摘要
民国地形图数字建档是利用民国的纸质地形图经扫描、几何纠正、图像处理和数据压缩后形成的栅格数据文件,是模拟产品向数字产品过渡的一种产品形式,它是现有纸介质地形图以数字方式存档和管理最简捷的形式。本文主要介绍了民国图建档的生产,对生产流程每个环节都加以分析,并提出自己的见解。
The building digital archives for topographic map in the period of the Republic of China is the raster data files from the existing paper topographic map after the scanning, the geometry correction, image processing and the data compression. It is a transition product between analogue product and digital product. It is the simplest method to store and manage the existed paper map in digital mode. This paper mainly introduced the production of building archives for the maps in the period of the Republic of China, analyzed each link of production processes, and proposed own opinions.
