土地资源调查中遥感影像分类与识别技术的应用探讨

Research on application of remote sensing image classification and identification technology in land resources survey

我国有着较为丰富的土地资源,土地资源的调查工作对社会发展有重要意义。然而,相关调查部门还在使用传统且老旧的技术和设备,会对调查结果产生较大影响,引发各种问题和风险。土地资源调查部门在开展调查工作时要充分应用遥感影像分类与识别技术,确保调查工作正常开展、调查结果真实有效。基于此,阐述了遥感影像在土地资源调查中的作用,介绍了遥感影像技术、影像分类与识别的原理、监督分类,分析了遥感影像分类与识别工作流程,以供参考。

China has relatively rich land resources,and the investigation of land resources is of great significance to social development.However,the relevant investigation departments are still using traditional and old technology and equipment,which will have a great impact on the investigation results and cause various problems and risks.The land resources survey department should fully apply the remote sensing image classification and identification technology when carrying out the survey work to ensure that the survey work is carried out normally and the survey results are true and effective.Based on this,the role of remote sensing image in land resource survey is expounded,the remote sensing image technology,the principle of image classification and identification and supervision classification are introduced,and the working process of remote sensing image classification and identification is analyzed for reference.
