Convert Model Data Projection

Usage Instructions

Supports the projection conversion of model datasets based on the target coordinate system. The converted model dataset is saved in the target datasource.

Parameter Descriptions

Parameter Name Parameter Description Parameter Type
Model Dataset Select the source model dataset Dataset
Model Vertex Conversion
(Optional)		 Set whether to perform vertex-by-vertex projection conversion on the model. When checked, the relative position relationships between model objects in the model dataset remain unchanged before and after conversion. It is recommended to keep it checked when the model dataset contains instance models (i.e., the number of model sub-object shares is greater than 1) and involves conversion from a geographic coordinate system to a projected coordinate system. Boolean
Target Projection Set the target coordinate system of the data.
In the iDesktopX processing automation interface, this parameter can be set through the target coordinate system dialog box.
On the iServer processing automation WebUI interface, this parameter requires entering the EPSG code corresponding to the coordinate system. For example, a parameter value of 4326 indicates the WGS 1984 geographic coordinate system.		 PrjCoordSys
Conversion Method:
(Optional)		 Set the method for projection conversion of the data, including:
1. Geocentric Translation (3-para): Suitable for three-parameter geocentric coordinate conversion.
2. Molodensky (3-para): Molodensky three-parameter conversion method.
3. Abridged Molodensky (3-para): Simplified three-parameter conversion method.
4. Position Vector (7-para): A type of seven-parameter conversion method.
5. Coordinate Frame (7-para): Seven-parameter geocentric conversion method.
6. Bursa-Wolf (7-para): A commonly used seven-parameter conversion method.
7. MolodenskyBadekas (10-para): A ten-parameter spatial coordinate conversion model.
8. China_3D_7P (7-para): Used for conversion between different coordinate systems and the China Geodetic Coordinate System 2000 (CGC2000). Applicable for national and provincial ellipsoid surfaces at 3 degrees or above for control point coordinate conversion between different earth ellipsoid datums. The method involves three translation parameters, three rotation parameters, and one scale parameter, while also considering the differences in the semi-major axis and flattening of the two corresponding earth ellipsoids.
9. China_2D_7P (7-para): Used for conversion between different coordinate systems and the China Geodetic Coordinate System 2000 (CGC2000). Applicable for national and provincial ellipsoid surfaces at 3 degrees or above for control point coordinate conversion between different earth ellipsoid datums. The method involves three translation parameters, three rotation parameters, and one scale parameter. For conversion from the Beijing 1954 coordinate system or Xi'an 1980 coordinate system to the CGC2000, it is recommended to use the two-dimensional seven-parameter conversion due to the low accuracy of geodetic heights in the two reference center systems.
10. China_2D_4D (4-para): A two-dimensional four-parameter conversion model for conversion between different coordinate systems and the China Geodetic Coordinate System 2000 (CGC2000). Applicable for local control point coordinate conversion within a range of 2 degrees or less at the provincial level and below. The model involves two translation parameters and one scale parameter.
11. PROJ4 Transmethod: Based on the PROJ4 third-party projection conversion tool, supports more projection conversion operations to meet the projection conversion needs of more overseas users. This projection conversion algorithm only supports conversions between projections with corresponding EPSG codes.		 CoordSysTransMethod
