Proceedings of the 30th International Conference on Advances in Geographic Information Systems

The conference started as a series of workshops and symposia back in 1993 with the aim of promoting interdisciplinary discussions among researchers, developers, users, and practitioners and fostering research in all aspects of geographic information systems, especially in relation to novel systems based on geospatial data and knowledge. It continues to provide a forum for original research contributions covering all conceptual, design and implementation aspects of geospatial data ranging from applications, user interfaces and visualization, to data storage, query processing, indexing, machine learning and data mining. The conference is the premier annual event of the ACM Special Interest Group on Spatial Information (ACM SIGSPATIAL).
