Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
As shown in Figure 1, the present invention provides a kind of dynamic and visual method towards multi-source global ocean big data, including with
Lower step:
1) multi-source global ocean big data is obtained, and is pre-processed, the multi-source global ocean big data includes not properly
To static data and with direction dynamic data.
Multi-source global ocean big data refers to the different types of oceanographic data obtained from separate sources.The pretreatment packet
It includes:
101) data normalization.Since original data volume is unfavorable for greatly very much subsequent use, so the number that this method will acquire
According to being reorganized, because inevitably having some exceptional values in data, data normalization, data are defined
Maximum value and minimum value indicate the data greater than maximum value with maximum value, the data of minimum value are represented less than with minimum value.
102) each data are divided into the portion header and the portion data, the portion header stores number in a manner of key-value pair
According to attribute information, the portion data stores the numerical value of each data point, wherein directionless static data passes through one group of portion header
It is indicated with the portion data, band direction dynamic data is indicated by the portion multiple groups header and the portion data, and the portion multiple groups data constitutes a vector.
103) clustering processing is carried out to data: according to characteristic (some data band directions, some data of different types of data
It is directionless) and the longitude and latitude characteristic of the earth data are reorganized, to reduce the redundancy of data file；To mutually similar
The set of metadata of similar data of type different time clusters, and keeps effect of visualization apparent.
Since user sometimes wants the not instead of one group of data checked, the multi-group data of same type different time,
And it is often closely similar between data similar in the time, so this method has carried out clustering processing to data, by similar number
According to cluster is classified as, thus the mixed and disorderly of effect of visualization will not be caused because of much like between data, user also can be clearer
The variation of data is observed, concentration is further analyzed processing to the cluster for wanting to continue analysis.
K-means clustering algorithm is classical one of the clustering algorithm of a comparison, high-efficient due to it, realize it is simple,
So being widely used in big data cluster analysis.Its main thought is exactly the cluster that a given data set and needs divide,
Then nearest cluster is divided into data according to distance function, this process constantly repeats, and until criterion function convergence, that is, meets
Some termination condition.The present embodiment is by k-means clustering algorithm, the otherness that can be more easily visualized between data, from
And it can be handled for specific data, while can also effect of visualization be made to be more clear.
2) one simulation terrestrial network of building, pretreated data are mapped in the simulation terrestrial network, are realized automatic
Visualization.The simulation terrestrial network includes the latitude and longitude from west to east by north orientation south, and the data attribute information is
Data longitude and latitude.
For directionless static data, the attribute information of the portion header storing data in a manner of key-value pair, such as la1,
Lo1 respectively represents the starting longitude and latitude of data, and la2, lo2 respectively represent the termination longitude and latitude of data, and dx, dy respectively represent longitude and latitude
The fractionation unit of degree, even dx, which is 0.25, indicates that every 0.25 longitude has a data, according to la1, lo1, la2, lo2, dx, dy
It can calculate in the data bulk numberPoints, data on warp and weft in the quantity and data of data point in total
Data respectively correspond the numerical value of each data point.The mapping process of directionless static data to simulation terrestrial network can be with
Are as follows: starting point is (la1, lo1), and longitude lo1 is successively increased as unit of dx, and latitude la1 is successively reduced as unit of dy, until
Longitude is added to lo2, and latitude reduces to la2.As shown in table 1, which show the passes between the position and longitude and latitude of data in " data "
System, it is 90 that (90,0) expression longitude, which is 0 latitude, the sequence of data in side digital representation " data " field.
Table 1
For band direction static data, there is a portion multiple groups header and the portion data, for example, sea wind and ocean current only have direction and
Two attributes of numerical values recited, so sea wind and ocean current have two groups of header and data, two groups of data constitute a vector, this vector
Direction just represent sea wind blow to or the flow direction of ocean current, the value of each point on the numerical value representative simulation grid of this vector；
And wave has wave high, average period and three, direction attribute can pass through average period so there is three groups of header and data
The flow velocity of wave is indicated with direction.
Realize that automatic visual specifically includes:
I) visualization of static multi-source global ocean big data；
Because human eye is more intuitive to the perception of color, numerical value usually is indicated with color in visualization application
Variation, i.e., establish a kind of mapping relations between data and color, different data be mapped in different colors.Ocean
The physical characteristic datas such as temperature, Hai Wen, density and salinity are all one-dimensional, so the present invention is using Color Mapping Approach to these
Data carry out simulative display.Here color mapping is divided into two steps, initially sets up a color mapping table, defines the transition of color
Range, for example indicate from yellow to red the variation of temperature, color here, which can be, to be continuously also possible to discrete, is used
Family can could be adjusted to generate color mapping table according to actual needs, then map the data into corresponding color, if
Color table be it is continuous, then can directly specify the variation range [min, max] of data, if color table be it is discrete, can
To specify the color value of representational data, thus the variation of realization color changed to indicate data.
