This standard was proposed by the National Mapping Geographic Information Bureau. This standard by the National Standardization Technical Committee on Geographical Information (SAC/TC230) centralized. This standard was drafted. Wuhan University, National Mapping Bureau of Surveying and Mapping Standardization Institute, the National Mapping Agency of Geodesy first team. The main drafters of this standard. Li Jiancheng, Shaw school year, SURVEYING, Yue Jianli, Jiang Weiping, Xi Qing Ji.IntroductionJuly 1, 2008, the state officially opened CGCS2000 geocentric coordinate system based on the coordinate system construction CGCS2000 city ride Standard mapping system urban infrastructure construction of key current. For ease of use, and should only be a city with the establishment of a national coordinate system Linked to the relative independence and unity of the city coordinate system, and shall be approved by the administrative department of surveying and mapping to create and use only after review and approval. In order to strengthen the urban measurements, specifications and guidance CGCS2000 geocentric coordinate system enabled China's urban construction coordinate system, Meet the needs of urban economic construction and social development, according to "People's Republic of China Surveying and Mapping Law" to develop this standard. Urban coordinate system construction specifications1 ScopeThis standard specifies the basic principles of urban coordinate system (urban plane coordinate system and elevation system) construction, building content, distribution network side Case, data processing, conversion between the coordinate system and so on. This standard applies to the construction of urban plane coordinate system and elevation systems.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated edition applies to this article Member. For undated references, the latest edition (including any amendments) applies to this document. GB/T 12897-2006 national one, second order leveling GB/T 18314-2009 Global Positioning System (GPS) measurement specification GB/T 23709 regional quasi-geoid refinement of the basic technical requirements CJJ8-99 city Measurement Specification CH/T2008-2005 global navigation satellite systems continuously operating reference station network specification3 Terms and definitionsThe following terms apply to this document. 3.1 Urban Coordinate System urbancoordinatesystem In order to meet the needs of urban construction, planning and construction of the establishment, including urban plane coordinate system and elevation systems. In order to reduce investment Movies deformation plane coordinate system established by the city tend to be relatively independent, but need to establish contact with the national coordinate system established by the Urban Elevation Consistent with the national legal system should elevation benchmarks. 3.2 Gauss plane coordinate system gaussplanecoordinatesystem Gauss - Kruger projection (Gauss projection for short) established by the plane rectangular coordinate system, the origin of each projection with the central meridian of the tape The intersection of line and the equator, x-axis positive direction for the central meridian north, y-axis positive direction to the east of the equator. 3.3 Height Compensation Plane elevationcompensatingsurface In order to avoid or reduce the length of the deformation, deformation based on Gauss projection length of the selected relative to the reference ellipsoid raise or lower the elevation reference Test surface, the length of the reference surface deformation is small or zero. 3.4 Urban framework network urbanframenetwork By a number of high-precision control points established by satellite positioning technology, has a three-dimensional reference maintain the city, passing precision geocentric sit Standard network and improve the control precision effect. 3.5 Urban basic network urbanal-aroundnetwork By urban framework on the basis of further network encryption configuration, control data for providing urban infrastructure to meet the measurement needs of local city ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 28584-2012_English be delivered?Answer: Upon your order, we will start to translate GB/T 28584-2012_English as soon as possible, and keep you informed of the progress.
