摘要

本文论述了空间实验室测量相机（MC）拍摄的彩色红外立体像对在中比例尺地形制图、正射影像地图以及土地资源调查中的应用可能性

给出1:10万和1:20万比例尺的制图例证

表明平面位置和高程精度能满足1:10万比例尺地形图规范要求;1:10万比例尺影像图可以满足专题制图精度要求。应用数字图像处理技术

将二种来源（MC

MSS）的遥感数据做数字匹配

并进行信息提取、组合、增强和分类等处理

其结果与原始图像比较表明有独特的优越性

与MSS原始数据相比

图像的空间分辨率明显提高

各种类型界线更分明

可分辨类目增多;而与MC原始图像相比

其光谱特性获得改善且能保持原有的空间分辨率。土地利用类型解释精度与MSS和MC原始图像比较分别提高7—20％左右。

Abstract

This paper deals with mapping abilities of Spacelab images （MC

Metric Camera）

and its geo-applications. The 1:100000 and 1:200000 scale topographic maps and orthophotomap had been made from MC stereo-image

the results show that the high resolution MC images surely could meet the national standard at the scale of 1:100000 either for planimetric accuracy or for height-measuring

and could be used for revising map at scale of 1:50000.The digital combination of digitized MC image and Landsat MSS in both spatial resolution and spectral characteristics were improved and it has some advantages for land use surveying and other geo-applications. The ground checking shows that the interpretation accuracy of land-use types were improved from 7% to 20% comparing with original Landsat MSS and MC images.
