利用高空间分辨率卫星遥感数据制作影像交通图

Traffic Image Map Using High Spatial Resolution Remote Sensing Data

从高分辨率卫星遥感影像图中可以获取大量与交通规划、控制与管理相关的信息,如土地利用、交通小区人口、城市道路网络、交通流量分布、交叉口类型、停车场分布、建筑密度和容积率,甚至主干道路渠化信息等。制作遥感影像交通图能够直观、生动、形象地表述这些信息,并能实现一图多用、一库多用。本文就高分辨率遥感影像交通图的优点、内容、制作的技术路线,以及若干关键技术进行了探讨。

A lot of information related with transportation can be extracted from high spatial resolution remote sensing image, how to describe them is important.In this paper, the technique route of making traffic image map using high spatial resolution remote sensed data is put forward, and some key techniques are discussed including the selection of spatial and pixel resolution, continuous updating, image mosaic and color match.
