Retain History
Usage Instructions
When performing a partial update on a local oblique photogrammetry 3D model, if you need to retain the original S3M tiles data that will be replaced (updated), you can use this tool to save it as OSGB data. The historical version data preserved in this way can effectively ensure the traceability of the update process and provide support for subsequent data management and version backtracking.
Parameter Descriptions
| Parameter Name | Parameter Description | Parameter Type |
|---|---|---|
| Storage Path: | Sets the storage path of the result data. | String |
| Center Point X (Optional) |
Sets the X coordinate value of the result data center point, whose unit corresponds to the coordinate system of the result data: degrees for geographic coordinate system, meters for projected or planar coordinate system. | Double |
| Center Point Y (Optional) |
Sets the Y coordinate value of the result data center point, whose unit corresponds to the coordinate system of the result data: degrees for geographic coordinate system, meters for projected or planar coordinate system. | Double |
| Center Point Z (Optional) |
Sets the Z coordinate value of the result data center point, whose unit corresponds to the coordinate system of the result data: degrees for geographic coordinate system, meters for projected or planar coordinate system. | Double |
| Target Coordinate System File (Optional) |
Sets the coordinate system of the result data by inputting a coordinate system file. Combined with the conversion method and projection conversion parameters, it can realize the coordinate conversion of the data. The coordinate system file only supports *.prj and *.xml files generated by functions such as iDesktopX Export Coordinate System. |
String |
| Conversion Method (Optional) |
Sets the conversion method to convert the result data to the target coordinate system. Options include: 1. Geocentric Translation (3-para): Suitable for geocentric three-parameter coordinate conversion. 2. Molodensky (3-para): Molodensky three-parameter conversion method. 3. Abridged Molodensky (3-para): Three-parameter conversion method. 4. Position Vector (7-para): A type of seven-parameter conversion method. 5. Coordinate Frame (7-para): Geocentric seven-parameter conversion method. 6. Bursa-Wolf (7-para): A commonly used seven-parameter conversion method. 7. Molodensky-Badekas (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 (CGCS2000). Suitable for control point coordinate conversion between geodetic coordinate systems under different earth ellipsoid datums at the national and provincial levels of ellipsoid surface of 3 degrees or more. The conversion method involves three translation parameters, three rotation parameters, and one scale change parameter, while also considering the differences in the semi-major axis and flattening of the two corresponding earth ellipsoids. |
CoordSysTransMethod |
| Projection Conversion Parameters (Optional) |
Sets the parameters for projection conversion of the data, including scale difference, rotation angle, offset, rotation origin, etc. The specific parameter values are specified by the Projection Conversion Parameters tool. | CoordSysTransParameter |
