Introduction
Basic geographic information is an important basic and strategic information resource in the construction of national information, and it is the unified basis of geographical elements.
And space carrier, mainly including digital orthophoto data, terrain feature data, digital elevation model data, topographic map data.
National economic construction, national defense construction and rapid social development, the basic geographic information data of the normative, integrity, current situation put forward
Urgent requirement. This standard for the provinces, autonomous regions and municipalities 1. 10000 basic geographic information status, taking into account the production, building, more
New and distributed service requirements, the 1. 10000 terrain factor data are co-ordinated and maintained with other national scale terrain elements
According to the convergence, in order to achieve the national series of basic geographical information linkage update and collaborative services to lay the foundation.
Basic geographic information
Specification for terrain factor data
1 Scope

3 data description
Basic Geographic Information Terrain feature data is a vector dataset that expresses geographic information elements in terms of points, lines, and faces. The point element is represented as one
Coordinate elements and corresponding attribute values; the line elements are represented as a series of coordinate tuples and corresponding attribute values; the surface elements are represented by the first and the next
A string of coordinate tuples and corresponding attribute values.
1. 10000 terrain factor data is the main component of provincial basic geographic information, including positioning basis, water system, residential area and
Facilities, transportation, pipelines, realms and political areas, topography, vegetation and soil, toponymic 9 categories, widely used in the provincial economic construction and social development
etc.
4 data composition
1. 10000 Basic Geographic Information Terrain feature data consists of vector data and metadata.
a) vector data storage 9 categories of geographic information elements of the spatial coordinates, attribute information and the relationship between;
b) Metadata records A description of the vector data.
5 data requirements
Basic Mathematics
5.1.1 plane basis
Using the.2000 national geodetic coordinate system.
5.1.2 Elevation datum
Using the 1985 National Elevation Benchmark.
