GeoAnomalies'26 @ ACM SIGSPATIAL

Call for Papers

Scope & Research Topics

The 3rd ACM SIGSPATIAL International Workshop on Geospatial Anomaly Detection (GeoAnomalies’26) is dedicated to assembling leading researchers and esteemed industry experts to examine the latest advancements, formidable challenges, and compelling applications within the crucial domain of anomaly detection for spatial, geospatial, and spatiotemporal data. This workshop is passionately designed to cultivate profound collaboration and extensive knowledge sharing among participants from a comprehensive array of research fields—including machine learning, time series analysis, statistics, remote sensing, geospatial analysis, and trajectory analysis. Download the printable Call for Papers (PDF).
We accept papers addressing issues related to, but not limited to, the following topics:

Theoretical Foundations of Geospatial Anomaly Detection

Mathematical Models for Anomaly Detection
Information Theory for Anomaly Detection
Uncertainty Modeling

Machine Learning for Geospatial Anomaly Detection

Supervised, Unsupervised & Semi-supervised Techniques
Generative, Discriminative Models

Statistical Models for Geospatial Anomaly Detection

Parametric and Non-Parametric Methods
Hypothesis testing for Anomaly Detection

Case Studies and Real-world Applications for Anomaly Detection

Urban Planning and Traffic Anomaly Detection
Disaster Response & Public Safety
Human Behavior Anomaly Detection

Benchmarking and Evaluation

Datasets/Metrics for Geospatial Anomaly Detection
Comparative Studies

Author Guidelines

Formatting

The workshop seeks high-quality full (8-10 pages) and short (4 pages) papers that have not been published in other academic outlets and are not concurrently under peer review.
Accepted GeoAnomalies’26 papers will appear in the SIGSPATIAL’26 Proceedings. Therefore, we follow the same formatting requirements as SIGSPATIAL'26 which can be found on the Submission Information.

Review Process

Submissions to ACM SIGSPATIAL are single-blind. – i.e., the names and affiliations of the authors should be listed in the submitted version. The author list is considered to be final after the submission deadline and no changes to the author list are allowed for accepted papers.
Once accepted, at least one author is required to register for the workshop and the ACM SIGSPATIAL conference, as well as attend the workshop to present the accepted work which will then appear in the ACM Digital Library.
