The following represented key conference topics:
1. Image segmentation
- New segmentation methods
- Tree crown delineation from optical and/or lidar data
- Delineation of man-made features (roads, buildings, urban features, etc)
- Evaluation and comparison of segmentation methods
2. Geographic-object based classification and modeling
- New classification methods
- New object-based dynamic modeling approaches (i.e., cellular automata, etc)
- Operationalization of relational features between objects
- Comparative studies of object-based and pixel-based methods
3. Methodological issues and challenges
- Requirements for object-based accuracy assessment
- Creating a standard GEOBIA ontology
- Integration and processing of very large tiled datasets
- Multi-scale and multi-temporal representations
- 3D (LiDAR, DEMs, DCMs, etc)
- Integration into GIS
- Visualization
4. Applications
- Semi-automated map updating
- Monitoring (Landuse/Landcover [LULC], ecological processes, forest practices, ice, urban, etc)
- Disaster management (floods, forest fires, earthquakes, droughts, oil spills, etc)
- Automated feature detection for specific targets (urban, topography, individual tree ID, military/security applications, etc)
