerster, Stoter Towards a formal classification
  of generalization operators, ICC 2007 (to be
  held).

Outlook

• Requirements analysis towards automated
  generalization of topographic data
• Model generalization
• Implementing chains within the WG
• Cartographic generalization
• Implementing basic constraints for cartographic
  generalization

10
Outlook (contd.)

• Formalization of generalization operators
• Linking the procedural model with the operator
  hierarchy
• Experience with generalization
• Application for the formalization
• Proof for the suggested hierarchy
