Aeromagnetic anomaly data constitute one of the most important achievements in aeromagnetic work. It is the qualitative analysis of obtained aeromagnetic data via evaluation and interpretation. In order to meet the need of cartographic representation of final production map compiled by researchers in specific project, cartographers need to render the same data several times via different attributes. An Oracle database must be built as the unified storage and management platform so that the airborne geophysical data and information service can be provided efficiently. The authors investigated the mapping requirement of aeromagnetic anomaly and, in combination with management of Oracle database, constructed an auto-renderring model for aeromagnetic anomaly data. Then the authors implemented secondary development of auto-renderring workflow using C# language based on ArcEngine. Tests based on database data have validated that the results meet the standards. Now standardized API interfaces can be provided for other software development.
