Due to the diverse methods of acquiring geographic data, different coordinate systems often pose challenges during data processing. To facilitate operations such as processing, analysis, and display between datasets with different projected coordinate systems, SuperMap provides projection transformation capabilities. offers three projection methods: Reproject Dataset, Batch Reproject, and Transform Coordinates. Users can choose the appropriate method based on their requirements:

• Reproject Dataset applies to individual datasets. The result data will be saved as a new dataset without altering the original data.
• Batch Reproject enables simultaneous projection conversion of multiple datasets to match a target datasource's coordinate system, storing converted datasets within that datasource.
• Transform Coordinates performs coordinate transformation for specific points between different coordinate systems.
• Calculate Transformation Model Parameters obtains coordinate transformation parameters between systems like Beijing 1954 Coordinate System/Xi'an 1980 Coordinate System and China Geodetic Coordinate System 2000 (CGCS2000) through operations including coincident point selection, coordinate transformation modeling, and accuracy evaluation. These parameters enable conversion of spatial data to CGCS2000.
