The thirty-third edition of ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems 2025 (ACM SIGSPATIAL 2025) will be held in Minneapolis, MN, in November 2025. The conference began as a series of symposia and workshops starting in 1993 with the aim of bringing together researchers, developers, users, and practitioners in relation to novel systems based on geospatial data and knowledge, and fostering interdisciplinary discussions and research in all aspects of geospatial information systems. The conference provides a forum for original research contributions covering all conceptual, design, and implementation aspects of geospatial data ranging from applications, to data storage and query processing, to internet of spatial things and spatial AI. The conference is the premier annual event of the ACM Special Interest Group on Spatial Information (ACM SIGSPATIAL). Researchers, students, and practitioners are invited to submit original, unpublished research papers not being considered for publication in any other forum.

Submission Guidelines

This year there are two avenues for short paper contributions:(1) A paper submitted to the research track of the ACM SIGSPATIAL conference may be accepted as a short paper (see the corresponding Call For Papers).(2) A paper can be directly submitted as a Short Paper and will be reviewed by the separate Short Papers PC. This is a new mechanism this year.

Short papers have at most 4 pages (including references), prepared using the ACM two-column conference proceedings template, and will appear in the conference proceedings. They will be presented at the conference via posters and short lightning talks.

Just as for the research track of the ACM SIGSPATIAL conference, there are two types of short papers:

Short papers about theory, models, and algorithms. These papers present original research on foundational concepts, such as novel models and algorithms for spatial computing. These papers are invited, where appropriate, to include a sketch of prototype implementation and an initial evaluation that may include some aggregate results of the comparison with alternate approaches. Example: a novel algorithm for complex query processing or a novel model of spatial causal inference.

Short papers about systems. These papers describe the design, implementation, and empirical evaluation of a novel system, framework, or processing pipeline created to address a specific problem. It typically provides a detailed explanation of a real-world problem, the architecture, and functionality. Performance of the system, and an evaluation that may include comparisons with alternate systems are requested in an aggregate form. Example: a platform for spatio-temporal data analysis in real-time.
