GeoAgentBench: A Dynamic Execution Benchmark for Tool-Augmented Agents in Spatial Analysis

2026-04-16 · Source: cs.AI updates on arXiv.org · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Robotics & Autonomous Systems, Data Science & Analytics · Depth: Expert, extended

Summary

GeoAgentBench (GABench) is a new dynamic and interactive evaluation benchmark designed for tool-augmented Large Language Model (LLM) agents in Geographic Information Systems (GIS). It addresses limitations of existing benchmarks that rely on static text or code matching by providing a realistic execution sandbox with 117 atomic GIS tools and 53 spatial analysis tasks across 6 core GIS domains. GABench introduces the Parameter Execution Accuracy (PEA) metric, which uses a "Last-Attempt Alignment" strategy to quantify implicit parameter inference, and a Vision-Language Model (VLM)-based verification for data-spatial accuracy and cartographic style. The benchmark also proposes a novel "Plan-and-React" agent architecture, which decouples global orchestration from step-wise reactive execution. Experiments with seven LLMs demonstrate that Plan-and-React significantly outperforms traditional frameworks, achieving optimal balance in logical rigor and execution robustness for multi-step reasoning and error recovery.

Key takeaway

For AI Engineers developing autonomous GeoAI systems, GABench highlights the necessity of dynamic, interactive evaluation. You should adopt the "Plan-and-React" architecture to balance global planning with local error recovery, significantly improving agent performance in complex, multi-step GIS workflows. Focus on robust parameter inference and leverage multimodal verification for accurate and aesthetically correct spatial outputs, moving beyond static code-matching for real-world reliability.
