The Joint International Conference on Geospatial Theory, Processing, Modelling and Applications is hosted by the Canadian Institute of Geomatics (CIG) and co-organized by the International Society for Photogrammetry and Remote Sensing (ISPRS) Technical Commission II on Theory and Concepts of Spatial Information Science, International Geographical Union (IGU) Commission on Geographical Information Science and Commission on Modelling Geographical Systems. With a theme on Building Connections in GISciences for Future, the conference intends to present and disseminate the research, development and the innovative applications of geographical information theory and technologies in broad areas, as well as other interested areas by the participating organizations. This conference joins the following symposia together: 2014 ISPRS Technical Commission II Midterm Symposium 16th IGU Spatial Data Handling Symposium ISPRS Technical Commission II Midterm Symposium is held every four years in between two consecutive ISPRS Congresses. The symposium aims to bring together scholars and professionals from the international community of geospatial information sciences and engineering to present latest research achievements and technological developments. The topics of the symposium address the focuses outlined by the Commission, stated on its website: http://www2.isprs.org/commissions/comm2.html. The International Symposium on Spatial Data Handling (SDH) is the biennial international research forum for Geospatial Information Science, co-organized by the IGU Commission on Geographic Information Science and the IGU Commission on Modelling Geographical Systems. It commenced in 1984, in Zurich, Switzerland and has since been held biennially in Seattle, USA; Sydney, Australia; Zurich, Switzerland; Charleston, USA; Edinburgh, UK; Delft, The Netherlands; Vancouver, Canada; Beijing, China; Ottawa, Canada; Leicester, UK; Vienna, Austria; Montpellier, France; and Hong Kong, China. The International Symposium on Spatial Data Handling has become a major resource for recent advances in GIS research and is regarded as a premier international research forum for GIS.
