航空遥感应用于广州市土地资源调查与制图

Application of Remote Sensing Techniques to Inventory and Mapping of Land Resouces of Guangzhou

根据广州市航空遥感综合调查计划,通过黑白航片(1∶15000)和彩色红外象片(1∶22000)的判读,编制了两幅广州土地资源图(1∶25000及1∶50000)。土地资源分为城市建设用地(A)及城郊田园化用地(B)两大类。遥感容易获得各种同步信息;彩色红外片有利于土地类型分析;多阶段摄影有利于动态分析。

According to the plan of the aerial remote sensing for comprehensive survey of Guangzhou city, two maps of land resouces (1:25000 and 1:50000) have been compiled through interpretation of black and white (1:15000) and color infrared aerial photographic imagery and analysis of the land-types. The land resouces are divided into two groups: (A) land for urban development, and (B) suburban garden land. The advantages of remote sensing as a method of map compilation are: the use of remote sensing is easy to acquire manifold synchronous informa- tion; color infrared aerial photographic imageries contribute to land types anal- ysis; and multistage aerial photography is convenient to dynamic image analysis.
