Embodiment 1

[0054] In Embodiment 1 of the present invention, a method and device for upgrading navigation data are provided. The method for upgrading navigation data is to update the updateable element data in basic navigation data directly using an upgrade package. After completion, the navigation terminal device directly loads the updated basic navigation data, and the latest navigation data can be seen, thereby realizing the upgrade of the navigation data. The navigation basic data upgraded once can be used as the navigation basic data for the next upgrade, and can be upgraded again.

[0055] Such as figure 1 As shown, the method for upgrading navigation data provided by Embodiment 1 of the present invention includes the following steps:

[0056] S11. Obtain an upgrade package corresponding to the basic navigation data.

[0057] The navigation basic data includes the data of each element of the geographic object, and each piece of element data includes: the identification of the elem...

Embodiment 2

[0136] In the second embodiment of the present invention, a navigation data upgrading method, loading method and device are provided. In the second embodiment, the navigation data is in the form of "basic navigation data + validity file". The method for updating the navigation data uses a method of updating using a validity file.

[0137] The difference between this method and the first embodiment is that the navigation basic data itself does not change (here, the no change is only for the second embodiment, in the implementation of the present invention In other implementations of the example, even if the form of navigation basic data + validity file is adopted, the navigation basic data itself can be updated in the form of an upgrade package, for example), and the update of the entire navigation data is realized through the validity file.

[0138] The validity file is generated for the invalid element data in the basic navigation data. When the validity file is obtained and ...

Embodiment 3

[0235] Embodiment 3 of the present invention is aimed at a specific implementation method and a corresponding implementation method when the navigation data to be upgraded exists in the form of "navigation basic data + validity file" and needs to be converted into a separate navigation basic data after the upgrade. device.

[0236] In the method for updating navigation data provided by Embodiment 3 of the present invention, the navigation data includes navigation basic data and validity files, and the method for updating navigation data includes converting the validity file into an upgrade package for navigation basic data, and Update basic navigation data.

[0237] The upgrade package for converting validity files into basic navigation data refers to,

[0238] The deleted part of the validity file is extracted from the validity file and converted directly. For example: convert {-, 9} into an upgrade package {-, 9} from the validity file.

[0239] The addition and modificat...

Abstract

The invention discloses an element level updating method for navigation equipment. It is assumed that an element A needs to be updated, two updating modes are suitable for the element A, the first mode is BASE+DELTA, the other mode is BASE, and the updating modes are selected according to the data size, the data organization structure, the relevance with other elements and other factors. In the first mode: BASE+DELTA, the element is divided into two parts, and during updating each time, the DELTA can be updated while the BASE cannot be updated. In the second mode: BASE, during updating, all data can be updated, only one datum is read, if data capable of being updated exist, update data can be downloaded to the assigned catalog, and the downloaded data need to be managed. The element level updating method has the advantages that changing is frequent, and a small number of core elements need to be updated. One mode or the combination of the two modes can be selected according to the actual situation, and the updating process is achieved. Under the condition that the network support is not available, local updating is selected, and flow is saved.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a navigation data updating method, loading method and device. Background technique [0002] In the process of navigating with a terminal device with navigation function, the user may not be able to reach the desired destination because of the surrounding new residential areas, newly opened large shopping malls, or because of old inaccurate navigation data. , or it may be because of the newly planned roads in the city that it has been delayed in adding to the route planning, resulting in a poor user experience. Providers of various navigation software are also aware of the importance of new data for end users. [0003] However, due to the rich content of the navigation data, it is an urgent problem to be solved in which way to update the navigation data, which not only meets the user's update needs, but also does not burden the navigation software provider with the...
