本文介绍一种利用高分辨率遥感数据与数学模型绘制针叶林的新方法,适于处理空间影像数据。结果绘制出了伊尔库次克北部Ust-Ilimsk地区的针叶林图。本文认为对景观判读绘制成图的GIS技术需要包括信息调查程序、地图综合数据和以目标为导向的景观图与知识的阐释。应用新方法生产预测林型动态变化的分布图,此方法使用数学分析模型在研究区数字地图上勾绘地表组成,并根据直方图勾绘典型的地表组成。
This paper presents a new method for mapping coniferous forest using high resolution remote sensing data and mathematical models, which is suitable for processing spatial image data. The results plot the coniferous forest in the Ust-Ilimsk area of northern Irkutsk. This paper argues that the GIS technology of landscape mapping needs to include information survey procedures, integrated map data and goal-oriented landscape diagrams and knowledge interpretation. The new method is used to produce the distribution map of predicting the forest dynamic change. This method uses the mathematical analysis model to map the surface composition on the digital map of the study area and draws a typical surface composition according to the histogram.
