Keynote by Thomas Blaschke, University of Salzburg

The need for an OBIA workshop:

High spatial resolution remotely sensed images have become commercially available and increasingly used in various aspects of environmental monitoring and management. Analysts face challenges dealing with the detail provided by the imagery. New classifiers that make inferences based not only on spectral properties, but also on information such as object shape, texture, spatial relationship as well as human knowledge are proving to be useful in this high spatial resolution world.  These object-based classifiers are new, and proving to be useful in many applications. The object-based image analysis research field is rapidly developing, the GIIF will be hosting a symposium and workshop for OBIA practitioners from academia, government and industry where we will discuss the latest developments in programming and application, and work through some of the more thorny problems facing scientists using these tools.

The objectives were to:

• Build a community of OBIA practitioners from academia, government and industry,
• Promote knowledge exchange among scientists,
• Develop new tools for object-based image analysis,
• Evaluate open source and freeware image segmentation and classification, and
• Develop plans and outlines for a Special Issue on OBIA.

On Friday afternoon, at the conclusion of the symposium, the group discussed outstanding issues and future directions. View notes on this discussion here: Notes as Word Doc, Notes as PDF.
