Feature Description
Performs GeoSOT-based two-dimensional grid encoding on a dataset. Namely, after partitioning the Earth's space in the longitude and latitude directions based on GeoSOT, the grid cells on the Earth's surface are assigned corresponding quaternary two-dimensional grid codes. For detailed partitioning and encoding methods, refer to "Earth Space Grid Encoding Rules_GB_T 40087-2021".
Parameter description
| Parameter Name | Default Value | Parameter Interpretation | Parameter Type |
|---|---|---|---|
| Source Dataset | The vector dataset to be encoded. Supports point, line, region, 3D point, 3D line, 3D region, and model dataset types. Only datasets with a geographic coordinate system are supported. | DatasetVector | |
| Two-Dimensional Position Code Word Segment Name (Optional) | GeoSOT_2D_Code | Specifies the field name for storing the two-dimensional grid position code. This field must not already exist in the source data. | String |
Output Result
If the execution is successful, a new field "GeoSOT_2D_Code" will be added to the source dataset to store the quaternary two-dimensional grid position codes for the Earth's surface space.
The quaternary code of a GeoSOT grid starts with 'G', and the number of subsequent digits corresponds to the minimum grid partition level that completely encloses the geometry in the dataset.
Example:
Two-dimensional spatial code: G00131331010. This code indicates that the minimum grid partition level that completely encloses this geometry is level 11.
