遥感影像分辨率与地图比例尺的关系及应用浅析

Relation between Remote Sensing Image Resolution and Map Scale and Its Application

多种分辨率、多尺度等概念,是描述遥感影像、数字制图、数字摄影测量的重要技术指标,这些概念与地图学上表示的比例尺有一定的异同点。本文从这些概念的定义、分类及相互间的关系出发,结合黄河中游土地利用现状、水土保持措施分布情况的遥感监测影像分析资料,提出对影像空间分辨率应用的建议意见,对从事遥感制图工作者在遥感技术应用和数字制图方面有较好的参考作用。

Multi-resolution,multi-scale are important technical indices describing remote sensing image,digital mapping,and digital photogrammetry,which have differences and similarities with map scale.The paper discussed these definitions,catagories and their relations and then put forth suggestions for the application of image spatial resolution,basing on the data analysis of remote sensing image of current land use of upper reaches of the Yellow River and soil and water conservation measures layout,in order to provide reference for people engaged in remote sensing technology and digital mapping.
