Example Embodiment

[0065] Example one:

[0066] If the camera data content includes speed limit cameras, mobile speed measurement, traffic light cameras, non-motorized lane cameras, bus lane cameras and other types. The customer of navigation terminal A believes that all types of cameras displayed on the navigator will make the driver feel too dense and affect the driver's experience, and the driver pays more attention to the speed limit camera during actual driving. The customer requires that only the data content of the speed limit camera is provided, and other types of cameras are deleted. The camera data model and content are shown in Table 2 and Table 3:

[0067]

[0068] Table 2 Camera data model table

[0069]

[0070] Table 3 Sample table of camera content record

[0071] Because customer conditions are clear and easy to implement, you can directly use SQL statements to query Table 1 to obtain all CAMERA_IDs that are not speed-limited cameras. The sample SQL statement can be "SelectCAMERA_IDf...

Example Embodiment

[0077] Embodiment two:

[0078] If the data specification standard stipulates that two consecutive orders at high speed should be made as ordinary continuous if the distance is within 600 meters, but the navigation terminal A customer thinks that two consecutive orders at high speed should not be made as ordinary continuous if the distance is within 300-600 meters. Disagreement. The customer requires that only the normal continuous divergence data content of two consecutive orders with a divergence distance within the range of 100 meters to 300 meters is sufficient, and the normal continuous divergence relationship exceeding 300 meters is deleted. The divergent data model and content are shown in Table 6 to Table 13:

[0079]

[0080] Table 6 Different data model table

[0081]

[0082] Table 7 Different types of data model table

[0083]

[0084] Table 8 The data model table of the divergent relationship passing road

[0085]

[0086] Table 9 Road geometry information data model tab...

Abstract

The invention provides a method and device for modifying electronic map relational data. The modifying method comprises the steps of acquiring relational attribute information of to-be-deleted data; performing data query and extraction in a database in an intermediate data format according to the relational attribute information of the to-be-deleted data; constructing a relational data modification list according to the data obtained through query and extraction, wherein the relational data modification list comprises relation IDs for expressing identifiers of the to-be-deleted data and relational types for expressing types of the to-be-deleted data; according to the relation IDs for expressing the identifiers in the relational data modification list, deleting data corresponding to the relation IDs from an original data attached list for compiling final data formats, and forming a current data attached list for compiling the final data formats. According to the scheme, when navigation electronic map data are modified according to customer requirements, the difficulty is small, the quality risk is low, and the implementing cost is small.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a method and device for modifying electronic map relational data. Background technique [0002] With the advancement of science and technology, navigation systems are more and more widely used in the automotive industry. For the navigation system, the navigation electronic map data used for navigation is an important part of it. The production cycle of traditional navigation electronic map data includes at least product design, production planning resource organization, data collection in the field, production of navigation database in the office, comprehensive inspection of data logic, conversion of intermediate data formats, compilation of final data formats, product testing and verification, etc. process. Traditional navigation electronic map products have many production processes and long update cycles. Moreover, for specific navigation data production companies, data s...
