基于3S技术精准化调查在第三次土地调查中的应用

Application of Precision Survey Based on 3S Technology in the Third Land Survey

第三次全国土地调查主要目标之一是掌握准确的全国土地利用现状和土地资源变化情况,实现成果信息化管理与共享。3S一体化技术具有准确、快速、及时、大范围的优势以及强大的空间信息采集、编辑、处理、分析和管理能力,通过3S集成技术能迅速获取高精度数据,实现三调的精准化测量。通过三调试点区域3S技术的综合应用,建立及时精准的调查技术体系,提供准确的数据资料,满足第三次土地调查工作及国土管理工作的需求。

One of the main objectives of the third national land survey is to grasp the accurate state of the land use and the change of land resources in order to realize the information management and sharing of the results. 3S integration technology has the advantages of accurate, rapid, timely and wide range, and powerful ability to collect, edit, process, analyze and manage space information. Through 3S integrated technology, high precision data can be obtained quickly, and accurate measurement of three tones can be realized. Through the comprehensive application of the 3S technology in the three pilot regions, a timely and accurate survey technology system is established, and accurate data are provided to meet the needs of the third land survey and land management.
