Abstract

The invention relates to an urban ground object coverage information determination method and device. The method includes: according to a plurality of groups of spectral data corresponding to a plurality of first ground object coverage types of the to-be-studied area, and obtaining a similarity value between every two spectral data in a group of spectral data corresponding to the first ground object coverage type, subdividing the first ground object coverage type by comparing the similarity value between the two spectral data with a set threshold, and accurately identifying ground surface coverage information in the research area according to the subdivided ground object coverage type. Compared with the prior art, the method has the advantages that the ground surface coverage information in the research area can be accurately recognized, and accurate and reliable basic data are provided for research on urban fine management, urban micro-ecology, urban ecological space structures and the like.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method and device for determining coverage information of urban features. Background technique [0002] Impervious surface refers to an artificial surface feature through which water cannot penetrate into the soil. It is mainly composed of roads, parking lots, squares, roofs and other buildings. The distribution and coverage of impervious surfaces can reflect the degree of regional urbanization and the degree of ecological environment change, which is of great significance to the assessment of urban ecological environment and the monitoring and management of urbanization process. [0003] However, because urban impervious surfaces often contain a variety of building materials, the existing classification and recognition technology cannot accurately identify specific urban land cover information.
