摘要
栅格目录具有保持单幅栅格数据参考坐标系独立性、无缝管理数据、独立存储等特点。这些特性正好符合历史地图信息化的需要,也有利于实现统一管理和与现势地理信息的集成。历史数字栅格数据建库工作是在完成了数字化扫描、坐标配赋以及元数据采集等准备工作,利用自主研制的软件进行的。
Raster catalog can keep the independence of reference system, manage data seamlessly, and to be stored independently. These characteristics are just according with digitization for the history graphics, and are propitious to manage data uniformly, and integrate the newest graphics information. In order to put the history DRG into the database by the particular software, several works should be done firstly, such as digital scanning, coordinate admeasuring, and metadata collection.
