The Symposium, as one of the most important events of ISPRS Technical Commission IV, is to provide an inter-disciplinary forum for scientists, researchers and practitioners in the field of “Geo-spatial databases and location based services”. The participants of the Symposium will present the latest developments and applications, discuss cutting-edge technologies, exchange research ideas, and promote international collaboration. It should be mentioned that this ISPRS TC IV Symposium is just one week ahead of the TC VI Symposium that will be held also in China (Wuhan) during 23-25 May 2014. For those interested in both symposiums can combine a visit to China for both events.
