摘要
通过实际应用,揭示了3S技术在土地开发整理中的应用方法和前景,结果表明:RS为土地开发整理提供了精确的土地利用现状数据和直观的整理范围;GIS可以快速准确地为土地开发整理提供各种地类的净面积以便分析研究,同时可以快速高效地制作成果图件和科学的规划设计;GPS-RTK可以准确地计算出平田整地的土方量和沟渠断面的设计精度。并提出土地开发整理三维规划的前景。
The paper revealed the application methods and prospects of 3S technology in the land development through the actual work and practices. The results showed that RS provided accurate data of land utilization present situation and the intuitive consolidation range for the land development, GIS could provide a variety of all kinds of land type＇s net area of land development quickly and accurately for analysis, produce maps results and scientific planning and design quickly and efficiently, GPS-RTK could accurately calculate the earth volume of flat field soil preparation and the design accuracy of field ditches cross-section. The prospect of three-dimensional planning in land development was also put forward.
