Wherein, the triangulation (Delaunay triangulation is passed through to the two-dimensional coordinate data Algorithm also known as Delaunay Triangulation), gridding processing is carried out, needs to meet two important criterion；First, empty Circle characteristic: in the corresponding two-dimensional coordinate point of two-dimensional coordinate data, the Delaunay triangulation network of composition is unique (i.e. any four Point cannot be concyclic), other points are not had within the scope of the circumscribed circle of any one triangle in Delaunay triangulation network exists； Second, minimum angle characteristic is maximized, and in the corresponding two-dimensional coordinate point of two-dimensional coordinate data, in the triangulation of formation, The minimum angle that Delaunay Triangulation is formed by triangle is maximum, refers to that in Delaunay triangulation network be " closest to rule Then change " plane grid, in particular to two adjacent triangulars at convex quadrangle diagonal line, after being exchanged with each other, The minimum angle of six interior angles is not increasing.

Gridding processing is carried out to the two-dimensional coordinate data by using the triangulation, so that the institute of composition Stating the plane grid that plane grid is formed and generated by planar triangulations unit is Progressive Mesh, according to described three The characteristic of angle subdivision algorithm enables to have systematicness and uniqueness in the three-dimensional temperature model of subsequent builds, is drawn by illusory The three-dimensional temperature figure bandwagon effect for holding up generation is more preferable.

Step 106: determining that each plane grid unit is in three-dimensional coordinate in the plane grid according to the temperature data Corresponding altitude information in space.

Specifically, the base for the plane grid that above-mentioned acquisition is made of the corresponding plane grid unit of the two-dimensional coordinate data On plinth, further, the plane grid is made of the corresponding plane grid of the two-dimensional coordinate data, and each two dimension is sat Mark data are corresponding with temperature data, then are determined according to the temperature data of each two-dimensional coordinate each in the plane grid Altitude information of the plane grid unit in three dimensional coordinate space.

Wherein, the altitude information is longitudinal height value of the temperature data in three-dimensional coordinate, for example, in the heat Degree has 50 people, the corresponding coordinate points of the two-dimensional coordinate data of place A are according to the population support for being each place at the A of place (3,3), each unit indicates 10 people in three dimensional coordinate space, then altitude information of the place A in three dimensional coordinate space is 5, right The three-dimensional coordinate point answered is (3,3,5).
