Example one
The embodiment provides a method for generating a navigation map, which comprises the following steps:
segmenting prestored map data according to a preset segmentation rule so as to form a map frame index tree by the segmented map data; the map data includes first map component element data and second map component element data;
organizing the first map component element data and the second map component element data together in predetermined processing units;

and respectively storing the sub-index files of the loaded map frame index tree.
The method for generating the navigation map according to the present embodiment will be described in detail below with reference to the drawings. The method for generating the navigation map according to this embodiment may be used for a vehicle-mounted navigation device, and the vehicle-mounted navigation device mainly depends on a Global Positioning System (GPS for short). The hardware of the vehicle navigation equipment comprises a chip, an antenna, a processor, a memory, a screen, keys, a loudspeaker and the like. Referring to fig. 1, a flow chart of a method for generating a navigation map in an embodiment is shown. As shown in fig. 1, the method for generating the navigation map specifically includes the following steps:
s1, segmenting the pre-stored map data according to a preset segmentation rule so as to form a map frame index tree by the segmented map data; the map data includes first map component element data and second map component element data. In this embodiment, the predetermined cutting rule is to cut the map data in a two-dimensional space by using a cutting capacity threshold value in units of areas or provinces/cities.
For example, the pre-stored map data is two-dimensional space map data of China, the two-dimensional space map data is divided into units of areas or provinces/cities, in this embodiment, the two-dimensional space map data of China is divided into capacity thresholds according to the units of provinces, and in this embodiment, the capacity thresholds are set to 2000Kb, for example. In other words, the two-dimensional space map data of China is firstly divided according to the province as a unit, and then the map data of each province is divided into data blocks with the division capacity threshold value of 2000 Kb.
Wherein the map data includes first map component element data and second map component element data. The first map component data includes a water system, a green space, an administrative area, a road, a lane, a sidewalk, and a map annotation point in the map data. The second map constituent element data includes topological connection data of the road. In this embodiment, the first map component data is also referred to as background display data, i.e., map background display data. The second map component element data is also referred to as road network operation data.
And S2, the map data which are divided to form the map frame index tree of the map frame index tree, namely the first map component element data and the second map component element data are organized together according to a preset processing unit. In this embodiment, the predetermined organization unit is a unit of an area or a provincial/prefectural city/special administrative district/autonomous district. For example, in China, 23 provinces, 4 direct cities, 2 special administrative districts and 5 autonomous districts exist, namely, the first map component element data and the second map component element data in each province, each direct city, each special administrative district and each autonomous district are organized together.
S3, compiling the map data organized according to the preset organization mode into an index file according to a preset format; wherein the index file includes a plurality of sub-index files. In this embodiment, the step of creating the map data organized in the predetermined organization manner as the index file in the predetermined format specifically means that the map data organized in the predetermined organization manner in units of province/prefecture city/special administrative district/autonomous district in step S2 is created as the index file in the predetermined format. The predetermined format is that the specific codes representing each province, each direct prefecture city, each special administrative district and each autonomous district are in one-to-one correspondence with the file target name. In this embodiment, the specific codes of each province, each prefecture city, each special administrative district, and each autonomous district include specific codes of each province, each prefecture city, each special administrative district, and each autonomous district, for example, administrative codes, postal codes, license plate numbers, codes arranged in order of the size of the area, or codes arranged in order of the number of the population from large to small, and the like. For example, Beijing is coded 010 and corresponds to a file having a file directory name of 1. The Shanghai city has a code of 021, corresponding to a file with a file directory of 2. In the present embodiment, the codes are not limited to the above codes, and any codes that can represent provinces, municipalities in direct jurisdictions, special administrative districts, and autonomous districts are included in the present invention. In this embodiment, the index file includes a plurality of sub-index files, that is, a sub-index file of each province, a sub-index file of each prefecture city, a sub-index file of each special administrative district, and a sub-index file of each autonomous district. In this embodiment, the step S3 further includes forming the road and the map annotation point into search data, and linking the road or the map annotation point with the road and the map annotation point included in a coverage map sheet formed by taking the road or the map annotation point as a center of a circle and taking a preset numerical value as a radius. When the road or map annotation point is retrieved, the coverage map with the road or map annotation point as the center of circle and the preset value as the radius (in this embodiment, the preset value is set to be 30KM) is determined through a link manner to retrieve the periphery of the road or map annotation point. In this embodiment, since the map is retrieved by names or pinyin, the map is originally queried according to provinces, and the data is stored in files according to provinces. For the peripheral retrieval, the map sheet covered by the circle is determined by a fixed range (for example, a circle with a radius of 30KM), and then the data of several provinces is determined to be loaded by the map sheet and the corresponding table of the provinces, so that the peripheral retrieval cross-province search can be realized.
And S4, loading the map frame index tree into the sub index files corresponding to the map frame index tree in a one-to-one mode according to the preset processing unit. And loading the map data which are segmented to form the map frame index tree of the map frame index tree, namely loading the first map composition element data and the second map composition element data into sub-index files of each province, each sub-index file of each prefecture city, each sub-index file of each special administrative district and each sub-index file of each autonomous district which are in one-to-one correspondence with the corresponding province, each prefecture city, each special administrative district and each autonomous district.
And S5, respectively storing the sub-index files loaded with the map frame index tree to generate a navigation map, namely, respectively storing the sub-index files of each province, each direct administration city, each special administrative district and each autonomous district, which are loaded with the map frame index tree. Because each province, the city in the direct jurisdiction, the special administrative district and the autonomous district are independently loaded, the navigation map can be independently installed or the map data of partial areas can be independently upgraded according to the requirements of users after being retrieved by the users.
The method for generating the navigation map ensures that the navigation map can be independently installed or independently upgrade the map data of the part of the area required by the user after being retrieved by the user, reduces the occupation of equipment space, reduces the consumption of flow during online map upgrade, and does not need the user to wait for too long time.
