Abstract
The invention discloses a method for polymerizing and rendering mass dynamic data. The system is based on a webpage geographic information system and is combined with a vehicle management system platform to display million-order-of-magnitude dynamic driving vehicles in a two-dimensional map in two modes, wherein the first mode is characterized by displaying in a mark mode, and each mark represents a vehicle; and the second mode is characterized by displaying in an aggregate statistics mode, and each aggregate statistics digit represents the number of vehicles near the space range.
Description
Technical field
The present invention relates to a kind of magnanimity dynamic data aggregation and the method played up, the data of the dynamic magnanimity on a kind of space are carried out the method that play up in spatial clustering and space specifically, and we are referred to as: the polymerization rendering system.
Background technology
Along with the persistent fever of domestic webpage geosystem, increasing industry system platform has been introduced the webpage geosystem.Satisfy the other industry system platform to conventional web geosystem demand outside, higher level demand is more and more proposed.They satisfy and the sign of data at the webpage geosystem, also are not content with the sign of thousand orders of magnitude, but need dynamically, and the order of magnitude is up to ten thousand, even a designation system of last 100,000 up to a million grades.
The webpage geosystem has designation system efficiently for the efficient that indicates, but this is for the general order of magnitude.When sign was thousands of, significantly pausing appearred in Web page system, has a strong impact on page viewers' work efficiency.And traditional webpage designation system all is static, and namely the position of Biao Shiing can not change, and the dynamic change of marker location namely can't be described in the position that change that can't be real-time indicates.
When webpage map system zoom level is moved provincial national level to, the sign of big quantity has taken screen, can't from indicating, these understand useful information, if can carry out attribute selection and at spatial clustering to sign this moment, just can assume overall responsibility for the sign under certain attribute conditions very easily.The time complexity of well-known clustering algorithm can just can wear whole webpage down under thousands of orders of magnitude, more need not put on ten thousand, 100,000,1,000,000 the order of magnitude.
Summary of the invention
The implementation method that the purpose of this invention is to provide a kind of magnanimity dynamic data aggregation and play up.To replace word " sign " with vehicle in the later text description, also the i.e. application of this system under the vehicle management system platform illustrates this method.This polymerization and rendering system are showed the shipping/passenger traffic/dangerous material/special vehicle of magnanimity based on webpage geosystem system at two-dimensional map.The mode of showing vehicle has 2 kinds: a kind of is to show by the form of playing up grille picture, the designation system of the similar webpage geosystem of showing of effect, and this displaying is subsidiary that the prompting frame function arranged, and this function ejects when mouse is suspended in vehicle and is marked with and shows; A kind of is to show by the form of polymerization, carries out the displaying of two-dimensional space aggregate statistics data geographically, gets the distribution statistics situation geographically to make things convenient for the user to assume overall responsibility for vehicle at two-dimensional space.
The present invention comprises a plurality of functional modules altogether, and data exchange module, data compilation module, data query module, data aggregate module, data rendering module, information generation module are wherein arranged.Be specifically:
(1) data exchange module.Because data interaction need be crossed over two platforms, so need a module that data are transferred to the another one platform from a platform.This module mainly is responsible for the vehicle system management platform and is given GIS platform vehicle data.
(2) data compilation module.Because the data magnitude is bigger, in order to improve the response speed of Core Feature, has set up field index, spatial index and statistical index at application function.This module is used for finishing this function.
(3) data query module.This module is mainly used to satisfy on the function Field Sanitization demand and spatial dimension is searched demand.Utilize field index and the spatial index set up to search fast, the collection that bears results uses for data rendering module, information generation module.
(4) data aggregate module.Traditional clustering algorithm is that all data are traveled through, and this module is to carry out under the pattern of carrying out subspace polymerization in advance, when each spatial clustering request, the subspace control of actual needs polymerization has been saved the time complexity of clustering algorithm greatly below 256.This module has utilized the clustering index data to shorten the time of polymerizable functional.
(5) data rendering module.It is the function of an expensive source time-consuming that the vector data of the big data quantity on the space gives that the webpage geosystem indicates, and the rendering module that server end is given in this function unification is played up.Optimization at powerful server, efficient c language and bottom is played up under the help of algorithm, under the concurrent situation of height, only need not consume the vector data that 10 milliseconds of times can render magnanimity, has greatly improved rendering efficiency.
(6) information generation module.Vehicle simply played up to have only to add up at map click vehicle and obtain the more detailed information of vehicle, the realization of this function needs the information of auxiliary judgment vehicle position on grating map.This functional block mainly is to generate vehicle to get relative position in the grating map data.With auxiliary click function and the frame function of floating.
In order to finish above function, also need a http server, webpage geosystem and vehicle management plateform system.
