1.Application value of big data in geographic information system

1.1 Improve the completeness and accuracy of geographic information data

At present, big data has penetrated into various industries and functional areas, providing important production factors for their business development and becoming an indispensable part of various industries and fields. Geographic information system is no exception. The application of big data can bring new opportunities for the development of geographic information system. From the perspective of the development of GIS, it is closely connected with the rapidly developing data center and the Internet. The establishment of a modern information technology system based on GIS is just around the corner, and the entire industry has huge development potential. When big data is applied in geographic information system, the data collection ability, collection speed, analysis ability and storage function will be significantly improved, which will greatly reduce the work pressure and workload of staff, and further improve the work efficiency and quality. Compared with the previous information technology, big data technology has more obvious application advantages. It can obtain comprehensive, complete and detailed data information and provide real-time and long-term value information for multiple industries and practical applications.

In addition, the development of modern geographic information system also needs the strong support of modern surveying and mapping technology. The application of big data technology can ensure the accuracy and efficiency of surveying and mapping engineering data information, thus providing impetus for the sustainable development of geographic information system. The application of big data in geographic information system can continuously expand the application scope of big data, master geographic information at the macro level, and summarize and analyze the change characteristics and future development trend of geographic information system according to the change of big data. The multiple integrated data and related information with high reliability and accuracy provided by big data can provide reliable support for relevant decision-making of geographic information system, effectively verify geographic information and macro information, and promote systematic, refined and standardized management of geographic information system.

1.2 Provide data support and technical support for enterprise transformation and development

If any industry wants to become bigger and stronger, it needs to keep pace with the development of the times and carry out timely reform and innovation. However, reform and innovation cannot be separated from the support of accurate information and scientific basis. If the enterprise blindly carries out the reform without mastering the scientific basis, it will inevitably face failure, and may even bring destructive damage, which will make the enterprise depressed.

At present, China has entered the era of big data. Massive amounts of data are occurring every day and are constantly changing. Geographic information enterprises can comprehensively analyze big data, obtain more intelligent, in-depth, valuable information that is conducive to the transformation and development of enterprises, change their business scope, use relevant advanced technologies to promote actual operation and development, and ensure that enterprises can stand firm in the wave of reform and development, In a leading position, the company successfully completed its transformation, so as to better provide services for social development and promote high-quality economic development. In a word, all industries and enterprises need to correctly understand the value of geographic information and big data, improve the efficiency of collecting and sharing geographic space and related information, integrate them into their own business development, and provide data support and technical support for enterprise transformation and development while improving the value of big data.

2.Specific application of big data in geographic information system

2.1 Efficient storage of GIS data

With the comprehensive development of information science and technology, it has promoted the rapid and sustainable development of China's geographic information industry to a certain extent, keeping it in a relatively stable growth trend. However, in the modern geographic information industry, there are still many problems, such as information security protection, information management, information sharing, and a large number of duplicate geographic information spatial data. In order to effectively solve these problems, it is necessary to apply big data to geographic information systems, store geographic information system data efficiently, and effectively ensure the stable development of geographic information industry.

Of course, we also need to increase research efforts, continue to research, develop and innovate big data space storage technology, use distributed storage to replace centralized storage, and use cheaper machines to replace expensive machines, thus greatly reducing the cost of mass storage. As far as the current situation is concerned, information technology is widely used in everyone's life, work and study. With the mature development of modern information technology, the cost of computer related equipment has decreased significantly, and the economic cost of computer storage equipment has also decreased.

2.2 Support diversified and diverse information types

At present, the geographic information system in the geographic information industry has a very significant feature, which is the diversity and diversity of data sources, which also makes the data stored in the geographic information system develop towards a diversified type. Different industries and fields have different requirements for information use. If the amount of data information used is small, you can use manual data integration and data information conversion to meet the actual use needs. This not only can achieve the unification and standardization of data structure, but also can ensure that different data types and traditional information relationship types maintain a unified pace in storage standards.

If a large amount of data information is processed in the geographic information system, it is necessary to adopt multiple storage methods of unstructured information, or data information with different sources, channels and structural forms should be classified and stored, so as to ensure that the use experience needs of various users can be effectively met. The realization of the above content requires the support of big data technology to improve the information processing and storage functions of geographic information system to support diversified information types.

Conclusion

To sum up, big data has a crucial application value in geographic information systems. It can not only improve the efficiency of data information processing, improve the completeness and accuracy of data information, expand the data storage capacity, but also provide data support to facilitate the smooth completion of the transformation of enterprises.

It is also the mainstream direction of the development of the geographic information industry. However, as far as the application of big data in GIS is concerned, although some progress has been made, the expected ideal stage has not yet been reached. Therefore, we have a deep understanding of the importance and necessity of big data. In practical development, we need to accelerate the integration and coordinated development of big data and geographic information system, optimize and upgrade geographic information system, provide high-quality services from all directions and angles, and promote the long-term development of geographic information industry.
