Projection Transformation

Because of the different ways to get geographic data, we often encounter the problem of different coordinate systems in Data Processing. At this time, in order to facilitate the processing, analysis, display and other operations between different Projected Coordinate System data, the Projection Transformation function provided by SuperMap can be used to perform projection transformation on the data. provides three Projection Transformation methods, Dataset Projection Transformation, Batch Projection Transformation and Coordinate Point Conversion. Users can select different ways to perform Projection Transformation according to their own needs. Among

The Dataset Projection Transformation is mainly applicable to the Projection Transformation of a single Dataset. The Result Data after the Projection Transformation is saved as a New Dataset without destroying the source data.
The Batch Projection Transformation is applicable to simultaneously converting multiple Dataset Projection Transformation into projections consistent with a Datasource, and saving the converted Dataset under the Datasource.
Coordinate Point Conversion is used to convert the Coordinate Transformation of a point into the coordinate in another coordinate system, and obtain the coordinate value of the point in the other coordinate system.
Model Transformation Parameter Calculation is used to select the control point coordinates of different coordinate systems such as 1954 Beijing Coordinate System and 1980 Xi'an Coordinate System with the control point coordinates of 2000 National Geodetic Coordinate System through coincidence points. Coordinate Transformation Parameters are obtained through operations such as Coordinate Transformation model and precision evaluation. The Transformation Parameters are used to realize the transformation of the data results to the national geodetic coordinate system 2000.