Because the position of each mesh point be it is discrete, i.e., only just have data on specific mesh point, and an ocean
It should be continuous on earth that these physical characteristics, which are shown, it is possible that there is no data in certain positions, in order to obtain these
Data, the present invention devise a kind of interpolation algorithm, i.e., the approximation of current point are calculated according to the value of point of proximity, uses here
Be linear interpolation, the value of current point: g here is calculated by the value of four points around00、g10、g01、g11It respectively represents and works as
Four points around preceding point, gx、gyRespectively represent the longitude error when longitude and latitude of current point is rounded downwards, rx、ryIt respectively represents
The trueness error when longitude and latitude of current point rounds up.
F (x)=g00×rx×ry+g10×gx×ry+g01×rx×gy+g11×gx×gy (1)
Ii) the visualization of dynamic multi-source global ocean big data:
Flow Visualization is mainly used for visualization in scientific computing, its essence is using computer graphics and image
Science data are carried out transformation calculations and drafting and are ultimately converted to image and are displayed on the screen by processing technique, and researcher can be with
The analog result of these science data is intuitively observed, and carries out interaction process, so flow-field visualized is the calculating that studies science
A visual important component part, especially in the simulation of various dynamic datas.Sea wind in oceanographic data, ocean
Stream and wave all have flow behavior, therefore present invention uses flow-field visualized methods to simulate dynamic multi-source whole world sea
The motion conditions of foreign big data.
It is all multidimensional that sea wind, ocean current, wave etc., which have directive data, so this method uses and static data is visual
Change the same color mapping method to indicate the numerical values recited situation of change of dynamic data, uses the method for visualizing pair of fluid form
The dynamic characteristic of these data is simulated.If sea wind and ocean current data are two-dimensional, only direction and size, vector can be used
Field takes out its model, and each data point has a speed and direction, can be decomposed into u component and the side y on a direction x
Upward v component, u, v respectively indicate the speed in the x and y direction, can be with particle come the variation of analogue data, it is transported in this way
Dynamic to be expressed as, tail is to next direction and speed in tow under current direction and speed for particle, thus visually
Has the effect of movement.
Thxe present method defines a kind of methods of Particles Moving, first progress interpolation calculation, because of wind and ocean current and wave
It is all continuous, and the data of mesh point are discrete so needing to carry out interpolation calculation to obtain the position between mesh point
Data approximation calculates the u of current point, v component: here by four points around here using bilinear interpolation
g00、g10、g01、g11Respectively represent the vector of four points around current point, gx、gyThe longitude and latitude for respectively representing current point is downward
Longitude error when rounding, rx、ryRespectively represent the trueness error when longitude and latitude of current point rounds up.
U=g00[0]×rx×ry+g10[0]×gx×ry+g01[0]×rx×gy+g11[0]×gx×gy (2)
V=g00[1]×rx×ry+g10[1]×gx×ry+g01[1]×rx×gy+g11[1]×gx×gy (3)
In order to improve visual accuracy, thxe present method defines a function judge this particle whether definition range
It is interior, because off-limits particle can not be shown on the screen, if particle in indication range, carries out it
Display operation.The place that particle has the place of beginning just to have end, it is impossible to some particle is displayed on the screen always, with
The passage of time has new particle and adds will also disappear come so old particle, so thxe present method defines the life of particle
Period determines the display time of particle on the screen, its age of particle one frame of every movement can add 1 to reach definition until age
Particle annihilation when life cycle.Thxe present method defines initial number of particles, i.e., simultaneously how many bar wind line or ocean current line or wave
Wave is shown on the screen, if it is the movement of this linear flowing of wind and ocean current, is then added newly according to the position of current particle
U, v component of particle update particle position, if it is this movement with ripple effect of wave, then according to the speed * time
(frame)=distance updates wave particle position, while detecting the age of particle, if age is more than or equal to the life cycle of definition
It then re-creates a new particle and replaces original particle.In order to keep movement effects more true to nature, also gradual change can be added to particle
Effect, i.e., the color of old particle can be gradually faded away until disappearing, here by with RGB color similar in background colour and transparency come
It indicates, the old particle of one frame of every movement all can be thin out primary, can thus achieve the effect that one kind is true to nature, while also can be good
Show the alternating of the old and new's particle.
The visualization further includes the display of the statistical chart, radar map and rose figure of data.Traditional ocean visualization is only
Focus on the feature of display data there is no the connection between specific statistical data, cannot intuitively find the variation of data, and this hair
