Embodiment 3:
Referring to fig. 2, Fig. 2 is another flow chart that the method for three-dimensional thermodynamic chart is generated the present invention is based on GIS.This method packet
It includes:
Step 301, data preparation.
Thermodynamic chart shows both of which, and one is global schema, another kind is present viewing field mode.Global schema is
All factor datas are involved in operation, display；Present viewing field mode is only that element carries out operation, display in present viewing field.
The point element for having latitude coordinates (lon, lat) and needing thermodynamic analysis attribute value p for needing to show is read first,
Count maximin (i.e. acquisition current visible range, the maximum value of target data (data in the global or visual field) longitude and latitude
(xmax, ymax), minimum value (xmin, ymin)).According to longitude and latitude maximin, the Aspect Ratio of thermodynamic chart rectangle picture is determined.
Then the image parameters (long and wide) for needing to generate according to length-width ratio setting.For example length-width ratio is a, setting picture is wide
Degree be w (generally take screen resolution, such as 1080), then corresponding another edge lengths h=a × w.
Finally according to the correspondence ratio of longitude and latitude and picture, corresponding pixel points position of each element on picture is calculated
(x, y).By taking position where China as an example, calculation formula are as follows:
Step 302, threshold calculations.
To realize better user experience, the present invention adds threshold calculations, modification function in thermodynamic chart realization, so that hot
The display form tried hard to is more abundant, reduces influence of the discrete data to thermodynamic analysis.
According to a factor data set, target data is counted, target data includes target in global object data or the visual field
Data need the maximum value and average of the attribute value p of thermodynamic analysis, when maximum value is much larger than average, generate in proportion
Reference threshold α between one 0~1, while providing maximum reference threshold for the interface of modification, convenient for users to customized,
To calculate as heating power data maximum value pmaxEqual to current data maximum value multiplied by reference threshold α.
Step 303, picture generate.
According to the image parameters of the first step, a blank picture is generated, then the computational element point position on picture
Color, generate heating power picture.It is specific as follows:
A radius is set for discrete point, creates a buffer area；
To the buffer area of each discrete point, from inside to outside using progressive gray scale band (complete gray scale band is 0~255),
It fills from shallow to deep, current grayvalue is current point element value p divided by point element maximum value p in regionmaxMultiplied by 255；
Since gray value can be superimposed, gray value is bigger, and color is brighter, then seems whiter in gray scale band.In practice,
Can choose any channel in ARGB model can be superimposed as superposition gray value hence for the region for having buffer area to intersect
Gray value, thus buffer area intersection is more, gray value is bigger, and " heat " is also got in this block region；
It is to index with superimposed gray value, (such as iris) mapped color in the colour band for having 256 kinds of colors from one,
And image is restained, to realize hotspot graph.
The upper figure of step 304, picture.
According to target region, region includes generating the rectangle of a filling current region, then in the global or visual field
By the heating power picture of generation as on texture padding to rectangle.Horn of plenty three-dimensional thermodynamic chart shows form, and rectangular area can be with
It is set as patch ground or patch building is shown.Wherein patch ground is to show on three-dimensional earth spherical surface；Patch building take into account patch and
Building is pasted, judgement has the place of building to be attached to building surface according to the actual situation, not the place patch ground of building.
Step 305, dynamic generation.
Camera fields of view variation is bound, visual field variation is according to mouse roller event and mouse drag events are monitored, when the visual field is sent out
After changing, 302 are re-execute the steps to step 304.So far the dynamic 3 D thermodynamic chart of complete set is completed.
