摘要
本文以聊城市为例,在"数字聊城地理空间构架建设与应用示范项目"的支持下,详细介绍了正射影像图的制作过程及注意事项,为今后航测正射影像的生产制作提供了方法与依据。随着航空摄影技术的发展与普及,大比例尺正射影像图以其丰富的内容,清晰直观的效果一步步丰富传统地形图;以正射影像为底图的航测线划调查图大大提高了外业调绘的效率及野外补测的精度。
With Liaocheng City as an example,supported by the Digital Liaocheng Geographic Space Frame Construction and Application Demonstration Project,this paper gave a detailed introduction to the making process of normal reflection image and matters needing attention and provided method and basis for production of airborne survey normal reflection image in the future.With the development and popular use of airborne photography technology,big-scale normal reflection image has step by step enriched traditional topographic map by its abundant contents and direct vision results.The normal reflection image-based airborne survey line map has greatly improved the efficiency of field surveying and the precision of field supplementary surveying.
