Irregular urban heat island footprint extraction method based on angle segmentation

The invention provides an irregular urban heat island footprint extraction method based on angle segmentation. Firstly, based on a multi-source remote sensing image, the surface temperature is inverted, a city built-up area is extracted by using a dynamic threshold dichotomy, and then the city form...
