Abstract： [Purposes]To address the significant differences indata structures，feature classification，and attribute definition between city and county-level basic geographic information databasesand the provincial-level （based on Hunan Province）database，caused by the adoption of different standards during their production，management，and application processes，this study develops a key technology and method for intelligent transformation of basic geographic databases to effctively resolve the inconsistenciesbetween the city/county-level and provincial-level databases.[Methods]A geographic database intelligent transformation solution was developed based on the domestically developed and independently controllable SME （Southern Data Sorting and Processing Engine）.Auxiliary transformation tools based on the ArcGIS and CAD platforms were developed. The proposed approach was verified by selecting project cases.[Findings] The results show that with this method，the project was completed 2O daysahead of schedule.No element omissions or losses occurred during the transformation process.The output is accurate and reliable，fuly complying with the relevant technical specifications.[Conclusions] This transformation method demonstrates both feasibility and practical value，providing significant reference for subsequent research.
