Problems solved by technology

[0007] (1) The drawing process of thematic maps often involves a lot of software, which greatly reduces the drawing efficiency of thematic maps; map makers usually use drawing software such as Adobe Illustrator and CorelDRAW to make thematic maps, but these drawing software are difficult in data processing and data processing. There are deficiencies in analysis. For example, ArcGIS provides powerful data processing and spatial analysis functions, and some data processing and analysis require the use of other professional software
[0009] (3) How to take into account the popular development trend of thematic map drawing and the scientific demand of thematic map is an important problem to be solved in the development process of thematic map; the development of thematic map towards the direction of mass cartography is the inevitable trend of the all-round development of thematic map in multiple fields , is an important measure to meet the large demand and diversification of thematic maps, but the popularization of thematic mapping also poses new challenges for maintaining the scientific nature of thematic maps. Without systematic thematic mapping work, it is easy to produce unprofessional, unscientific, and unable to meet user needs thematic maps

Embodiment 1

[0029] see figure 1 , in the embodiment of the present invention: a model-driven automatic drawing method for thematic maps, including a demand analysis module, a special application model calculation module, a special data transmission module and a general drawing software thematic map drawing module, specifically divided into the following steps :

[0030] Step 1: Conduct a detailed analysis of map usage, expression theme, and user needs through the demand analysis module, based on which a map framework that meets the needs is preliminarily designed, and the basic implementation process of the thematic application model and the original data required by the thematic map drawing module are determined . The related content of thematic map drawing, which includes the content to be expressed by base map elements and thematic elements, the basic layout and composition of thematic maps;

[0031]In this step 1, the requirements analysis module is the most basic module in the metho...

Embodiment 2

[0042] In order to further and better explain the present invention, an example based on the general mapping software AI is also provided, and the thematic map drawing function of AI is expanded. Function extensions and changes exist in the form of plug-ins in AI, and plug-ins are an important part of AI. It can act on the rendering engine and user interface at the same time, and has powerful functions. These plug-ins are managed through the plug-in manager.

[0043] see Figure 2-3 , which includes a cartographic data loading module, a basemap element symbolization and annotation configuration module, a thematic symbol data matching module, a thematic symbol open design and expression module, a drawing design and expression module, and a thematic map layout adjustment module; among them, cartography The data loading module is the basic module of the plug-in, which is used to load the cartographic data required for thematic mapping. The data sources mainly include base map dat...

Abstract

The invention discloses an automatic thematic map drawing method based on model driving. The method comprises a requirement analysis module, a thematic application model calculation module, a thematicdata transmission module and a general drawing software thematic map drawing module are included. Corresponding indexes are obtained by using a designed special topic application model library. A driving mechanism is directly applied to thematic map drawing, so that the time required for work such as spatial analysis, index calculation and thematic symbol design and expression in a traditional drawing method is greatly shortened, and meanwhile, human errors in the index calculation and interpretation process can be reduced to a certain extent. According to the invention, the advantages of common geographic information analysis software, professional application analysis software and general mapping software in the aspects of data processing analysis and thematic map mapping are combined.Powerful functions of each other in the aspects of thematic data processing and analysis and thematic mapping are comprehensively applied, and a thematic map which resonable and meets the requirementsof users is made.

Description

technical field [0001] The invention relates to the technical field of drawing, in particular to a model-driven automatic drawing method for thematic maps. Background technique [0002] The thematic map is a branch of the map in terms of content classification. It expresses more extensive content and more diverse forms of expression. Thematic maps can not only represent the current situation and distribution characteristics of land objects or phenomena, but also express the dynamic changes and characteristics of land objects or phenomena. According to the law of development, the thematic map is more focused on representing one or several elements than ordinary maps. The content and form of the representation mostly serve the theme and purpose of the map. It is more targeted and has a wider range of applications than ordinary maps. [0003] The development of automatic thematic cartography has promoted the innovation of cartographic theory, and the development of modern carto...
