充分利用陆地卫星(Landsat)影象图片(以下简称卫片)视野广、信息量丰富、现时性强和精度高的优点,对专题要素进行解译和制图,是编制全国1:100万、省区1:50万自然条件和资源系列地图的有效途径。本文试就土地利用类型在卫片上的成象特点、制图分类和若干制图统一协调问题进行探讨。
In this paper,three problems how to use the landsat image for compiling a map of land use of middle and small scale were expounded. (1) The appearence of land use type on landsat image is explainable,but it exists some problems such as information hiding,regional diversity or unstability.So the image interpratation is limited. (2) The classification system should be suitable for interpretable ability of the landsat images.The land use types of "area-form" can be directly abstracted from landsat image,and then the land use types of "point and line-form" can be picked up and other relative data can be used to consult and supplement. The classification system of land use can detailed into the second class or into the third class for individual type. (3) The paper deals with some unified contents and methods in the land use mapping with remote sensing.
