Method and system for making thematic maps based on layout association model

Abstract

The invention relates to the technical field of map manufacture, in particular to a manufacture method and system for thematic maps based on a format relevancy model. The method has following beneficial effects: as for manufacture of heterogeneous isomorphism thematic maps, a format concept is introduced; a same auxiliary element framework of heterogeneous isomorphism thematic maps can be physically saved; as for manufacture of multiple heterogeneous isomorphism maps with same auxiliary elements and different map elements, formats can be reused fully so that drawing efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of map making, in particular to a method and system for making thematic maps based on a layout association model. Background technique [0002] In the era of information-based mapping, automation and high efficiency are the basic requirements. In the results map of cartography, it can generally be divided into two parts: one is the substantive content of the map, called geographical elements; the other is the auxiliary content that explains, explains or modifies the substantive content of the map, called as auxiliary elements. Map trimming (specifically map configuration) is the process of adding descriptive auxiliary elements to geographic features. As a key link in map making, map finishing has an important impact on the efficiency of batch production of thematic maps. [0003] In the process of making thematic maps, it is often necessary to produce a large number of thematic maps with the same layout f...

Problems solved by technology

[0006] (1) The efficiency of heterogeneous and isomorphic map drawing is not high: most of the existing map finishing methods focus on how to improve the efficiency of map finishing on a single map, ignoring the content of reusable auxiliary elements in the production of heterogeneous and isomorphic maps;

[0007] ⑵ Geographic elements are more likely to be damaged: the existing map finishing methods are generally based on geographic elements, or directly add auxiliary elements one by one, or indirectly add auxiliary elements based on the map template

This type of method focuses on the direct modification of geographic elements. In the process of adding auxiliary elements, once the operation is wrong, the original geographic elements will be irreversibly damaged, causing the cartographers to start again, which seriously affects the efficiency of cartography;

[0008] (3) The automation of element layout is low: in the existing map finishing methods, whether it is directly adding auxiliary elements or editing a map template, the position layout of auxiliary elements is mostly adopted in the way of "adding and adjusting one by one", which fails to achieve " One-time” location layout; and in the map fit operation of the map template model, if there is overlap between the geographic elements and the auxiliary elements, the relative position adjustment between the elements cannot be realized, and the degree of automation is low
