Abstract: While Hunan's new fundamental surveying and mapping system is progressing steadily, the transformation and database construction of fundamental geo-entities on the provincial level is one of the important tasks. Under the premise of following the relevant technical standards of the Ministry of Natural Resources, a set of standards and specifications for the classification of fundamental geo-entities applicable to Hunan province has been established. By integrating the 1∶10 000 fundamental geographical information and the annual changes of the third national land resource survey and other multi-source data, taking the geo-entity codes as the unified identifier, the research proposes a knowledge-rule based multi-source data fusion and transformation method for provincial geo-entities after making full use of the existing stock data, and realizing the standardization transformation of provincial fundamental geo-entity data, so as to avoid the waste of resources in repeated production, and greatly improve the production efficiency of fundamental geo-entities. Therefore, it is conducive to the promotion and application of fundamental geo-entities in the industry.
