About
The 2nd ACM SIGSPATIAL International Workshop on Geospatial Anomaly Detection (GeoAnomalies'25) 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.

Call For Papers (PDF version)
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. 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. As GeoAnomalies papers appear in the ACM SIGSPATIAL proceedings we follow the same submission process. Following the main-conference, we also allow full papers to have a two-page appendix beyond the ten pages limit.
Example topics include, but not limited to:
| Theoretical Foundations of Geospatial Anomaly Detection | Machine Learning for Geospatial Anomaly Detection |
| Statistical Models for Geospatial Anomaly Detection | Complex Network Analysis |
| Spatio-Temporal Modeling | Case Studies and Real-world Applications for Anomaly Detection on Spatial Data |
| Benchmarking and Evaluation |
Paper Format
Accepted GeoAnomalies'25 papers will appear in the ACM SIGSPATIAL'25 Proceedings. Therefore, we follow the same formatting requirements as ACM SIGSPATIAL'25 which can be found [Here]
Manuscripts should be submitted in PDF format and formatted using the ACM camera-ready templates available at [Here]
SIGSPATIAL uses the Conference Proceedings Primary Article template with two-column format. Alterations to the template, especially to gain more space, will be grounds for administrative rejection without further technical review. 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.
