I3S -> S3M
Usage Instructions
This tool supports converting I3S 1.2-1.3 data compliant with the OGC Community Standard and I3S 1.7-2.1 data compliant with the open-source GitHub specification into S3M tile data. Currently supported source data includes: Oblique Photogrammetry 3D Models, BIM, City Detailed Models, Architectural White Model Data, Point Cloud Data, and Point External Models.
Parameter Description
| Parameter Name | Parameter Description | Parameter Type |
|---|---|---|
| I3S File | Input the source I3S file. Supported data formats include *.slpk and *.gz. The *.gz file is the *.json.gz file within the decompressed *.slpk folder. | String |
| Tile Name: (Optional) |
Set the name of the resulting tile data. If not set, the source data name will be used as the resulting tile name. | String |
| Storage Path: | Set the storage path for the resulting tile data. | String |
| S3M Version: (Optional) |
Set the version of the resulting 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. A thread count of 0 indicates using the maximum number of cores available on the current computer. | Integer |
| Target Coordinate System (Optional) |
Set the coordinate system of the resulting tile data by inputting an EPSG code or a coordinate system file (*.prj or *.xml). Combined with the transformation method and projection transformation parameters, coordinate conversion of the data can be achieved. When the EPSG code is set to 0, no coordinate conversion will be performed, and the source coordinate system will be preserved. |
String |
| Transformation Method (Optional) |
Select the coordinate system transformation method via the dropdown menu. Options include: 1. Geocentric Translation (3-para): Suitable for geocentric three-parameter coordinate transformations. 2. Molodensky (3-para): The Molodensky three-parameter transformation method. 3. Abridged Molodensky (3-para): A three-parameter transformation method. 4. Position Vector (7-para): One type of seven-parameter transformation method. 5. Coordinate Frame (7-para): A geocentric seven-parameter transformation method. 6. Bursa-Wolf (7-para): A commonly used seven-parameter transformation method. 7. Molodensky-Badekas (10-para): A ten-parameter spatial coordinate transformation model. 8. China_3D_7P (7-para): Used for transformations between different coordinate systems and the China Geodetic Coordinate System 2000 (CGC2000). Suitable for control point coordinate transformations between national and provincial ellipsoid surface coordinate systems of 3 degrees and above under different geodetic datums. This method involves three translation parameters, three rotation parameters, and one scale factor, while also considering the differences in semi-major axis and flattening between the two reference ellipsoids associated with the two geodetic coordinate systems. |
CoordSysTransMethod |
| Projection Transformation Parameters (Optional) |
Set the parameters for the data's projection transformation, including scale factor, rotation angle, offset, rotation origin, etc. Specific parameter values are specified by the Projection Transformation Parameters tool. | CoordSysTransParameter |
