Topology Checking
Usage Instruction
Perform topology error checking on datasets. Topology checking is to check out the objects that do not conform to the topology rules in the point, line and surface datasets themselves and between different types of datasets, and save the checking results to the dataset (i.e. point, line and surface dataset). It is mainly used for data editing and topology analysis pre-processing.
Parameter Description
Parameter Name | Default Value | Parameter Definition | Parameter Type |
---|---|---|---|
Source Datasets | The specified source dataset for polygon topology processing can only be a line dataset or a network dataset. | DatasetVector | |
Reference Dataset (Optional) |
The reference dataset specified for checking. If the topology rule used does not require a reference dataset, set to null. | DatasetVector | |
Topology Rules | Topology Rules | TopologyRule | |
Tolerance | 0.0 | The tolerance control required for the specified processing. The unit is the same as the unit of the data set for topology preprocessing. The range of values is greater than or equal to 0. Less than 0 will throw an exception. | Double |
Inspected area (Optional) |
The specified area to be checked, if the area is null, the entire topology dataset is checked by default, otherwise the topology is checked for the set area. | GeoRegion | |
Datasource where the result dataset is located | The datasource where the specified result dataset is located | Datasource | |
Name of the result dataset | Name of the specified result dataset | String |
Output Result
Parameter Name | Parameter Definition | Parameter Type |
---|---|---|
Repair Dataset | After performing the repair of topology errors, the repaired dataset is returned, which is the source dataset. | DatasetVector |
Checking Datasets | The topology error dataset checked out. | DatasetVector |
