    基于大语言模型的遥感信息产品智能分析系统

    An intelligent analysis system for remote sensing information products based on large language models

    • 摘要: 随着遥感科学技术的迅速发展,遥感信息产品数据呈现出海量化与多样化的特征。现有平台虽具备基础数据服务和信息处理能力,但在自动化知识提取和专业化问答服务方面仍存在局限,难以智能解析用户需求并动态生成适应性的分析流程。针对这一问题,该文提出并构建了一个基于大语言模型的遥感信息智能分析框架,并以地表覆盖制图为实验场景进行验证。该框架运用自然语言解析和提示工程技术,自动完成时空映射、核心变量构建和指标生成,并调用开放数据立方体进行高效的数据管理与计算。实验结果表明,该系统在综合遥感数据分析能力上超越了单纯依赖生成式预训练变换器(generative pre-trained Transformer, GPT)生成的结果,显著提升了知识服务的准确性和专业性,有望推动遥感信息产品的智能知识服务发展。

       

      Abstract: With the rapid development of remote sensing-related science and technology, remote sensing information products are characterized by massive volume and great diversity. Despite possessing basic data services and information processing capabilities, the existing platforms still face limitations in automated knowledge extraction and specialized question-answering services. Consequently, they fail to intelligently parse user needs and dynamically generate adaptive analytical workflows. To address these limitations, this study proposed and preliminarily developed an intelligent analysis framework for remote sensing information products based on large language models (LLMs), with land cover mapping serving as an experimental scenario for validation. Using natural language parsing and prompt engineering techniques, the framework can achieve autonomous spatiotemporal mapping, core variable construction, and indicator generation. Moreover, it enables efficient data management and computation using the Open Data Cube (ODC). Experimental results show that this intelligent system outperformed the solely GPT-based approach in comprehensive capability for remote sensing data analysis, significantly enhancing the accuracy and specialization of knowledge services. It has the potential to advance intelligent knowledge services for remote sensing information products.
