Usage Instructions
The Grid Encoding Setting tool is used to set the dataset and corresponding attribute field names for storing the location code (or coordinate code) and elevation code generated after GeoSOT spatial subdivision or TaiGe grid subdivision. After the operation, a dataset recording the 3D grid codes will be generated in the specified path.
GeoSOT spatial subdivision divides the space where the data is located in three directions: longitude, latitude, and geodetic height, and assigns corresponding quaternary 2D grid codes and height domain codes to the subdivided 3D grid cells. For detailed subdivision and encoding methods, refer to the "Geospatial Grid Encoding Rules" (GB/T 40087-2021). Through this tool, the 2D grid code and height domain code will be recorded in specified attribute fields, such as QRCode and HCode.
TaiGe spatial subdivision divides the 3D space of a specified range into a set of continuous, seamless, and non-overlapping multi-level spatial units. The subdivided 3D spatial grids will be assigned grid codes. Through this tool, the grid code will be recorded in a specified attribute field, such as QRCode.
This tool is typically used in conjunction with the Build GeoSOT Grid Tiles (Model), Build GeoSOT Grid Tiles (DEM), Build GeoSOT Grid Tiles (Oblique Photogrammetry Model), Build GeoSOT Grid Tiles (TIN), Build TaiGe Grid Tiles (Model), Build TaiGe Grid Tiles (DEM), Build TaiGe Grid Tiles (Oblique Photogrammetry Model), or Build TaiGe Grid Tiles (TIN) tools.
Parameter Descriptions
| Parameter Name | Parameter Description | Parameter Type |
|---|---|---|
| Data Source Connection Info | Set the data source for storing the 3D grid code results. Note: This data source must not be the same as the data source containing the dataset to be spatially subdivided, otherwise the operation may fail. | String |
| Result Dataset Name (Optional) |
Set the name of the result dataset for storing 3D grid codes. The default value is SpatialCode. | String |
| Code Field Name (Optional) |
Set the name of the attribute field for storing the location code (or coordinate code) in the result dataset. The default value is QRCode.Note: The name must not contain special characters (~!@#$%^&*()-_=+|[{}];:,<.>/?). | String |
| Elevation Code Field Name (Optional) |
Set the name of the attribute field for storing the elevation code in the result dataset. The default value is HCode.Note: The name must not contain special characters (~!@#$%^&*()-_=+|[{}];:,<.>/?). | String |
