Map symbol standardization realization method and system based on self-adapting mechanism

Abstract

The invention discloses a map symbol standardization realization system based on adaptive mechanism. The realization system comprises a user cognitive information collecting unit, a map symbol classifying unit and a map symbol standard formulating unit, wherein the user cognitive information collecting unit is used to collect the cognitive information of users on map symbols; the map symbol classifying unit is used to classify the map symbols according to the cognitive information of all kinds of users on map symbols; and the map symbol standard formulating unit is used to separately process the map symbols according to the classification of the map symbols and formulate a map symbol standard. Correspondingly, the invention discloses a map symbol standardization realization method based on adaptive mechanism. By using the method of the invention, the map symbol standard can more satisfy the cognitive rules of users, thus greatly increasing the scientificalness of the map symbol standard and the degree of acceptance of users.

Description

technical field [0001] The invention relates to the field of computer graphics and map symbol standardization, in particular to a method and system for realizing map symbol standardization based on an adaptive mechanism. Background technique [0002] In order to ensure the consistency and accuracy of geographic information perception and cognition, the normalization and standardization of map symbols are very important. Surveying and mapping scholars, cartographers, industry experts and relevant departments have conducted in-depth research on this issue and formulated corresponding standards, such as GB / T 17695-1999 "General Symbols for Public Information Graphic Symbols for Maps" and its replacement standard GB / T 17695-2006 "Public Information Graphic Signs for Printed Matters", CH / T 4015-2001 "Basic Regulations for the Establishment of Map Symbol Databases", etc. These standards are based on the research results of cartographers and surveying and mapping scholars, and th...

AI Technical Summary

Problems solved by technology

[0005] (1) Users still understand map symbols according to their own cognitive habits, and there are many gaps with the meanings of map symbol-related standards

[0006] (2) After the promulgation of the map symbol standard, there are few users for a long time, that is, it takes a long time for users to accept the standard

[0007] To sum up, the existing methods for realizing the standardization of map symbols obviously have inconvenience and defects in actual use, so it is necessary to improve them.
