Spatial and temporal thinking is important not just because everything happens at some places and at some time, but because knowing where and when things are happening is key to understanding how and why they happened or will happen. Spatial data science is concerned with the representation, modeling, and simulation of spatial processes, as well as with the publication, retrieval, reuse, integration, and analysis of such space- and place-centric data. It generalizes and unifies research from fields such as geographic information science/geoinformatics, geo/spatial statistics, remote sensing, environmental studies, and transportation studies, and fosters applications of methods developed in these fields in other disciplines ranging from social to biological and physical sciences.

Data-driven methods, such as machine learning models, have been attracting attention from the Geoscience community for the past several years. For instance, they have been successfully used to quantify the semantics of place types, to classify geo-tagged images, to predict traffic and air quality, to improve resolution of remotely sensed images, to recognize objects in such imagery, to predict and compare trajectories, to name but a few. Geospatial observations may be vague, uncertain, heterogeneous, dependent on other nearby observations, and multimodal; thus, spatial and temporal principles should be included in techniques such as deep neural networks. Unsurprisingly, research has shown that by doing so, we can substantially outcompete more general (non-spatial) models when applied to geo-data or applications with a spatial and temporal component.

To keep this discussion alive and help the community to exchange ideas and lessons learned about spatial and temporal aspects of Data Science, we are hosting the 3rd Spatial Data Science Symposium (SDSS 2022) as a distributed virtual meeting. The symposium aims to bring together researchers from both academia and industry to discuss experiences, insights, methodologies, and applications, taking spatial and temporal knowledge into account while addressing their domain-specific problems. The format of this symposium will be a combination of keynotes, scientific sessions, as well as paper presentations. In contrast to classical conferences, the community will decide on those sessions, and the main focus will be on interaction. Hence, we welcome submissions for both papers and sessions (see below). SDSS 2022 will be a distributed symposium in a sense that while the event as such will be online, we will host (and help others to host) individual get-togethers to jointly experience the symposium in person.

Data-driven decision making for accessible and equitable cities

The pervasiveness of cell phones, mobile applications and social media generates vast amounts of digital traces that can reveal a wide range of human behavior. From mobility patterns to social networks, these signals expose insights about human behaviors and social interactions. In this talk, I will discuss approaches that can help local governments and non-profit organizations better understand the spatial dynamics of cities and communities - offering additional insights beyond more traditional sources of information - and assisting in the design of more accessible, equitable and humane cities.

I will first give a high-level overview of the research that I lead in the Urban Computing Lab; followed by an in-depth description of two projects. The first project will present a novel approach to create cycling safety maps at large scale. These maps can be used by cycling activists and departments of transportation to understand safety perceptions as well as to identify accessibility to safe routes by different communities. In the second project, I will describe a new method to enhance the fairness of mobility-based crime prediction models by addressing crime under-reporting bias that can negatively affect minority communities. This work highlights that controlling for bias can improve both the fairness and the accuracy of mobility-based crime prediction models.

A Space-Place Framework for Human Dynamics Research in A Hybrid Physical-Virtual World: Are we ready for a quantum leap in the emerging metaverse?

We now live in a hybrid physical-virtual world enabled by modern technologies where we work, shop, and socialize with others in both physical and virtual spaces. With the emerging metaverse based on immersive virtual reality, human dynamics, which refers to all forms of human activities and interactions, are likely to undergo further transformations in the coming years. The new human dynamics will be a seamless integration of physical and virtual activities. Built on our earlier work in human dynamics research, we argue that the current discussions in spatial data science for human dynamics research are conceptually constrained by their physical and virtual silos. The new hybrid physical-virtual approach we are envisioning aims to transcend the simplistic dichotomy by integrating both space and place perspectives. This presentation also draws on basic concepts in quantum theory and earlier discussions on their potential applications in geography and GIScience to espouse a quantum turn in exploring the human dynamics in a hybrid physical-virtual world. It explores how concepts, methods, and understandings from the quantum physics and computing can be translated into addressing human dynamics research under a Space-Place (Splatial) GIScience framework.

Geoethics Spectrum


Dara Seidl
Colorado Mountain College

Ourania Kounadi
University of Vienna

This session seeks to address the variable ethical viewpoints on handling of personal geodata in different domains and topics such as police investigation, health insurance, health research, UAVs, transportation, privacy in public, trust & trustworthiness, and social justice. We will encourage an open discussion (with all participants) around scientifically driven yet subjective or controversial issues and highlightthe opportunities and risks related to personal (geo) data and their protection. The session will provide an opportunity to compare how spatial data scientists’ viewpoints on geoprivacy issues mirror or differ from other documented public opinions and practices on these issues.

This tutorial introduces a purely data-driven method under the umbrella of urban morphometrics. It presents the current state of urban morphology in the Python world, focusing predominantly on vector data capturing building footprints and street networks. The main part of the tutorial introduces momepy, a toolkit from the PySAL family allowing a complex multi-scale analysis of urban form from the perspective of measuring the spatial configuration of simple vector features.

Forget Data Analytics for Mobility – we need it for Accessibility!

Urban transport is a major contributor to human‐induced climate change and the only sector not showing any sign of successful carbon reduction. Technological solutions such as more efficient vehicles or alternative propulsion systems are not able to achieve the required massive reduction in the ever‐shrinking time frame for mobility transition or are merely shifting the problem to other sectors, especially the energy sector facing the same problem. Thus, there is a sharp necessity to change mobility behavior, as reductions that cannot be realized technologically must be compensated by sufficiency in transport – as much as really needed, as little as possible. This means that the focus should be changed from mobility (improving and optimizing getting around with transport services) to accessibility (improving and optimizing the possibility to reach essential destinations with as little motorized transport required as possible), e.g., by creating local mixed‐use centers providing most if not all functionalities of everyday live. This would reduce the need for motorized transport to non‐routine trips, which should consequently also be shared and made as efficient as possible. MORE
