地表覆盖与国土三调地类图斑数据差异性分析

Differentiation Analysis between Geographic Land Cover Data and the Third National Land Survey Land Use Data

地表覆盖数据是基础性地理国情监测的重要成果之一,与国土调查地类图斑数据进行差异化分析,可满足相关政府部门对数据演变与内涵解读的迫切需求。基于此,本文重点分析地表覆盖数据与第三次国土调查地类图斑数据间的分类差异,构建分类映射体系,并实现了两类数据间的差异性分析方法,为自然资源监测提供方法与数据支撑。

Geographic land cover data is one of the important results of fundamental geographical conditions monitoring.The differentiation analysis of land cover data and land use data can meet the relevant government departments’pressing needs to read data’s evolution and its connotation.Based on this,this paper focuses on the analysis of the classification difference between geographic land cover data and the third national land survey land use data,builds a classification mapping system,and realizes the difference analysis method between the two types of data,,which provides methods and data support for natural resources monitoring.
