摘要
SPOT5因为具有很高的分辨率,在土地变更调查中有着广泛的应用。对于不同的用地类型,SPOT5的分辨能力也不同,本文利用SPOT5影像室内判读发现的变化图斑与实际变化情况进行对比,介绍了SPOT5卫星影像在北京大兴区土地变更调查实际应用中的具体方法。
SPOT 5 image is widely used in the investigation of land use changes because of its high resolution. But when applying to different kinds of land use, the resolution of SPOT 5 image can be different. This article compares the speckle pattern changes on SPOT 5 image discovered through in-house recognition and reading with the actual changes, and introduces the concrete methods of applying SPOT 5 satellite image to the land use changes investigation carried out in Daxing region of Beijing
