| 摘 要： | 随着测绘技术的迅猛发展，内业处理已全面进入数字化阶段，但传统的外业调绘方式已经成为地理信息数据快速更新的“瓶颈”，不能完全满足现代测绘的需要。本文总结了数字调绘系统与传统调绘方法的各自优缺点，设计了一种数字调绘系统。该系统作为一个易操作的平台，降低了劳动强度，提高了数据精度，节约了生产成本。数字调绘为地理信息数据的快速更新提取提供了一种较好的技术手段，必将是今后航测外业的发展方向。

| Abstract: | With the rapid development of surveying and mapping technology, office operation of geographic information has entered the stage of digital processing, but the traditional field annotation has become the bottleneck of quickly updating the GIS data, which can not fully meet the needs of modem surveying and mapping. This paper summarizes the advantages and disadvantages of digital field annotation and traditional methods, designs a digital field annotation system which is easy to operate, reduces labor intensity, improves data accuracy and saves the cost of production. The digital field annotation that provides a better means of quickly updating geographic information will be the future direction of aerophotogrammetric field work. |
