基于对象的高精度DEM数据管理方法研究

Research on Object-based High-accuracy DEM Data Management Method

DEM数据是智慧城市建设和管理所需的重要基础数据之一,本文以上海市高精度DEM数据为例,研究了一种基于对象的高精度DEM数据管理方法,可实现多源多精度DEM数据融合管理,解决了特大型城市海量DEM数据管理和应用中存在的精细程度不足、管理效率不高、更新维护不便等方面的不足问题,满足了上海智慧城市建设中规划、土地、水务和气象等多个管理领域的应用需求。

DEM data is one of the important basic data required for the construction and management of smart cities.In this paper,an object-based high-accuracy DEM data management method which can achieve multi-source and multi-accuracy DEM data fusion by using Shanghai′s high-accuracy DEM data as an example.By using the method studied in this paper,the problems of insufficient DEM data management,inefficient management,and inconvenient updating and maintenance in the massive DEM data management and application were solved.The method was applied to urban planning,land management,water management,and meteorological aspects of Shanghai′s smart city construction.
