航空遥感应用于广州市土地利用调查与制图

Application of Aerial Remote Sensing Techniques to Land Use Inventory and Mapping of Guangzhou

采用几种判读方法对不同片种(彩色片、彩色红外片、黑白片)进行象片判读。用精密立体测图仪转绘土地利用类型要素和地理基础要素,编制成广州市土地利用图。通过面积量测,获得各种土地利用类型的面积数据;对土地利用现状进行了分析,为城市的规划、建设和管理提供可靠资料与建设性意见。

Aerial photograph interpretation is carried out by using different kinds of photographs (color, color infrared, white and black) and several interpretation methods. With a precise stereoploter (which: conduces raising mapping accuracy and speed), a land use map of Guangzhou is compiled. Through measure of area various data on the area of land use type are obtained, which provids reliable materials for planning, construction and management of the city. Finally, an analysis of the present condition of land use is made, and some contructive sug- gestions for rational land use in futhure are presented as well, and makes con- structive suggestions.
