In the process of the survey, new technologies such as remote sensing, geographic information systems, big data, cloud computing and so on will be fully applied. For example, high-resolution remote sensing images will be utilized to assist in various types of surveys and assessments.

Using the spatial display and management functions of the geographic information system (GIS), it will carry out the unified management, analysis and evaluation of various types of spatial information and mapping; and it will build a cloud computing environment, construct a risk census big data management and processing system, and realize real-time on-line processing of the national survey and evaluation work.
