This research introduces CEAE, a hierarchical agentic framework that translates natural language instructions into precise, spatially consistent edits of urban geospatial plans. By decomposing complex renewal tasks into geometric intents and employing a self-reflective validation loop, the system significantly improves execution validity and robustness over existing baselines. The work represents a notable advancement in applying autonomous agent architectures to solve constrained, real-world geometry problems within AI-driven planning workflows.

City Editing: Hierarchical Agentic Execution for Dependency-Aware Urban Geospatial Modification

arXiv:2602.19326v3 Announce Type: replace-cross Abstract: Urban renewal requires incremental modifications to existing geospatial plans, yet manually updating complex layouts under spatial constraints is labor-intensive and error-prone. To tackle this, we propose CEAE, a hierarchical agentic framework that formulates urban renewal as machine-executable GeoJSON editing from natural-language instructions. CEAE decomposes instructions into hierarchical geometric intents, executing edits from coarse to fine while preserving spatial consistency through a self-reflective execution-validation loop. Experimental results show that CEAE outperforms baselines in execution validity, robustness, and geometric accuracy.
