The complexity, diversity, and rapid growth of geospatial data have increased significantly over recent decades and are driving discoveries in a large number of application and science domains. Access to and interaction with geospatial big data collected from numerous sources are increasingly fundamental to explore natural, human and social systems at unprecedented scales and provide tremendous opportunities to gain dynamic insight into complex phenomena through big compute (e.g. cloud and high-performance computing) and CyberGIS approaches. CyberGIS (geographic information science and systems (GIS) based on advanced cyberinfrastructure) represents new-generation GIS in the era of big data, and has emerged during the past several years as a vibrant interdisciplinary field. The primary goal of this workshop is to bring together thought leaders and cutting-edge researchers from pertinent multidisciplinary communities to explore the frontiers of geospatial data science.
