城市大比例尺数字影像地图的研制

Large-scale Urban Digital Image Mapping

城市数字影像地图的制作与应用是城市遥感和数字城市建设的重要环节 ,是城市基础空间数据集和城市GIS的重要组成部分 ,其在城市建设和发展中的地位与作用日益高涨。本文就城市大比例尺数字影像地图制作工艺、生产平台、比例尺系列、航摄要求、控制数据、质量要求和应用模式等进行了探讨 ,对比了数字摄影测量系统和商用遥感图像处理系统在城市影像制图中的应用方式 ,认为在现阶段 ,在城市测量单位 ,以基于单片微分纠正原理的图像处理软件为主要制作平台 ,集成其它测量和制图系统以及既有控制数据和地形数据进行规模化的影像图生产具有极大的优势和推广应用前景 。

It's the important process of the city remote sensing and digital that the digital city image maps are produced and applied. It's also the important sector of the city base space data and GIS. The station and action of producing and applying the digital city image maps are gathering steam increasingly in the city construction and development. This paper discusses the cartography technology,manufacture flat, scale setting,photo demand,controlling data,quality demand and application model of digital image maps. Comparing with digital photogrammetry system and commercial remote sensing image disposal system, we think that producing and applying the digital city image maps has great advantages and prospects at present. This is proved through the examples of this paper.
