面向电子地图的履历机制研究

An Approach of Data Tracing for Digital Map Production

基于以数据表记录方式管理的空间数据,提出一种面向导航电子地图的履历机制,探讨数据生产环节、数据履历生成和管理的实现方式,提出各种履历控制、利用方法,解决内、外业信息变更的不透明性,为数据差分、版本履历的生成提供直接前提,并借此在编辑软件中提供前进、撤销等实际功能。

Based on the geographic information managed by tables and rows similar to special database, we propose a data tracing approach for navigation digital map production. The creation and management of data tracing is discussed, and several methods of its control and utilization is present as well. Data tracing can not only solve the opacity of indoor and field information change, but also provide direct precondition for the creation of data difference and versions. It also can provide undo and redo function in ...
