摘要
随着高分辨率卫星影像在城市规划设计与管理中的广泛应用,由于AutoCAD无法直接加载浏览高分辨率、大数据量的影像文件,给实际使用造成了一定的困难。通过借鉴Google Map的金字塔数据组织模型,建立线性四叉树索引,实现了在AutoCAD中,方便快捷地调取和浏览有空间定位的影像,从而实现了规划成果与影像的叠加调阅。
With wide applications of the high-resolution satellite images in urban plan design and management,some practical applications met some difficulties because AutoCAD can not directly load and browse high-resolution,massive data image files.Using the Google Map pyramid model of data organization for reference and establishing linear quadtree index,we implemented quickly acquiring and browsing the images with a spatial location,and fulfill the overlay of the plan data and image in AutoCAD.
