RS和GIS在土地利用更新调查中的应用

摘要

土地利用更新调查是保持土地利用调查成果的现势性的重要手段,传统的更新调查方法周期长、精度低且费用较高.近年来RS、GIS技术的迅速发展,为土地利用调查提供了新的调查手段.RS具有宏观性、及时性、动态性及多光谱等优点,GIS具有强大的空间分析和数据管理功能.通过对RS和GIS集成技术的分析研究,利用SPOT-5数据进行遥感解译、影像判读,采用MapGIS作为数据管理平台,详细阐述RS、GIS相结合的技术手段在土地利用更新调查中的具体应用.%The updating investigation of land use is a current important means to keep the land use survey but traditional investigation updating method requires the investigation of long period, high cost and low precision. In recent years, the rapid development of the technology of RS, GIS, for the land use survey provides new means of investigation. Based on the RS and GIS integration analysis, elaborated RS, GIS combination technology in updating investigation of land is used in specific applications.
