Abstract： With the development of technology, surveying and mapping geographic information have transformed from traditional data resources into data elements, playing a "linking" role among various types of data and being particularly important for data governance. This paper focuses on geographic information element data, and analyzes its characteristics and problems. In the face of the situation that it is difficult to converge and manage, and the application quality and efficiency are low, based on the concept and idea of the data middle-platform, a system architecture for the fusion governance of geographic information elements oriented to the data middle-platform is designed, and a full-process practical method is proposed. Moreover, the processes and methods of the two key steps, namely data fusion and element materialization, are elaborated. The effective fusion and governance of geographic information elements plays an important role in constructing a digital China and promoting high-quality economic and social development.
Key words : geographic information element data; data middle-platform; element data fusion; element data materialization
