Abstract

The invention provides a method and a medium for extracting green degree space of an urban agglomeration. The method comprises the following steps: acquiring high-score remote sensing data of urban agglomeration and extracting land cover data of urban agglomeration; Obtaining the social perception data of urban agglomeration, and extracting the social function attribute data of urban agglomerationland; According to the cover data and social function attribute data, the land of urban agglomeration is classified, and the information about the land and greenness of urban agglomeration is obtained. According to the classification information, the greenness of urban agglomeration is extracted. The present invention solves the problem that only a single remote sensing data can obtain the land cover information in the related art, and the social function attribute of the urban green space cannot be obtained, and realizes the statistics and research of the urban agglomeration green space containing the social function attribute.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a method and medium for extracting urban agglomeration green spaces. Background technique [0002] With the development of remote sensing technology, the method of urban greenness mapping by means of remote sensing has attracted the attention of many researchers. There are two main methods of extracting urban green space: one is based on pixel classification, for example: Ouma et al. combined spectral and spatial information to classify Quickbird images and extract urban green space. The results show that this method can significantly improve The accuracy of urban green space extraction; Trisakti, B used a pixel-based method to classify Pleides images with supervision (MLEN) and unsupervised (ISODATA), and classified urban green space according to coverage; Feng, Q et al. Methods Texture analysis and random forest classification were carried out on UAV aerial images, and t...
