On February 18, 2019, the General Office of the Ministry of Natural Resources released the "Technical Outline for the Construction of Smart City Space-Time Big Data Platform (2019 Version)". This "Technical Outline" was born after being revised and improved on the basis of "Technical Outline of Cloud Platform Construction" released in September 2017.
Compared with the 2017 version of the "Technical Outline", the title of the 2019 version has changed from "Technical Outline of Smart City Space-Time Big Data and Cloud Platform Construction" to "Technical Outline of Smart City Space-Time Big Data Platform Construction". Highlighted the focus of the latest version of the "Technical Outline"-spatio-temporal big data platform. At the same time, the Ministry of Natural Resources also emphasized in the notice that "the spatio-temporal big data platform is the basic support for the construction and operation of smart cities. The smart-city spatio-temporal big data platform is an important part of the digital China spatio-temporal information database and an important task for the transformation and upgrading of basic surveying and mapping . "
The importance of surveying and mapping work has also been greatly stressed in the new edition; guiding the natural resources authorities of various regions to carry out the construction and application of smart city spatio-temporal big data platforms has now become one of the important tasks of the Ministry of Natural Resources; "Cloud Platform" is the part that changes the most in the content, for example: in the classification of cloud platforms, it is changed from the previous version of "generalized platform", "specialized platform" and "personalized platform" (according to the classification of application objects) . There are two types of "desktop platform" and "mobile platform" (according to the classification of application scenarios); in addition, natural management service systems are also added to typical applications.
Future Science City Smart City Pilot Zone Construction Project
A picture of spatio-temporal information intelligent support platform project
Digsur undertook the construction project of the future Smart City Pilot Zone of Science City-a project of intelligent support platform for one map of space-time information. The intelligent support platform for one map of spatio-temporal information is the construction of a digital platform for spatial data information and thematic geographic information resources within 10 square kilometers of the first phase of the future Science City.
Main technologies applied
Data collection is based on high-precision aviation and flight data to extract multiple types of data. Inject the acquired data of various vectors, images, elevation models, geographical entities, geographical names, addresses, 3D models, tilt photogrammetry, etc. into the time, space and attribute "three domains" logo.
The system construction is based on the concept of sharing and exchange. It is mainly divided into spatio-temporal big data management, spatio-temporal information cloud platform, urban application, and 3DGIS + BIM data processing and information management platform. In order to meet the needs of massive, multi-type data production and management and frequent data updates, we provide one-stop tools for spatio-temporal data storage, mapping, release and integrated management.
Collect the basic geographic information of all the elements in the future Science City, and greatly improve the integrity and content of the basic geographic elements. Establish a data sharing and exchange platform to achieve unified management and synchronous exchange of spatio-temporal information resources, support future Science City application management in urban operation, planning and construction, etc., and enhance future science city urban public basic spatio-temporal information management and service capabilities.
