Based on the extended application of big data technology in the planning industry in recent years, the institute has carried out a series of explorations and studies and accumulated certain achievements and experiences. By sorting out the existing research results, key emphases in work can be roughly summarized into four aspects: data standard setting, model innovation and application, multi-source data analysis, and the refined planning and design relying on big data. It can be said that the big data analysis application system in the institute has been formed initially.

Overview of Data Application Module

A brief introduction is given below on the relevant research results based on the above-mentioned four aspects.

1. Formulation according to standards

The detailed regulations shall be conducted for the standards of processes such as the submission for approval, reporting for filing, information-based warehouse input of the statutory planning of urban and rural areas, so as to comply with the historical trend of urban planning informatization, and respond to the national policy of "strive to the end as guided in the blueprint"; in order to meet the construction needs of "Guangdong Wisdom Planning Information Services Platform", it provides the data support to promote the urban-rural planning and management system reform and the linkage of provinces and cities. It has formed seven standard documents, which are as shown in Figure 1,

including Specification for Submission for Approval (Filing) of Statutory Urban-rural Planning Results in Guangdong Province (including urban master plan, recent urban construction planning, detailed planning for urban control) and Data Standard of Statutory Urban-rural Planning Results in Guangdong Province (including urban master plan, recent urban construction planning, detailed planning for urban control) and Classification Code and Symbol Style Standards for Statutory Urban and Rural Planning Elements of Guangdong Province.

        It is featured with three orientations

        (1) Oriented at the planning information, all the data are guaranteed with the standards of "all covered without exception";

        (2) Oriented at the urban and rural planning reform, the key data is guaranteed with the standards of "aiming at well managing large enterprises while adopting more flexible policies toward small ones";

        (3) Oriented at the provincial, ministerial and municipal three-level three linkage, the input efficiency is guaranteed with "template + software".

2. Build high plasticity model to meet the promotion needs

The "Big Data + Planning" is the new direction for planning and development. It is the top priority for the combination of dual disciplines as how to effectively utilize the big data and achieve the standardization and flow pattern of the processes such as data acquisition, data storage, data analysis and data visualization.

        In this project, by reserving the model parameters interface, it ensures that the model data can be replaced and the analysis parameters can be fine-tuned, so that the model can be applied to different planning and site selection projects, including urban facilities location, hospital location, fire system site selection, etc. The standardized model analysis process can further improve planning efficiency, increase planning accuracy, save planning time and manpower, so as to better save planning costs, and reflect the humanistic and intellectual characteristics of planning as shown in Figure 2.

3. Multi-source data analysis

Through the integration of multi-source data such as environment, municipal administration, spatial status, planning plan, POI data, real-time heat distribution of population, real-time traffic flow data, real-time sign-in status of network users and so on, the analyses are conducted for eco- environment, wind environment, water environment, residents living situation and residents travel modes and preferences, the flow of passengers and goods and so on, so as to provide data support for the preparation of a more reasonable planning program, which is as shown in Figure 3.

4. Refined planning and design relying on big data
