Embodiment
, should be appreciated that following illustrated preferred embodiment only is used for explanation and explains the present invention, and be not used in qualification the present invention a preferred embodiment of the present invention will be described in detail below in conjunction with accompanying drawing.
Fig. 1 has shown the flow process signal of the incremental update method based on the basic map data provided by the invention, and is as shown in Figure 1:
Step S101, the data plot merchant issues basic map, comprises the last revision basic map, and map datum operator downloads and stores the last revision basic map to home server.User terminal obtains the last revision basic map of map datum figure merchant issue.
Step S102; When map datum figure merchant issues the current version basic map; Map datum operator downloads the current version basic map, obtains the increment map datum through analyzing contrast last revision basic map and current version basic map, and is stored to home server to the increment map datum.
Wherein, analyzing contrast last revision basic map and current version basic map obtains the increment map datum and may further comprise the steps:
Carry out the 1st division to last revision basic map and current version basic map with plurality of grids; Through the figure layer data in contrast last revision basic map and the corresponding grid of current version basic map; Obtain the 1st division and there are differences grid, be the grid that there are differences after dividing for the 1st time;
There are differences grid and divide once more dividing for the 1st time, the figure layer data through in contrast last revision basic map and the corresponding grid of current version basic map obtains the 2nd division and there are differences grid, is the grid that there are differences after the 2nd division;
Until being there are differences grid, the N-1 time division divide once more; Through the figure layer data in contrast last revision basic map and the corresponding grid of current version basic map, the area that the N time of obtaining division there are differences grid is less than or equal to predetermined area;
Wherein, N is a natural number; Dividing for the N time and there are differences grid is the increment map datum, and predetermined area is predefined grid area, and the N time division there are differences grid and be the grid that there are differences after the N time division; If when certain is divided, be divided to the figure layer data that there are differences in two different grid, then the N time division there are differences grid area for there are differences grid area sum.
The increment map datum is set up index information and is stored to home server.
Step S103, user terminal obtains the increment map datum through home server, also obtains the index information of increment map datum simultaneously, according to index information and increment map datum the map on the user terminal is carried out local updating then.
Fig. 2 has shown the incremental update device block diagram based on the basic map data provided by the invention, and is as shown in Figure 2, comprises basic map release unit, map datum monitoring means, map datum analytic unit and map data update unit.
Basic map release unit issue basic map comprises last revision basic map and current version basic map.
The map datum monitoring means detects releasing news of basic map release unit in real time, in time downloads last revision basic map and current version basic map.
Map datum analytic unit analysis contrast last revision basic map and current version basic map obtain the increment map datum, and set up the index information of increment map datum, are stored to home server to increment map datum and index information again.
The map data update unit obtains index information and increment map datum through home server, according to index information and increment map datum local updating is carried out in the corresponding place of the map on the user terminal again.
Fig. 3 has shown the implementing procedure of the incremental update method that the embodiment of the invention provides, and is as shown in Figure 3:
Step S301, map datum figure merchant issues basic map, and version number is V1.
Step S302, user terminals such as mobile phone terminal, navigation terminal or PC terminal are downloaded own required data there to map datum figure merchant, convert the application format data of oneself to, on the terminating machine that is applied in.The client needs diagram data figure merchant's the V1 of basic map version number clearly.
The basic map of step S303, map datum operator storing place diagram data figure merchant issue simultaneously on home server writes down map datum figure merchant's the V1 of basic map version number simultaneously.
Step S304, map datum figure merchant issues basic map once more, and version number is V2, compares with V1 version basic map to have increased a road A and a market B newly.
Step S305; Map datum operator is the V2 version basic map of data plot merchant issue according to the map; And compare analysis with V1 version basic map, and drawing incremental data Δ V1, Δ V1 has comprised the figure layer data information of road A and market B; And set up the search index information of Δ V1, be positioned over home server.
Step S306, whether user terminal monitor server end has new version, if redaction is arranged, downloads to home server to incremental data Δ V1 and index information.
Step S307 sets up the topology information of incremental data on Δ V1 basis, download to whole application data the local storage of user terminal then, navigates, retrieve application etc.
In sum; The present invention has following technique effect: the present invention has realized the real-time update of the map datum of user terminal through the incremental update of user terminal electronic chart; Make map datum trend of the times property stronger; Let the user more can experience the real-time importance of map datum, it is convenient more that the client is gone on a journey.
Although preceding text specify the present invention, the invention is not restricted to this, those skilled in the art can carry out various modifications according to principle of the present invention.Therefore, all modifications of doing according to the principle of the invention all are to be understood that to falling into protection scope of the present invention.
