摘要
地理国情普查最主要的内容是地表覆盖分类与重要地理国情要素,其中地表覆盖主要基于遥感或航空影像影像进行分割、分类,解译出地表覆盖物的类型,以便从地理的角度进行统计分析。大比例尺地形图具有地表覆盖物与地理要素丰富信息的特点,本文结合生产实践探索出一套大比例尺地形图数据应用于地理国情普查的有效技术方法。
The content of geography condition survey is the main land cover classification and important geographical situation elements,the surface cover is mainly based on the remote sensing or aerial image image segmentation,classification,interpretation of the type of surface coverage,in order to carry out statistical analysis from the perspective of geography.Large scale topographic map has the characteristics of surface coverage and geographical feature rich information,combining with production practice the effective technical method for a large scale topographic map data used in geographical conditions survey.
