Abstract
A method for making texture symbols of a land use classification map is disclosed in the disclosure, including: capture of texture materials; extraction of main colors; color clustering; extraction of a texture skeleton; tile effect removal; and establishment of a texture library. The disclosure has the following advantages: definitions and classes of texture symbols are provided, and a procedure of making texture symbols is made clear; used natural texture symbols and symbolic texture symbols have clear semantic meanings, facilitating information transfer of the map; the quality and layering of the map are improved; the texture symbols can be directly used for production, to provide a fundamental support for survey and mapping of land use, and also to provide a solution for large-scale result mapping of natural resource survey. The expression of thematic maps of current land use classification is improved.
