Recognizing Urban Functional Zones by GF-7 Satellite Stereo Imagery and POI Data [PDF]
Applied Sciences, 2023 The identification of urban functional zones (UFZs) is crucial for urban planning and optimizing industrial layout. Fusing remote sensing images and social perception data is an effective way to identify UFZs. Previous studies on UFZs recognition often ignored band information outside the red–green–blue (RGB), especially three-dimensional (3D) urban ...
