Embodiment
Embodiments provide the method for a kind of locus index, the method comprises: the data query obtaining terminal to report, according to this data query, determines the first object picture prestored, according to the first object picture, determine the first spatial index region residing for the first object picture; According to the corresponding relation between area of space scope and position data, determine the primary importance data that the first spatial index region is corresponding; Primary importance Plotting data is entered shown first object picture, generates and comprise described primary importance data first picture.The method provided by the embodiment of the present invention can realize the quick response inquired about the position data of monitored object and the display of real-time Density Distribution in Map Services.
Below by accompanying drawing and specific embodiment, technical solution of the present invention is described in detail, be to be understood that, the explanation of concrete technical characteristic in the embodiment of the present invention and embodiment just to technical solution of the present invention, instead of limit, when not conflicting, the concrete technical characteristic in the embodiment of the present invention and embodiment can combine mutually.
Be illustrated in figure 1 the process flow diagram of the method for a kind of locus index in the embodiment of the present invention, the method comprises:
S101, obtains the query argument of terminal to report;
S102, according to query argument, determines the first object picture prestored;
S103, according to the first object picture, determines the first spatial index region residing for the first object picture;
S104, according to the corresponding relation between area of space scope and position data, determines the primary importance data that the first spatial index region is corresponding;
S105, enters shown first object picture by described primary importance Plotting data, generates and comprises described primary importance data first picture.
Specifically, in order to realize the method that the embodiment of the present invention provides, system needs to mark off multiple spatial index region, namely according to the factor of the aspect such as service needed and performance, to global geographic location or specific region according to index region between regular partition clearancen.That is, system carries out spatial index Region dividing to appointed area, obtains N number of spatial index region.Then system judges residing for the position data that system gets by the space arithmetic that JTS provides spatial index region, by the area identification assignment in spatial index region in position data, and sets up the corresponding relation between spatial index region and position data.
Here it should be noted that, the area identification of present position data and previous time point can also compare by system, if when area identification changes, system also will upgrade area identification corresponding to position data.Can ensure that area identification can be corresponding in real time with position data like this, thus ensure the accuracy of the data inquired.
Further, in embodiments of the present invention, play up the generation of picture in order to realize real time position, system is by the time interval according to program setting, and constantly generate the raster data picture of certain time point, this raster data picture is object picture.From memory database redis, obtain the position data of current point in time, start section according to chart portfolio engineer's scale (i.e. the pyramid structure of GIS), thus finally obtain object picture corresponding to each time period.
Further, in embodiments of the present invention, in order to improve the efficiency of image slice, the bottom level of pyramid structure is adopted and first produces an overall object picture by the large region unit expression region of 8*8 (namely under this level), again from this object picture, corresponding picture region spanning subgraph sheet object is intercepted by the expression scope of id under WMTS service regulation under this level to object picture, and be stored to database.Such process is compared to each id region and carries out picture drafting separately, and the data decreased on picture compare the drafting number of times of traversal number of times and picture, because the drafting repeatedly carrying out little picture can more expend the more time compared to intercepting sub-pictures.
Further, in embodiments of the present invention, after establishing the corresponding relation between spatial index region and position time, if when system acceptance is to the query argument of terminal, raster data query interface in system, by the data query based on terminal, determines the first object picture that described terminal is corresponding in picture database.
System by based on the first object picture determined, and according to the first spatial index region that space arithmetic quick position first object picture of JTS represents.After system determines the first spatial index region, the corresponding relation that system will be transferred between spatial index region and position data, then determine that the primary importance data that the first spatial index region is corresponding, primary importance data are now primary importance data corresponding to terminal.
After obtaining primary importance data, primary importance Plotting data is entered the first object picture by system, generates the first picture comprising primary importance data, that is, can demonstrate the current residing position of terminal in the first picture.So after generation first picture, the first picture is sent to terminal by system, the quick response that so just real-time in the Map Services position data to terminal is inquired about and the display of real-time Density Distribution.
