Artificial Intelligence and Uncertainty Modeling in Spatial Analysis

Our Mission

We are rapidly entering into an unprecedented “geospatial data governance era”. Our working group argues that we must seize the opportunity to intelligently collect and retrieve these diverse geospatial data and use spatial analysis, spatial statistics and artificial intelligence (AI) methodologies like deep learning to address pressing environmental and socioeconomic challenges requiring solutions at local to global scales. A particular issue concerns the uncertainty and quality of these data. The data are produced either by official organizations or volunteer citizens (crowdsourcing). A great diversity of data is available, including data produced via space-based, airborne-based, ground-based, and human-based sources. Smart fusion and assessment of data collected from space- and air-borne sensors, geosensors, biosensors, and human sensors, including volunteers, social networks, and crowdsourcing, is challenging, which represents technical barriers to addressing the pressing problems. While spatial data are arguably “big spatial data”, like in remote sensing images, the current context is especially critical, as smart collection, integration, and analysis of big geospatial data are increasingly impacted by the seven V’s: volume, velocity, veracity, validity, value, variability, and variety. Intelligent decision made on the basis of big geospatial data are therefore best to be aware of the uncertainties inherent within these data. The vast availability of geospatial data of an ever increasing fine spatial and temporal resolution has resulted in big data volumes, and challenged the GIScience communities to develop smart artificial intelligence (AI) algorithms that are suitable for addressing numerous emerging global societal challenges. These include challenges in the areas of climate change, water, and food security, energy, health, biodiversity, and social well-being. Fortunately, open-source technologies can contribute to facilitate this goal by developing and sharing transparent, out-of-the-software-box, open science tools available for everyone. Furthermore, the progress in AI, semantics, and spatial as well as spatio-temporal statistics provides novel opportunities that allow for the smart leveraging of massive spatial data beyond the existing approaches to explore and assess new information, pattern, and knowledge. In our working group we aim to further develop intelligent methodologies e.g. for data fusion and integration. In this way, we will be optimizing reliable spatially referenced information extraction and to model and assess their contributions to informed decision-making that addresses environmental and socioeconomic challenges facing society in the 21st century.
