1 Characteristics of smart cities

Smart city = modernization+digital city, that is to say, with the development of the Internet and the Internet of Things, the essence is to use the modern technology of the Internet, and the essence cannot be separated from the development of basic materials. Through the combination of various technologies, the intelligent management and operation of cities can help people realize their ideal cities and promote the sustainable development of cities in the future. Smart cities are closely connected with the Internet of Things, and the development of smart cities depends on the development of the Internet, which is closely related to the Internet of Things. The development of cities is inseparable from the interaction between the Internet of Things and the Internet, so smart cities must be closely connected with the Internet of Things in order to achieve material balance and maintain the development of cities.

2 the main content of smart city construction

The essence of a smart city is to integrate urban information and then use it. Build a new urban life system with the concept of low carbon and environmental protection. So as to realize the people-oriented, rational use of resources, comprehensive and coordinated sustainable development strategy. The main content of smart city is to carry out convenient and simplified intelligent information processing in our life, speed up the pace of life and reflect the sense of science and technology in modern life. Therefore, we need to know more about how to enjoy the comfortable life experience brought by technology in smart cities. Therefore, it is necessary to lay a solid foundation, make spatial information intelligent, strengthen the comprehensive application of network technologies (cloud computing technology and sensor technology), realize system information management and intelligent city construction, and develop high-quality modern smart cities.

3 the significance of applying new surveying and mapping technology to build a modern smart city

3. 1 Provide basic information for the construction of smart cities.

According to relevant statistics, we can see that 80% of our information is related to personal spatial positioning. Therefore, in the process of building a smart city, survey is the most basic and important link, and the key information of survey is the main content of geographical position report. Under the intelligent information processing, the relevant data provided by the survey provide the main theoretical framework for building a smart city. With the emergence of modern high technology, the latest data measurement and processing system based on cloud computer and Internet of Things has become the foundation of building a smart city.

3.2 Provide perceptual information for the construction of smart cities

With the rapid development of modern science and technology in the new era, new geographic information collection technologies such as digital aerial photography, low-altitude photogrammetry system, tilt photography technology and high-resolution satellite remote sensing have been widely used in the construction of smart cities. Image acquisition can control smart cities with high precision and create conditions for visualization technology of urban geographic information. At the same time, it can compare surveying and mapping information and predict the changes of urban development more accurately.

3.3 is the application support of smart city construction.

Surveying and mapping information system with new security technology provides rich data guarantee for urban construction, and electronic information surveying and mapping gradually replaces modern traditional surveying and mapping technology. Especially in the establishment of global positioning system, it has higher accuracy and greater flexibility, which provides more data sources for remote sensing technology. Further strengthen the spatial capability analysis of geographic information system and the combined application of virtual reality. The organic combination of surveying and mapping information technology and global positioning system, as the application support of smart city, can quickly provide more accurate spatial information processing and a huge environmental renewal technology system.

3.4 Improve the intelligent degree of smart city construction

The visual characteristics of geographic information obtained by new surveying and mapping technology can more intuitively display the distribution of urban information spatial perception and any abnormal changes; The spatial analysis module of geographic information on the map plane, combined with the intuitive and concrete industry analysis model, shows the changing law, distribution and development in the spatial dimension, and provides more accurate and timely analysis results suitable for urban spatial location. In addition, the integration of internet technology and data mining technology with spatial data is helpful to improve the discovery and extraction of various information and the construction of spatial smart cities.

4. Specific application of new surveying and mapping technology in smart city construction.

The development of smart cities needs the support of new technologies. While science and technology are developing, they also promote the all-round development of new surveying and mapping technologies. In the construction of smart cities, it is necessary to give full play to the advantages of new technologies in surveying and mapping industry and obtain comprehensive spatio-temporal data resources in time. Provide necessary technical support services for other construction projects. First of all, combined with the advantages of cloud computing, the Internet and the Internet of Things are comprehensively utilized, and the latest information technology is adopted for surveying and mapping and map shooting. Plane photography surveying and mapping technology has broad application prospects in promoting the construction of urban intelligent special system, promoting urban economic culture, environmental coordination and sustainable development.

4. 1 Construction of spatio-temporal information cloud platform

First, we need to establish a system that can share information and realize resources, share geographic information anytime and anywhere, and realize information visualization, address matching and environmental coordination. In order to meet the requirements of urban smart development, it is necessary to build a spatio-temporal information cloud platform based on big data. Having a complete spatial information storage and application platform can play a greater role in the modeling, storage and processing of geographic information systems, the use of cloud computing, and the realization of cloud platforms. The application of various location-related applications in smart cities is based on the spatio-temporal information cloud platform, providing services such as positioning, data processing, construction, processing and analysis of the spatio-temporal information cloud platform for smart cities, realizing data sharing, exchange, integration and information acquisition, data collection, editing, storage and integrated job release, providing public service data for all urban departments, comprehensively coordinating urban management services, integrating various information resources, and effectively coordinating urban security in different places.

4.2 Providing spatial data

4.2. 1 digital aerial digital photography With the development of CCD sensor technology, China has gradually developed aerial digital cameras with independent intellectual property rights, such as TOPdc and Swdc, and conducted many scientific research experiments. The sensor direction of linear array represents the product AdS40, and the sensor direction based on area array represents dMc, ucd, etc. Aerial digital sensor has become the main equipment for obtaining high-resolution images in China, and it is also the key to building an intelligent large-scale digital ground model of the city, and the main data source of digital orthophoto and DLG digital elevation model.
