Abstract

The invention relates to an urban surface cover fine classification method and device based on a remote sensing image. The method includes: carrying out pixel-level fusion on the Landsat data, the spectral index and the surface temperature; and obtaining a new image fused with various information as input data of the model, extracting corresponding spectrums from the spectrum library in combination with a three-layer classification system to serve as training samples of the first classification model, the second classification model and the third classification model, and calculating abundanceof subdivided ground object coverage types in pixels by using a multi-layer model. Compared with the prior art, the method and device have the advantages that fine classification of the sub-pixel scale of the ground object coverage type is realized, and the precision of urban ground surface coverage classification of the remote sensing image is improved.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method and device for finely classifying urban ground cover based on remote sensing images. Background technique [0002] Cement, asphalt, masonry and other artificial ground features in the city have replaced the original natural form near the surface, forming a highly connected, complex structure, and multifunctional artificial ground feature covering device. The coverage of these artificial ground objects provides the city with social, economic, cultural, infrastructure and public service conditions, but at the same time it also produces obvious ecological stress and ecological effects, affecting the urban ecological spatial structure, thereby affecting the ecological environment carrying capacity of the urban agglomeration . Secondly, different types of urban man-made ground objects have different service life and aging rates. Their distribution, management ...
