It is much smaller.
S13, region division is carried out, and determines the position data of each zone boundary respectively；
In order to construct the threedimensional model in each region, the embodiment of the present invention needs to carry out corresponding region division, determines simultaneously
The position data of each zone boundary is determined respectively；For example, it can be according to the division mode of administrative region come in some city
The division in region is carried out in the two-dimentional geographic model in city；It may thereby determine that the position on the boundary of the threedimensional model bottom surface in each region
Set data.
S14, the incidence relation for establishing each region with corresponding default statistical data；
Default statistical data in the embodiment of the present invention can be GDP data, demographic data, multi-energy data or finance data
The statistical data that equal needs compare.By establishing the incidence relation in each region with corresponding default statistical data, Ke Yifu
Give the data attribute (numerical value including statistical data) of the corresponding statistical data in each region.
S15, altitude information corresponding with the numerical value of default statistical data in region is generated according to preset rules；
In embodiments of the present invention, by the data attribute (number including statistical data of the corresponding statistical data in each region
Value) in general the supplemental characteristic that is considered as altitude information when constructing area three-dimensional model can pass through a default ratio
Example determines the altitude information corresponding relationship of statistical data；The difference of height when in this way can be by area three-dimensional model is come
The contrast effect of statistical data between each region is presented.
S16, the position data according to the boundary in the region, with altitude information corresponding with the region to the region
Textures are carried out, the threedimensional model in the region is constructed；
It is the size according to the numerical value of statistical data in the embodiment of the present invention when constructing the threedimensional model of each region
(height of threedimensional model is determined with the size of the numerical value of statistical data) schematically constructs corresponding three-dimensional mould by textures
Type.
In practical applications, the specific of corresponding threedimensional model is schematically constructed by textures in the embodiment of the present invention
Step may include: the wide height of facade for the threedimensional model for calculating the region according to altitude information, then regular in three-dimensional mould
Normal map is pasted on type facade, threedimensional model is made to have concave-convex sense.
Wherein, the concrete mode for carrying out textures to region can be, and swear using triangular facet subdivision algorithm, by different two dimensions
Data partition is measured into triangular facet, uniquely determines a unified plane in three-dimensional space by triangular facet；In order to
It is further to reduce operation cost, it preferably can also include: that concave polygon dismantling will can be encountered during triangular facet subdivision
For multiple convex polygons, then carry out triangular facet subdivision.
It preferably, in embodiments of the present invention, can also include step, to preset statistical data during textures
Numerical value is parameter, carries out the setting of color to threedimensional model according to preset algorithm, thus can be by the three-dimensional mould of different height
Type is also shown by different colors, to further enhance contrast effect.
S17, according to coordinate system unified in corresponding GIS platform, the three-dimensional mould in each region is set in GIS platform
The coordinate and sitting posture of the bottom surface of type.
It, can be flat according to its corresponding GIS according to the position coordinate data in region after constructing the threedimensional model in region
The coordinate and sitting posture of the bottom surface of the threedimensional model of each geographical information element is arranged in unified coordinate system in platform in GIS platform.From
And corresponding region is shown in the interface of Visualized Urban Outer Prestress management system with three dimensional pattern.Wherein, by the way that three-dimensional mould is arranged
The coordinate and sitting posture of the bottom surface of type can determine that each ground region is specific in the interface of Visualized Urban Outer Prestress management system respectively
For and direction.
It, can be according to the two-dimentional geographic information data in the region in city and default in conclusion through the embodiment of the present invention
Statistical data automatically constructs the threedimensional model of each region in GIS platform, due to the height setting of the threedimensional model in each region
There is corresponding relationship with the size of the default statistical data in the region, therefore the interface of Visualized Urban Outer Prestress management system can be passed through
In the height in each region intuitively see the default statistical data contrast effect in each region.Specifically, the present invention is implemented
Example obtains the two-dimentional geographic information data in default city first, in accordance with the mode of two bit models of building and constructs based on GIS platform
Two-dimentional geographic model；Then, the division for carrying out each region according to actual needs, to obtain the boundary line of each region；
The embodiment of the present invention also constructs the threedimensional model in each region, wherein the altitude information of the threedimensional model in each region and pre-
If the numerical value of statistical data has the proportionate relationship of setting, that is to say, that the numerical value that statistical data is preset in a certain region is bigger, should
The height of area three-dimensional model is higher；When the numerical value of some region of default statistical data is smaller, the height of threedimensional model
Degree is also just corresponding lower.In this way, when each region is arranged in GIS platform according to coordinate system unified in corresponding GIS platform
Threedimensional model bottom surface coordinate and sitting posture after, by observe Visualized Urban Outer Prestress management system interface, not only it can be seen that
Each region specific location and range, and the height showed according to different zones, can also and meanwhile it is intuitive and quickly obtain
Obtain comparing result of each region about default statistical data.
