Problems solved by technology

However, the geographic environment elements may be convex polygons, concave polygons, or even compound polygons containing one or more holes. In this way, the complexity of the traditional polygon clipping method will be greatly increased, and the efficiency of the algorithm will be greatly improved. reduce

Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] The steps of modeling the terrain attributes of wargame maps are as follows:

[0042] 1) The wargame map adopts a regular hexagonal grid, that is, a hexagonal grid;

[0043] 2) Determine the geographical environment elements involved in wargame map modeling;

[0044] 3) Calculate the capping area ratio of each geographical environment element to the hexagonal grid:

[0045] a. Set the size r of the grid matrix, determine the circumscribed rectangle surrounding the area where each geographical environment element is located, rasterize the circumscribed rectangle to form the initial grid matrix, and identify all the grid points of the initial grid matrix as 0;

[0046] b. Determine the situation that each geographical environment element covers the initial grid matrix, if the grid point covers the geographical environment element, the...

Abstract

The invention relates to a method for modeling the terrain property of a Wargame map by a grid matrix. The method comprises the following steps: firstly, determining an orthohexagonal grid form, i.e., a hexagonal grid, of the Wargame map, and selecting geographical environment factors which participate in modeling the terrain property; then, according to the dimension of the matrix grid and an externally tangent rectangle which surrounds each geographical condition factor, establishing an initial grid matrix on the basis of the geographical environment factors; then, determining an amount of grid points which simultaneously press and cover the geographical environment factors and the hexagonal grid in the grid matrix, and combining with the area of the hexagonal grid to calculate a pressing and covering area ratio of each geographical condition factor to the hexagonal grid; and finally, according to a terrain property judgment rule, determining the terrain property of the hexagonal grid. Through the method, the complexity of modeling the terrain property of the Wargame map is effectively lowered, and the efficiency of modeling the terrain property of the Wargame map is improved on the premise that modeling precision is guaranteed.

Description

technical field [0001] The invention relates to a method for establishing terrain attributes of a wargame map by using a grid matrix. technical background [0002] A wargame map is a rough description of the geographical environment under certain conditions. It is used to assist the commander or combat model to locate the spatial position and determine the spatial attributes during the wargame deduction process; the process of covering the grid and determining the attribute information on the geographical environment is called For "terrain quantization" or "wargame map modeling". Wargame map modeling refers to the process of processing geographical environment data from different sources, such as digital map data, elevation data, slope data, and topography data of military positions, into wargame map data suitable for wargame deduction systems. However, the existing literature on wargame map modeling shows that there are not many researches on wargame maps, and most of the ...
