Call for Participation Joint ISPRS/EARSeL Workshop on Fusion of Sensor Data, Knowledge Sources and Algorithms for Extraction and Classification of Topographic Objects Valladolid, Spain 3 June to 4 June 1999 For detailed information about this workshop please visit the web at: http://www-earsel.cma.fr/earsel_events . THE WORKSHOP This two-day workshop will directly follow the 19th EARSeL Symposium in Valladolid, May 31 to June 2. The workshop will deal with both airborne and spaceborne sensor data for the detection, reconstruction and classification of topographic, urban and other objects. Later tasks are very difficult to automate. To reduce this difficulty, combinations of sensors, data, processing methods and a priori knowledge sources have increasingly been used. Examples include: - integration of sensors (e.g. simultaneous use of various optical sensors and GPS/INS) - use of multispectral, multitemporal, multiresolution, multisensor and multiple polarisation data - use of multiple algorithms on the same data and combination of the partial results - use of a priori knowledge (e.g. existing digital maps or other spatial information databases, models, rules etc.) to constrain the search space or verify the results The workshop will present related research work and serve as a forum for discussion on various still unsolved problems. The emphasis will be on the development of methods and algorithms for data processing in various application fields and less on data acquisition. 30 papers from 11 countries will be presented in single track sessions (seven Technical Sessions and one Interactive Session). Most technical sessions have only 3 papers, thus allowing plenty of time for intensive discussions and preserving the workshop character of the meeting. The proceedings of the workshop will be published in the series of the International Archives of Photogrammetry and Remote Sensing and will be available on-site.
