多源数据融合的自然资源地理实体构建方法
Construction method of geographic entities of natural resources through multi-source data fusion
摘要
Abstract
This paper focused on the issues of independent and overlapping data from basic mapping and natural resource survey and monitoring.By analyzing and comparing the characteristics of major data sources such as 1:10 000 and 1:50 000 basic geographic information data,and the Third National Land Change Survey data,it proposed a method for constructing geographic entities of natural resources through multi-source data fusion according to the requirements of building geographic entities for real-world three-dimensional(3D)China.Bayi District and Zayu County,Linzhi City,Xizang were selected as pilot areas for verification,resulting in the formation of a"one map"dataset.While meeting the management needs of natural resources business,it provides a broader spatial positioning framework and analytical foundation for the construction of a 3D"one map"of natural resources.关键词
