利用高分辨率遥感图像提取建筑物阴影信息初探

Extracting Building Shadow Information from High Resolution Images

首先对上海市中心城区遥感影像建库,把众多的遥感影像数据组织起来,以方便管理和使用.在此基础上,利用GIS和RS技术,对遥感数据解译处理,提取建筑物阴影信息,从而为估算建筑物高度值作准备.

First, the paper builds database of remote sensing images in the core city in Shanghai, organizes numerous images data for management and use. On this condition, we interpreted the remote sensing images in order to extract building shadow information using GIS and RS methods; then we can estimate the building height later.
