Application Study on QuickBird Image in Investigation of Urban Land Use Status

By QuickBird remote sensing lmages as major information source,fusing QuickBird panchromatic images and multispectral images with principal component method and through remote sensing image interpretation and field investigation,the land use status of Tanggu District of Tianjin was surveyed.Results showed that QuickBird remote sensing images met the expectations of making large scale map of urban land use status,image fusion made the most of the high spatial resolution of panchromatic images and high spectral resolution of multispectral images,and effectively improved the precision of remote sensing image interpretation.
