Single and combined properties. For attributes such as single, combined, tribyte, and sub-attributes, they can be divided into simple and complex properties. A property can have one component, a property can have multiple components, and a complex property can also be a composite property. Therefore, a complex property can be a composite property, and a complex property can be a composite property. Therefore, the properties of a complex property can be a composite property, and the properties of a complex property can be a composite property. Therefore, the properties of a complex property can be a composite property, and the properties of a complex property can be a composite property. Therefore, the properties of a complex property can be a composite property, and the properties of a complex property can be a composite property. Therefore, the properties of a complex property can be a composite property, and the properties of a complex property can be a composite property. Therefore, the properties of a complex property can be a composite property, and the properties of a complex property can be a composite property. Therefore, the properties of a complex property can be a composite property, and the properties of a complex property can be a composite property. Therefore, the properties of a complex property can be a composite property, and the properties of a complex property can be a composite property. ReferaneinTausre refers to linear objects (such as roads, resources and water systems) that are related to the network concept model. It is a set of independent entities with no explicit topological relationship between them. For each entity, a one-dimensional image system can be used. The properties of the entity can be defined by the properties of the entity. 3.21

The nature, characteristics and relationship of all elements are applicable to the main elements. The frequency following (rules) and manoeure are defined separately to make the ten elements suitable for the relevant records. In order to meet the requirements of a certain avoidance rule, a road element is defined. A connection point and a near element are formed by a layer of layers.

5 5.1 Data Content The main contents of this standard are based on GB/T19711-2005 TKoNK standard, which focuses on the main themes of "road construction and vehicle reduction" and related important topics, and stipulates the internal safety of the treatment, including the information of the two important elements and the (traffic) relationship information. Due to the characteristics of the main elements, the user's definition and the user's demand, this standard shall not be used too much in actual application. According to their spatial distribution characteristics and their importance in production and use, these key points can be divided into traffic network category, display background category, and information category. The traffic network category is composed of the elements of road structure and traffic shortage, and is the most important component of semi-recovery geography, including roads and vehicles, public transportation facilities, road stations, and other essential elements. The background data is mainly used for investigation and control, including administrative services, naming of regional land use issues, and historical data.
5.2 Spatial data structure
According to this standard, the spatial data structure of the collected data elements shall comply with the provisions of GB/T191-2005. GB/T191-2005 defines three topologies: complete topology, non-complex topology and non-complex topology. In the complete topology, the 0-dimensional and 2-dimensional elements are points and edges, which form a plane. The 2-dimensional elements are defined by (e), which is the basic building block of the plane. The relationship between them is shown in Figure 2.
In addition to the definition of
2 completely,
is generated by the principle of
GB/T23288—2QDB
The main concept of the continuous folding is that the building blocks are points and edges, which constitute a non-planar graph. That is, in reality, two elements are in different layers (when the two roads intersect, they must be on the same level), and the intersection of these elements is defined by points, which must be used to form the boundary of this element (Bonlay>. In non-explicit drawing, the building blocks of 12 elements are points, polygons, and their synonyms are only related by coordinate values.
In the number Belt sound processing, the basic requirements will be the quality of the product topology is also subject to high-speed and practical needs to be completely disassembled and connected
5.3 Coordinate requirements
This standard does not make specific provisions for the coordinate system of the entire disassembled set, and the producer shall follow the relevant provisions of the network and the number of indicators to make the producer's own requirements,
5.4 Reserved organization
5.4.1 Spatial division of garbage collection
This standard does not make specific provisions for the necessary division of the space of the collection, and the producer can determine the space division method based on the lack of data channels. For example, the administrative area of ​​the city traffic management area is divided into a topographic map to organize the teaching belt type, and the whole car should be taken into account. The characteristics of the state should be used to avoid the spatial division of the state administrative area.
5. 4.2 Double data nesting is to divide the data into different layers according to the data. In some cases, the data can be collected and the theme can be changed to the two categories. For example, the theme of the page includes route elements, connection points, contact points, area boundaries, address areas, etc. There are many sub-categories for group traffic, which can be stored in a map or stored in one go. 5.4.3 The data must be stored in a separate file or in a separate document. The partition identifier and the surrounding layer identifier must be separated or constructed in a separate file. The partition identifier can be an administrative division, a city division, or a management division number (when the data is stored in a separate file), or a national standard map number (when the division is valid, the map can be used to adjust the division effect). The main function of the old method can be customized, and the data can be used to generate a customized result.
