AI中文摘要：
除感知外，推理在遥感的高级解释、推断和决策中至关重要。大语言模型的进展使工具增强型智能体得以利用外部工具执行复杂分析任务。但现有遥感研究主要集中在感知任务，认知地理空间推理探索不足。为此引入TerraLogic基准，包含545个场景驱动、层次感知任务，跨越多种图像类型，推动评估向认知级地理空间分析发展。还提出HieraPlan工具增强智能体，能组织工具包成功能层次并进行容错推理。实验表明当前方法在分层地理空间推理上有困难，而HieraPlan提供了强大基线。数据集和智能体代码可公开获取。
英文摘要：
Beyond perception, reasoning is essential in remote sensing for advanced interpretation, inference, and decision-making. Recent advances in large language models (LLMs) have enabled tool-augmented agents that leverage external tools to perform complex analytical tasks. However, existing studies in remote sensing primarily focus on perception-oriented tasks, leaving cognitive geospatial reasoning largely underexplored. To address this gap, we introduce TerraLogic, a benchmark for geospatial reasoning. TerraLogic comprises 545 scenario-driven, hierarchy-aware tasks, such as hazard vulnerability assessment, urban heat island analysis, and forest fragmentation dynamics, spanning optical, Synthetic Aperture Radar (SAR), and infrared (IR) imagery. It advances evaluation beyond recognition and monitoring toward cognitive-level geospatial analysis. To facilitate evaluation on TerraLogic, we further propose HieraPlan, a tool-augmented agent that organizes toolkits into functional hierarchies and performs fault-tolerant reasoning. HieraPlan enables structured abstraction, robust recovery from tool failures, and stable long-horizon planning. Extensive experiments demonstrate that current approaches struggle with hierarchical geospatial reasoning, while HieraPlan provides a strong baseline with improved reasoning, cross-modal generalization, and error handling. The dataset and agent code are publicly available at https://github.com/Ireliya/TerraLogic.
