Abstract

The invention discloses an air pressure contour line drawing method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining an air pressure value through each meteorological monitoring station; obtaining a variation function according to the air pressure value and the distance between the meteorological monitoring stations; wherein the variation function reflects the relationship between the distance value and the air pressure value; obtaining position information of each grid point of the to-be-drawn air pressure contour line area and a grid formed by each grid point; according to the position information of each grid point, carrying out air pressure interpolation on each grid point by utilizing the variation function; and determining the trend of the isobaric line in each grid by utilizing a preset grid type according to the grids formed by the grid points subjected to the air pressure interpolation, and drawing an air pressure isoline. According to the method and the device, the problems of complicated grid drawing and large calculated amount in the air pressure contour line drawing process in the prior art are solved, so that the air pressure contour line drawing process is simplified, and the air pressure contour line drawing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of pressure contour drawing, in particular to a pressure contour drawing method, device, electronic equipment and computer-readable storage medium. Background technique [0002] The contour line is a smooth curve formed by connecting points with equal quantitative index values ​​of the cartographic object. It is drawn from the points marked on the map representing the quantity of the cartographic object and each integer point is found by interpolation. The quantity difference between every two contour lines is mostly constant, and the quantity change trend of the phenomenon can be judged by the density of the contour lines. The contour method is often used in conjunction with layered coloring, that is, changing the color depth, warmth and darkness to represent the numerical change trend of the phenomenon, making the drawing clearer and easier to read. In addition, digital annotations are often added...
