Object based landscape analysis (OBLA)
7th April, 2009 – 8th April, 2009
Two-day meeting of the RSPSoc Land Cover/Land Use SIG
Summary of meeting
Earth Observation imagery is a major source of information for characterising the Earth’s surface, but is conventionally analysed using pixel-based approaches that do not incorporate the concept of landscape features or real world objects. Approaches and technology that exploit landscape features to increase the accuracy and usability of EO-derived products are now becoming mainstream. These object-based methods employ spatial frameworks often aligned to the needs of scientists, policy makers and end users, but straightforward application of off-the-shelf packages is not always well-conceived. The aim of this meeting is to bring together practitioners in remote sensing, GIS and environmental science to identify best-practice in the development and application of object-based landscape analysis techniques.

The OBLA meeting has now passed. Presentation pdf downloads and photos of the event are available below. A meeting report will appear soon. The book of abstracts can be downloaded by clicking HERE.
Special Issue of the International Journal of Geographical Information Science
Following the OBLA meeting, there are plans to publish a Special Issue on this topic in IJGIS, to be edited by Paul Aplin (University of Nottingham, UK) and Geoff Smith (Specto Natura, UK). Researchers working in the field are invited to submit papers for this Special Issue. The call for submissions can be downloaded HERE .
