What is solved ?

• Topological data structures
• LBS Where is next restaurant ?
• Industry has taken over
• Earth Viewers
• Industry has taken over

3
What has failed ?

• Quality / uncertainty handling
• Beyond Epsilon-band ??
• No solutions for
• Mix of nominal and geometric quality measures
• Propagation of quality in analysis processes
• Communication / visualization of quality
  parameters
• Surprisingly (yet) low success
• Use of AI-techniques
• E.g. ML for knowledge acquisition

4
What is missing ?

• Geosensor networks
• Where are the real applications ?
• Methods for structure recognition in spatial data
  sets
• Detect higher level structures in geodata
• Use of techniques from image analysis, e.g.
• Implicit shape models
• Symmetry detection
• Structural learning

5
What is next ? Hot Topics

• Semantics
• Temporal data moving objects
• Spatial data interpretation / data mining
• Fusion of geodata, especially image and vector,
  but also data from different ontologies
• Multiscale issues
• Ubiquitous computing
• Neo-Geography
• Geosensor networks
• Applications
• Traffic
• epidemiology

Hot Topics

• Geosensor networks
• User-generated geospatial content
• New representations
• integrate low and high level data (e.g. raw image
  data and interpreted GIS-data)
• On-the-fly interpretation and integration
  facilities
• Quality management
• Storage concepts, aggregation concepts
