S120: obtain the terrain information on earth's surface, described transmission line of electricity facility place, build dimensionally table model according to described terrain information.
Specifically, it is possible to obtain the elevation information on earth's surface, the TIN landform according to this elevation information drawing three-dimensional earth's surface according to the terrain information on earth's surface, this Triangulated irregular network model and remote sensing image are overlapped and fit, thus obtaining dimensionally table model.
S130: use graphics engine to build three dimensional spatial scene with webpage connector, load described three-dimensional circuit structure model and described dimensionally table model in described three dimensional spatial scene, build the three-dimensional scenic of described transmission line of electricity.
Wherein, graphics engine can be selected for XNA graphics engine, and webpage connector can be selected for Silverlight (Microsoft's silver light) webpage connector, thus realizing the structure to three dimensional spatial scene.
By using graphics engine to build three dimensional spatial scene, can when loading three-dimensional circuit structure model, corresponding transmission line of electricity facility is pasted corresponding image, thus reflecting transmission line of electricity facility more really, and the three-dimensional circuit structure model of dimensionally table model Yu transmission line of electricity is combined, the position of transmission line structure, shape and space structure relation can be reflected in objective ground, it is achieved the foundation to transmission line of electricity three-dimensional scenic, conveniently transmission line of electricity facility be emulated.
Simultaneously, by using graphics engine to build three dimensional spatial scene with webpage connector, three dimensional spatial scene loads three-dimensional circuit structure model and the dimensionally table model of transmission line of electricity facility, build the three-dimensional scenic of transmission line of electricity, it is capable of the web page display of this three-dimensional scenic such that it is able to the information of transmission line of electricity between multiple equipment that conveniently realizes is transmitted with striding equipment alternately；Pass through transmission line of electricity facility is that who line construction model combines with the dimensionally table model on earth's surface, transmission line of electricity facility place simultaneously, it is possible to the actual scene of solid image ground reflection transmission line of electricity facility more.
As in figure 2 it is shown, the three-dimensional circuit structure model of transmission line of electricity facility includes the geometry vertex information of transmission line of electricity, geometric surface information, mapping coordinates information and material information.Transmission line of electricity facility
Described in described three dimensional spatial scene, load described three-dimensional circuit structure model, including:

As it is shown on figure 3, the step S120 in embodiment illustrated in fig. 1: the method building dimensionally table model according to described terrain information specifically includes:
S310: obtain the elevation information in each place on described earth's surface from the terrain information on described earth's surface；
S320: build the Triangulated irregular network model on described earth's surface according to the elevation information in each place on described earth's surface；
Triangulated irregular network model (TriangularIrregularNetwork, TIN) it is digital elevation model (DigitalElevationModel, DEM) one, it it is a kind of ground model representing ground elevation by one group of orderly array of values form, Triangulated irregular network model can describe surface configuration with the resolution of different levels, can accurately represent more complicated earth's surface with less room and time under specified resolution.Particularly when earth's surface includes big measure feature, during such as features such as geosutures and structure lines, Triangulated irregular network model can process these features more accurately.As shown in figure 12, the Triangulated irregular network model on earth's surface is usually gray-scale map, through step 1.1: resolves the height value of TIN model file, and carries out painted to the terrain model of gray-scale map.
S330: the coordinate corresponding relation according to earth's surface Yu described remote sensing image, searches the remote sensing image unit that each place on described earth's surface is corresponding；
S340: the elevation information in each place described and the resolution corresponding relation of described remote sensing image unit are set；
S350: the resolution corresponding relation according to the elevation information in each place described Yu described remote sensing image unit, by superimposed for the Triangulated irregular network model of described remote sensing image Yu described earth's surface, generates dimensionally table model.
As shown in figure 12, before superposition Triangulated irregular network model and remote sensing image, can through step 1.1: resolve the height value of Triangulated irregular network model, then Triangulated irregular network model is carried out painted, so that the picture after resolving is more life-like, finally perform step 1.2: superposition remote sensing images, in display effect such as Figure 12 shown in the rightest figure.
By the terrain information on earth's surface it can be seen that earth's surface is rugged multiple place constitutes, therefore, it can the elevation information according to each place, earth's surface, build the Triangulated irregular network model on earth's surface, the state that the height on simulation earth's surface rises and falls；
nullCoordinate corresponding relation according to earth's surface Yu remote sensing image，Search the remote sensing image unit that in Triangulated irregular network model, each place is corresponding，Then it is overlapped，In additive process，Remote sensing image needs to carry out Pyramid technology and shows，As shown in figure 13，Remote sensing image is divided into the 0th grade、1st grade and the 2nd grade of three layers，The foundation of layering is the elevation information in corresponding place，Each remote sensing image module above-mentioned is called layering tile，The Pyramid technology of remote sensing image show refer to the same space with reference under，Need to carry out storing and showing with different resolution according to user，Formation resolution is from coarse to fine，Data volume is by the pyramid structure of little arrival，Remote sensing image adopts Pyramid technology to show have two aspect advantages，First，By selecting a resolution similar to viewing area，To needing to carry out a small amount of inquiry and a small amount of calculating，Solve the reading speed problem of big image data；Second, select suitable resolution to display, it is possible to reduce system resources consumption, it is achieved that from coarse to fine to image data, by entirety to fast roaming locally.Owing to Triangulated irregular network model can show surface configuration with the resolution of different levels, remote sensing impression is also adopted by Pyramid technology structure and forms different resolution simultaneously, and therefore TIN and remote sensing image can be overlapped by resolution.
Three dimensional spatial scene, three-dimensional circuit structure model are often different from the ratio of dimensionally table model and coordinate, therefore, in order to realize the smooth loading of three-dimensional circuit structure model and dimensionally table model, as shown in Figure 4, step S130 shown in Fig. 1: in the described concrete steps loading described three-dimensional circuit structure model and described dimensionally table model in three dimensional spatial scene, including:

S430: according to described three dimensional spatial scene and described dimensionally ratio and coordinate corresponding relation between table model, described dimensionally table model is loaded in described three dimensional spatial scene；
Three dimensional spatial scene, three-dimensional circuit structure model are often different from the coordinate of dimensionally table model and ratio, specifically, the ratio of described three-dimensional circuit structure model and described dimensionally table model and coordinate can be set to the ratio in three dimensional spatial scene and coordinate, so that three-dimensional circuit structure model is mutually matched with dimensionally table model, and then transmission line of electricity facility is carried out accurate simulation.
S440: according to described three-dimensional circuit structure model and described dimensionally ratio and coordinate relation between table model, mate described three-dimensional circuit structure model and described dimensionally position between table model；
S450: the type information according to described transmission line of electricity facility, loads the transmission line of electricity facility figure mated with described transmission line of electricity facility.
