摘要
等值线是进行地理要素空间特征分析的强大工具,可用以从总体上把握研究对象的空间变化特征,是一种形和数的统一.应用陆地卫星5、4、3三个波段合成的遥感图像作为数据源,通过对昂拉仁错湖泊湖底地形等高线的绘制,真实再现了昂拉仁错湖泊水体深度变化的情况.
The isoline is a strong tool that is used to analyse the space characteristic of geographical key element. And the changing of the space characteristic can be held on the whole. So, it is the unity of shape and numeral. In this paper, the land satellite 5,4,3＇s three images are used as the data source,and the Anglarencuo Lake isoline chat is drawn. The circumstances about the Anglarencuo Lake depth is reflected in the chart.
