The SIGSPATIAL Special (Volume 15, Number 1, July 2025) marks an important return after a two-year publication pause. This issue brings the community back together with a comprehensive set of workshop reports from ACM SIGSPATIAL 2024, a message from the editors, and announcements about new initiatives for ACM SIGSPATIAL 2025. The newsletter highlights the vibrant growth of the spatial computing community across GeoAI, geospatial simulation, spatial epidemiology, sustainable mobility, anomaly detection, and more.

Closing Thoughts

This July 2025 issue of The SIGSPATIAL Special captures a broad and energetic snapshot of the spatial computing field—from AI-driven geographic discovery and urban modeling to epidemiology, simulation, and new conference initiatives. As the community moves toward ACM SIGSPATIAL 2025 in Minneapolis, the newsletter provides both a retrospective on workshop achievements and a look ahead at exciting new tracks and opportunities.
