摘要
在地理国情普查样本点数据的基础上,采用地理国情普查内容分类一级类标准,通过Landsat8 TM和GF-1两种影像数据,借助软件ENVI和ArcGIS,实现对鄱阳湖区生态环境地理信息的提取,建立统一的知识库模型,将各地物类以对象来组织描述,使地物内部的复杂属性与地物间的相互关系清晰化。
Based on geographical conditions census data and standard of geographical conditions survey content classification, we used Landsat8 TM and GF-1 to extract the ecological environment geographical information in the region of Poyang Lake by ENVI5.3 and ArcGIS 10.1, and established the basic model of unified knowledge to describe features as objects, which got the clarity of the relationship and complex interior attributes between every feature.
