摘要

日本数字地图协会(JDRMA)于1988年开始建设全日本数字地图数据库。第一个数据库于1989年完成，因此于1990年开始增订。有两种数据源用于更新JDRMA数据库。一种是新发行的地形图，其中包括道路和其他特征，但不是每年更新。二是来自道路管理人员的信息;它被用来更新道路网络。每年都会收集新开通或改善道路的信息，并用于更新数据库中的道路网。其他信息也用于补充这两个主要信息源。使用道路以外的交通设施文件和用户提供的信息。改进更新程序的调查工作仍在继续。

Updating of digital road map

Japan Digital Road Map Association (JDRMA) started to construct the digital road map database for the whole Japan in 1988. The first database was completed in 1989, and consequently the updating started in 1990. There are two kinds of data sources for updating the JDRMA database. One is the newly issued topographic maps, which include both roads and other features but are not updated every year. The other is the information from the road administrators; it is used to update the road networks. Every year the information of the newly opened or improved roads is collected and used to update the road network in the database. Other information is also used to supplement the two main information sources. Documents of transportation facilities other than roads and information from the users are utilized. The investigation to improve the updating procedure is continued.<>
