摘要
本文研究了地图和林业图的图形数字化输入,数据处理和显示成图.包括设计各种林业生产所需要的地理要素及其编码,建立了一整套各地理要素数据的数字化输入格式、研制出相应的各种预处理算法,把原始数据从矢量形式转换成矩阵形式的算法以及各类图形图象数据之间的配准和拼接算法、能以不同色彩重迭显示多幅不同图象和地理要素图形.
This paper deals with the digitalized graphic input,data processing,and graphic display of forestry maps. The details include:the design of a geographic code for forestry;a set of formats for digitalized input of geographic data;some preprocessing algorithms for transfering orginal data from vector to arrav,and for piecing up and matching different images and graphic data;and the overlap display of landsat images and geographic graphs in diffent colour.
