Embodiment
In below describing,, understand the present invention so that cut thoroughly in order to explain rather than, to have proposed the detail such as specific device structure, technology in order to limit.Yet, not it will be clear to one skilled in the art that in having other embodiment of these details and can realize the present invention yet.In other situation, omit detailed description, in order to avoid unnecessary details hinders description of the invention to well-known device, circuit and method.
The embodiment of the invention provides a kind of inspection method and device of reference by location data, has realized the self-check of reference by location data.
As shown in Figure 1, the inspection method of the reference by location data that the embodiment of the invention provides can be applied on the server of producing said reference by location data, can comprise:
101, read in the reference by location data, obtain the geographic position data of description in the said reference by location data.
Wherein, said geographic position data of description comprises with reference to geographic coordinate and corresponding description thereof.
102, obtain and the identical map datum in said reference by location data overlay area according to said reference by location data, generate first reference data according to said map datum.
Wherein, said first reference data comprises map geographic coordinate and corresponding description thereof.
103, said geographic position data of description and said first reference data are mated.
In the present embodiment, said said geographic position data of description and said first reference data are mated, can specifically comprise: extract the reference geographic coordinate in the data of description of said geographic position; Obtain fall into said be the center of circle with reference to geographic coordinate, predeterminable range is first reference data in the overlay area of radius; Whether the description of judging first reference data fall into the overlay area is consistent with the corresponding description of the reference geographic coordinate of said geographic position data of description.Optional; Under said reference by location data demand precision condition with higher; Also can be directly reference geographic coordinate through said geographic position data of description find first corresponding in the map datum reference data, both description is compared, judge whether unanimity.
104, if exist with the description of the map geographic coordinate of said first reference data inconsistently in the data of description of said geographic position, extract said inconsistently, generate the first difference data of description with reference to geographic coordinate and description thereof with reference to geographic coordinate.
What be worth explanation is; Said reference by location data can be Traffic Message Channel (Traffic Message Channel; TMC) reference by location data are Chinese Real-time Traffic Information (Real-Time Information of China, reference by location data RTIC) perhaps.
In the present embodiment, the said first difference data of description can exist with the form of key point, promptly through a certain road of a certain central point representative in the road.As shown in table 1, comprise the X coordinate, Y coordinate, (X, Y) coordinate points road corresponding.
Table 1: the first difference data of description is enumerated table
Can know through table 1, exist first reference data in above-mentioned geographic position data of description and the map datum inconsistent in the reference location data.Wherein, first title and the second title road corresponding are intersected with said link name road corresponding respectively, if only have first title, what explain that coordinate points representes is the intersection of the link name road corresponding and the first title road corresponding.For example:
In (114.59844,37.59752) expression phoenix street, from the phoenix street with roll the Xiu Fang intersection and begin to phoenix street and the road information that faces one section road till the intersection, road.
| The X coordinate | The Y coordinate | Link name | First title | Second title |
| 114.59657 | 37.61548 | The phoenix street | Roll and embroider the mill |
In (114.59657,37.61548) expression phoenix street, phoenix street and the road information that rolls the intersection of embroidering the mill.
The inspection method of the reference by location data that the embodiment of the invention provides; Since through obtaining the reference by location data overlay area corresponding map data check reference data consistance geographical with reality, inconsistent as if existing with reference to geographic coordinate, it is extracted; Generate the first difference data of description; Can the said first difference data of description be offered the staff, make the staff carry out next step affirmation or repair, confirm or reparation no matter be to it; The geographic position that its first difference data of description covers will reduce artificial work greatly much smaller than the geographic position that reference location data covers.
