摘要:
WorldView-2是世界上首颗能够提供8个波段多光谱数据的高分辨率商业卫星。在对WorldView-2影像8个波段的光谱特征充分分析的基础上,运用WorldView-2影像的地物样本库,并利用面向对象的信息提取技术,分析典型地物的光谱、纹理、几何等特征,提取耕地、林地、园地、水域、道路、居民地及工矿用地等典型地类,验证WorldView-2卫星8波段数据的信息提取效应与精度。这对于WorldView-2影像在测绘、国土、环境等行业,以及国家大型项目(如地理国情监测)的深入应用具有积极的推动意义。
WorldView-2 is the first commercial high-resolution satellite to provide 8 spectral sensors in the visible to near-infrared range. Based on analyzing the 8 Spectral features of WorldView-2 and researching on the sample feature libraries of WorldView-2 image, this experiment tried to extract the data on land, woodland, garden plot, water, road, residential area and industrial land etc., and applied the object-oriented information extraction technology, in order to check the information extraction ability and the precision validation of WorldView-2 data. WorldView-2 image has a positive influence on in-depth application in mapping, land, environment industries, etc. and national project (such as geographical condition monitoring).
