摘要
国家基础航空摄影资料是生产地理信息产品最原始、最基本、最宝贵的成果。利用现代存储技术解决生产中的航片扫描数据成果,是我国基础测绘任务之一。本文概略介绍了正在进行的国家基础航摄资料数字化与建库项目的资料情况,并对生产DLG,DOM中使用基础航空摄影扫描资料的存储问题做了分析和探讨。
The national basic aerial photogrammetry data is the original, basic, and valuable results to produce Geomatics products. It is one of the basic surveying and mapping tasks to store the scanning results of aerial photograph using advanced storage technique. This paper briefly introduced the datum status of the digitization and database construction of national basic aerial photogrammetry data. Then it also analyzed and discussed the storage problem of basic aerial photograph scanning data which is used to producing DLG and DOM.
