I3S to S3M
Usage Instructions
This tool supports converting I3S 1.2-1.3 data that complies with OGC community standards and I3S 1.7-2.1 data conforming to the open-source community GitHub specifications into S3M tile data. Currently supported source data types include: oblique photogrammetry 3D models, BIM, fine city models, white-box building models, point cloud data, and point-attached models.
Parameter Descriptions
| Parameter Name | Parameter Description | Parameter Type |
|---|---|---|
| I3S File | Input source I3S file. Supported formats include *.slpk and *.gz. Among them, *.gz is the .json.gz file inside the folder extracted from \.slpk. | String |
| Tile Name: (Optional) |
Set the name of the result tile data. If not set, the source data name will be used as the result tile name. | String |
| Storage Path: | Set the storage path for the result tile data. | String |
| S3M Version: (Optional) |
Set the version of the result S3M tile data. Options include S3M 3.01 and S3M 3.0. | S3MVersion |
| Thread Count: (Optional) |
Set the number of threads allocated for this operation. When the thread count is 0, it means the number of threads equals the maximum number of cores of the current computer. | Integer |
| Target Coordinate System (Optional) |
Set the coordinate system of the result tile data by entering the EPSG code or a coordinate system file. Combined with the conversion method and projection conversion parameters, coordinate transformation of the data can be achieved. When the EPSG code is set to 0, no coordinate transformation will be performed, and the source coordinate system will be retained. Coordinate system files only support *.prj and *.xml files generated by iDesktopX functions such as Export Coordinate System. |
String |
| Conversion Method (Optional) |
Select the data coordinate system conversion method via the dropdown menu. Options include: 1. Geocentric Translation (3-para): Suitable for three-parameter coordinate transformation based on the geocenter. 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): Seven-parameter conversion method based on the geocenter. 6. Bursa-Wolf (7-para): A commonly used seven-parameter conversion method. 7. Molodensky-Badekas (10-para): A ten-parameter spatial coordinate transformation model. 8. China_3D_7P (7-para): Used for conversion between different coordinate systems and the 2000 National Geodetic Coordinate System (CGC2000). Suitable for control point coordinate conversion between geodetic coordinate systems at national and provincial levels with 3° or larger ellipsoidal reference differences. The conversion 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 earth ellipsoids corresponding to the two geodetic coordinate systems. |
CoordSysTransMethod |
| Projection Conversion Parameters (Optional) |
Set the parameters for the projection conversion of the data, including scale difference, rotation angle, offset, rotation origin, etc. Specific parameter values are specified by the Projection Conversion Parameters tool. | CoordSysTransParameter |
