利用FME进行空间数据库更新的实用方法

An Update Method for Spatial Database Using FME

对空间数据库的更新模式进行探索,将空间数据库按照更新的精细程度分为区域级更新和要素级更新。针对两种方式的更新模式,以SDE空间数据库为例,根据要素空间拓扑关系,使用FME Workbench创建更新模板对数据库数据进行更新。

In this paper, spatial database update mode is studied. According to its fineness, spatial database update is subdivided into regional level update and feature level update. For update mode in two ways, taking SDE spatial database as an example, according feature topological relations, FME Workbench is used to create update templates to update database data.
