Point of interest point of interesting: POl is an institution, system, organization, service place, etc. established for a certain need surface. Hereinafter referred to as POI. 4 Basic content
The basic content of the navigation electronic map should include four major categories of information: road network, background, annotation, and index, and should be able to support the navigation system to achieve: map display and positioning, destination retrieval, route planning, guidance and prompts. Road network information includes road information and node information; background information includes administrative divisions and other geographical features; annotation information includes the name information of important geographical features and roads on the map; index information includes POI and address search information.
4.1 Road Network Information
Road information includes road number, road name, road function level, road form, road width, road direction, road traffic restrictions, etc., and the road geometry is a line; node information includes intersection type, road connection relationship, traffic restrictions, and the node geometry is a point.
4.1.1 Road Information
4.1.1.1 Road Number
Road numbering is implemented in accordance with GB917.1~917.2 and GB/T11708. 4.1.1.2 Road Function Level
According to national standards and taking into account the requirements for road functions in navigation applications, the following road function level definition method is adopted. First-level functional roads, second-level functional roads, third-level functional roads, fourth-level functional roads, fifth-level functional roads, and sixth-level functional roads. The corresponding relationship between road functional levels and the current classification standards is as follows: First-level functional roads: expressways, urban expressways (expressway level); Second-level functional roads: first-level highways, urban expressways, and urban trunk roads; Third-level functional roads: second-level highways and urban trunk roads; Fourth-level functional roads: third-level highways and urban secondary roads; Fifth-level functional roads: fourth-level highways and urban branch roads; Sixth-level functional roads: off-grade highways (internal roads of units, etc.). For the display styles of roads of different functional levels, please refer to Appendix A. 4.1.1.3 Road form
Road forms include exits, connecting roads, bridges, elevated roads, tunnels, ferries, service areas, parking areas, roundabouts, auxiliary roads, pedestrian streets, planned roads, multi-line roads, and single-line roads. a) Entrances and exits: connecting sections, ramps, or lanes at the intersection of two or more roads of different levels, see Figure 1 (see Figure E.1 for examples). b) Connector: A connecting road, tunnel or lane at the intersection of two or more highways or urban expressways, see Figure 2. c) Bridge: A structure used by railways, roads, channels, pipelines, etc. to cross rivers, valleys or other traffic lines. d) Viaduct: A type of bridge, usually with multiple spans. Viaducts often carry traffic elements above the ground. e) Tunnel: A closed artificial structure that allows a traffic element to pass through a natural element or other obstacle from the middle or under it. f) Ferry: A transportation facility that transports people between two fixed locations using a specific mode of transportation (such as ship or train). ) Roundabout: A simple closed one-way ring road in the road network, used to regulate traffic flow at the intersection of roads at different levels (see Figure E.2 for an example).
h) Multi-lane road: A road with a physical separation strip (stone piers, fences, green space, etc.) between the two directions of traffic or a double yellow line marking on the road surface.
i) Single-lane road: A road without a physical separation strip. 2

4.1.2 Node information
Node information includes intersection type, intersection sign, connecting road information, and traffic restrictions. 4.1.2.1 Intersection categories
There are three types of intersections: ordinary intersections, exits, and toll booths. 4.1.2.2 Intersection signs
According to the size and complexity of the intersection, the intersection should be divided into simple intersections (Figure 3) and compound intersections (Figure 4). All nodes are divided into the following categories according to the intersection signs: a) Simple intersection nodes:
-Record the relevant information of the intersection. Any point in the compound intersection can be used as the main point; b) Compound intersection main point-
) Compound intersection sub-points do not record intersection information and exist to correctly represent road information. N1
Figure 3 Simple intersection
4.1.2.3 Connecting road information
Record the signs of all roads directly connected to the intersection node. 4.1.2.4 Traffic restrictions
Figure 4 Compound intersection
-Main point; N2, N3, N4-Sub-points. Notes on each point: The line between N1—
is the line segment within the intersection and belongs to the composite intersection. Traffic restriction information at the intersection must include time limit information and prohibition information. 4.2 Background information
The background information should at least include the boundaries, railways, water systems, and green spaces within the scope displayed on the electronic map. It is recommended to display the elements with different levels of detail according to the map display level.
