本文简要介绍了浙江省洪涝灾害遥感监测技术流程及其初步应用。研究表明，应用ＮＯＡＡ—ＡＶＨＲＲ数据，通过计算机处理和综合地学分析，是可以监测大范围的洪涝灾害的，并可准确地圈定洪涝范围和区分受涝程度，获得洪涝灾害面积，从而达到快速、动态、客观地监测洪涝灾情的目的，及时地向领导决策部门提供灾情影像图、数字化图和灾情分析报告，为指挥抗灾、组织生产自救提供可靠依据。 This article briefly introduces the remote sensing monitoring technology process of flood and waterlogging in Zhejiang Province and its preliminary application. The research shows that applying NOAA-AVHRR data can monitor a wide range of flood disasters through computer processing and comprehensive geoscientific analysis. It can accurately delineate the scope of floods and distinguish floods and obtain the area of ​​floods and floods so as to achieve rapid and dynamic Objectively monitor the purpose of floods and provide the decision-making departments in charge with the disaster images, digital maps and disaster analysis reports in a timely manner so as to provide a credible basis for directing disaster-resistance and organizing self-help in production.
