Geo for the Agentic Era: Highlights from #SDSC25 London showcased a new era of GIS where AI agents and open data formats are transforming geospatial analysis, making spatial intelligence accessible to anyone. Leaders gathered to share their takes on challenges and opportunities in this reinvented field. Key highlights include the introduction of CARTO AI Agents, enabling natural language interaction with data, and the importance of open table formats like GeoParquet and Apache Iceberg for standardized storage and multi-engine access. The conference also emphasized the need for common frameworks to enable seamless collaboration across industries and highlighted the role of agentic AI in amplifying geospatial expertise rather than replacing it.
