Background technology
With continuing to develop for city, the urban issues such as population expansion, traffic jam, environmental pollution, energy shortage is continuous
Increase, smart city concept is arisen at the historic moment.Smart city is the urban development theory according to science, utilizes generation information skill
Art, on the basis of ubiquitous information complete perception and interconnection, realizes and is seamlessly connected between people, thing, city function system with cooperateing with
The intelligence of linkage is from perception, adaptive, self-optimizing, so that many to the people's livelihood, environmental protection, public safety, city function, commercial activity etc.
Kind of city demand makes intelligent response, formed the inner system dynamics that possess sustainable development safely, conveniently, efficiently, green
Urban morphology.
At this stage, with the fast development that China smart city is built, Urban Data holds amount and type and explosion type increasing is presented
Long, data source is rich and varied, isomeric data characteristic remarkable, especially substantial amounts of stream medium data（As traffic video, security are supervised
The data such as control) and real-time dynamic city real-time observed data（Such as meteorological, environmental protection, positioning sensing data）Emerge in large numbers, effectively
These data of management and use turn into a major challenge.Simultaneously as China's city operations and management informationization be one progressively
Perfect process, for different application fields in the scattered system implemented of different times, due in running environment, data base set
System, method of service, information coding rule, operation flow perform different standards in terms of defining, system can not be interconnected, believed
Breath can not be shared extensively.When in face of specific city is cross-cutting, many data synergistic applications when, Urban Data resource show it is not only many but also
Few situation：The running status that city possesses the archive data existed in a variety of ways of the big scale of construction and continually produced is real

It is SVG and WEB CGM isovector forms）；WFS supports the insertion to geographic element, updates, and deletes, retrieval and discovery service；
WCS provides the space lattice figure layer for containing geographical location information or attribute, rather than static map access.WMTS pairs
Slice of data access stencil is answered, such as realizes that world figure stepless zooming operation is accomplished by calling WMTS to service.Microsoft provides
Internet Information Services（IIS, Internet Information Service）, sent out by setting up the form of website
There is provided to local static data, such as multi-medium data, such as video, picture, the quick access of text for cloth local resource.These nets
Network service be it is single presence or certain it is several exist together, one or several kinds of data modes can only be confined in the access,
Lack for the unified discovery of diversiform data, access.
At the shared aspect of real-time observed data, Open Geospatial Consortium in 2006（OGC）SOS is issued（Sensor is seen
Survey service）1.0 versions, Open Geospatial Consortium in 2012 has issued the versions of SOS 2.0.SOS is noted there is provided management of sensor
The API of volume and discovery sensor data, is serviced by this, and client can obtain one or more with SOS standard interface
The observation data of sensor.Sensor observation service is suitable for the data of hourly observation attribute-observation form, does not support other
Data type.
