" This standard compared with GB/T 14395-1993, the main changes are as follows. --- Increasing the foreword, introduction, Appendices A and B. --- Adjust the terms and definitions of some items. removed the "city layout", "urban road classification", "Fast Road", "Main Trunk "," sub-distributors "," branch "," other road "," road "," neighborhood-level road "," Locations "and other terms; increase the" Geography Elements "," feature class "," feature instances "," urban roads "," municipal engineering pipeline "," location area "and other terms. --- Increase in the basic structure of urban geography elements encoded feature is determined by the geometry of the structure type code, feature class code, location area Field code and serial number feature instance combination. --- The code structure urban roads, road intersections, neighborhood, municipal engineering pipeline junction in the city unified basic geographic elements coded Within the framework of the structure. --- Adjust the standard layout structure. The Standard Appendix A, Appendix B is an informative annex. This standard is proposed and managed by China National Institute of Standardization. This standard drafting units. China National Institute of Standardization, Beijing Urban Planning and Design Institute, Beijing Geographic Information Center. The main drafters of this standard. Li Xiaolin, River Island, JIA Hai Yue, Zhang He, Chen Huang, Tong Wen will, Qiusu Wen. This standard was first published in 1993, this is the first revision.IntroductionGeographic feature on Earth is the expression of the position of the relevant real-world phenomena, urban geographic feature is a subset of geographic features. Urban land Natural geographic features such as mountains, rivers, and other waters, but more through artificial construction and reconstruction after formation, such as roads, neighbors and so on. Geographic features of the identification code for the modernization of urban management, planning and sustainable development of science has important practical significance. Geographic feature class a lot, the number of instances is also a great feature, so its coding must also be very complicated, it requires a certain standard Quasi-regulated guidance. To this end it is necessary to standardized coding Geographic feature. By standard geographic features can be all kinds of geographic coding Organizational elements in a unified scientific space positioning system, for easy retrieval, analysis and synthesis. This is also the first to establish Geographic Information System jobs. This standard coding structure Geographic feature gives a basic structure, and specific to urban roads, road intersections, Neighborhood, municipal engineering pipeline and other geographic features 4 real city encoding scheme. This standard is the first city as coding standard geographic features, although only for geographic features in the city roads, road intersections Mouth, neighborhood, municipal engineering pipeline, but in the overall framework of the standard also proposed for urban municipal area other geographic features coding Reference, reference. Appendix B is operational recommendations in this regard. Geographic features Encoding Rules Urban roads, road intersections, neighborhood, Municipal engineering pipeline1 ScopeThis standard specifies the elements of the main principles of urban geography and basic coding structure specifies the city roads, road intersections, neighborhood, Municipal Engineering pipeline encoding rules and code structure. This standard applies to the large, medium and small cities the preparation of urban roads, road intersections, neighborhood and municipal engineering pipeline and other geographic features Generation Code system, other geographic features can also refer to the use of coding.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 Expression and location on the planet associated with real-world phenomena. NOTE. geographic feature can have two forms. one is the feature class, the other is a feature instance. When the expression of only one meaning, it should be clear whether simply more Su refers to a class or feature instances. 2.2 Share describe the same attributes, operations, relationships and semantics of a set of features. 2.3 An object that implements the feature class. 2.4 City territory, formed the main differences between geographical elements geographic categories, by geographic area. These elements in the spatial distribution of significant Differences play a leading role in the formation of geographical features and evolution. NOTE. In this standard, coded means Geographic feature instances. 2.5 Cities for vehicles and pedestrians, with certain technical conditions of the road. 2.6 Two or more urban road intersection. 2.7 Or by the urban roads and other relatively stable Geographic features (such as rivers, railways, etc.) surrounded by a complete urban roads surrounded Lot. Note. Some of these elements and the neighborhood is divided into administrative boundaries formed. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 14395-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 14395-2009_English as soon as possible, and keep you informed of the progress.
