The proliferation of geospatial data has accelerated due to advances in Earth Observation (EO) technologies, the widespread deployment of Internet of Things (IoT) sensors, the rise of open science initiatives, and the increasing availability of cloud-native and AI-driven geospatial platforms. This data is now highly heterogeneous in format, modality, resolution, and temporal scale, and is being generated at unprecedented speed and volume. These trends introduce significant challenges—and opportunities—in how to efficiently search, integrate, and mine massive, multimodal geospatial datasets to reveal meaningful patterns and support informed decision-making.

Example topics include but are not limited to:

• Search and Retrieval using LLMs, VLMs and World Model
• Geospatial Reasoning for Effective Search and Retrieval
• Spatial Representation Learning for Search and Retrieval
• Spatial Pattern Matching
• Geospatial Knowledge Graphs for Search
• Multimedia Information Retrieval
• Neural Search in Spatio-temporal Data
• Search in Large Spatio-temporal Data Cubes
• Searching Geospatial Objects - Vector Geometry, 3D Point Clouds, Spatial Trajectories, Positioning, Localization and Navigation
• Metadata design and cataloguing of Machine Learning Models
• Design of Data and Model Relational Structures
• Keyword-Search in Spatial Data
• Spatial Index Structures for Search
• Scalable Search Interfaces, Frameworks and Implementations
• Data Representations and Containers facilitating content-based retrieval

GeoSearch '25 Workshop Proceedings https://dl.acm.org/doi/proceedings/10.1145/3764920

The GeoSearch 2026 is a half-day workshop in the 34th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems (ACM SIGSPATIAL 2026), which consists of keynotes and individual paper presentations. Two submission format will be included in this workshop:

• Full research paper: 6-8 pages
• Short research paper or demo paper: 4 pages

Full research papers should present mature research on a specific problem or topic in the context of geospatial search. We also welcome short research articles or industry demonstrations of existing or developing methods, toolkits, and best practices for AI applications in the geospatial domain.

If you already have a SIGSPATIAL 4-page paper, you are welcome to submit an extended version, for example, by submitting the original full-length version that was previously shortened for the 4-page format. Authors must disclose the earlier paper, cite it properly, and clearly describe the new contributions in the extended version relative to the original paper.

Manuscripts should be submitted in PDF format and formatted using the ACM camera-ready templates available at http://www.acm.org/publications/proceedings-template. All submitted papers will be peer reviewed to ensure the quality and the clarity of the presented research work. Submissions will be single-blind — i.e., the names affiliations of the authors should be listed in the submitted version.

For each accepted paper, at least one author must register for the ACM SIGSPATIAL conference, attend the workshop, and present the paper during the workshop.
