A method for making texture symbols of land use classification thematic maps

Abstract

The invention discloses a method for making texture symbols of a thematic map of land use classification, comprising: texture material interception; main color extraction; color clustering; texture skeleton extraction; tiling feeling removal; and texture library construction. The advantages of the present invention are: the definition and classification of texture symbols are given, and the production process of texture symbols is clarified; the natural texture symbols and symbolic texture symbols used have clear semantic connotations, and are easier to transmit map information; the texture and texture of maps are improved. A sense of hierarchy; it can be directly used in production, providing basic support for land use survey mapping, and at the same time providing a solution for large-scale mapping of natural resource survey results. Improve the expression of the land use status classification thematic map.

Description

technical field

[0001] The invention relates to the technical field of map symbols, in particular to a method for making texture symbols of land use classification thematic maps. Background technique

[0002] Maps are composed of map symbols, so map symbols are also called map language, which is the basic carrier and medium for people to understand the world. Usually, map symbols include three categories: line symbol, color symbol and annotation (text description on the map, including text and numbers), which are used to represent the spatial distribution, quantity, quality and other characteristics of cartographic objects.

[0003] Generally, line-dash symbols are divided into point symbols, line symbols and surface symbols according to their basic shapes.

[0004] Point-like symbols: usually an overview and abstraction of point-like natural objects, their position has a clear positioning concept, while the size of the symbol only has the concept of classification and has ...
