Remote sensing of spatial patterns of urban renewal using linear spectral mixture analysis: A case o
It is very important to integrate remote sensing with urban geography that the spectral mix- ture analysis technique is applied to urban land cover evolvement and its eco-environmental effect. Urban l

A robust and rapid algorithm for generating and transmitting multi-resolution three-dimensional mode
Recent advances in 3D spatial data capture, such as high resolution satellite images and laser scanning as well as corresponding data proc- essing and modeling technologies, have led to the generation
