城市高层建筑遥感调查方法研究——以上海市为例

Study on survey of high-rise buildings with RS a case study in ShangHai

城市建设日新月异,高层建筑则是城市的标志。城市建设现状的调查,尤其建筑现状的调查已刻不容缓,其关键是具有高效的调查手段。本文以上海为例,对城市高层建筑遥感调查方法进行了有益的探索。特别是针对建筑物高度的调查,创新性地提出了基于QuickBird遥感影像的新阴影长度法。该方法具有与影像参数无关及阴影长度计算自动化的特点,因而具有高效、适用范围广等特点。

City feature is changing all the time,and high-rise building is the symbol of city.It is urgent to survey the status of city construction,especially the status of building to find out an efficient way.In this paper,by searching the RS survey high-rise building in Shanghai,we bring out New Shadow's Length Method based on QuickBird RS image.This method is unrelated to parameter of image,and the shadow's length can be easily computed,so it is very effective and adaptable to vast area.
