Embodiment Construction

[0038] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following will further explain how the present invention is implemented in conjunction with the accompanying drawings and specific implementation methods.

[0039] refer to figure 1 As shown, the present invention provides a method for designing the mathematical foundation of maps based on visualization, comprising the following steps:

[0040] S1. Import the base map data of the map, and input the range coordinates, determine the range of the rectangular frame to output the map, and obtain the base map data of the range;

[0041] S2. According to the range base map data obtained in step S1, calculate and obtain the initial mathematical basic information, wherein the initial mathematical basic information includes at least the initial map projection, initial projection parameters, initial paper size and initial scale. It can be understood ...

Abstract

The invention discloses a visualization-based map mathematics foundation design method, computer equipment and a storage medium, and the method comprises the following steps: S1, importing base map data of a map, inputting range coordinates, determining a rectangular frame range of the map to be output, and obtaining range base map data; s2, according to the range base map data obtained in the step S1, initial mathematical basic information is obtained through calculation, and the initial mathematical basic information comprises initial map projection, initial projection parameters, an initial paper size and an initial proportional scale; s3, performing visual drawing on the base map data of the map according to the mathematical basic information obtained in the step S2; s4, the operator adjusts the map page which is visually drawn in the step S3 according to requirements, and stores the adjusted mathematical basic information; and S5, processing the base map data by using the adjusted mathematical basic information in the step S4, and storing the processed base map data as map data to be typeset.

Description

technical field [0001] The present invention relates to the field of map drawing, in particular to a visualization-based map mathematical foundation design method, computer equipment and a storage medium. Background technique [0002] The mathematical basis of maps is the mathematical basis for determining the distribution position and geometric accuracy of geographical elements on the map, including map projection, scale, truncation, orientation, graticules, etc. the first priority to consider. A rigorous mathematical foundation is an important embodiment of the scientificity and accuracy of maps, and an important guarantee for maps to have a certain degree of comparison and measurability. For a map, if there is no strict mathematical basis, people can only regard it as a bird's-eye view or a landscape painting, which greatly loses its role. Any map in the strict sense must have a rigorous mathematical foundation before it can be measurable, that is, all maps first establ...
