Point On Boundary
ផ្ទៀងផ្ទាត់ថាចំណុចព្រំដែនស្ថិតនៅលើព្រំដែនក្បាលដីរបស់វាពិតប្រាកដ ដោយប្រើ topology geodatabase និងវិធាន “point must be covered by boundary”។

ទិដ្ឋភាពទូទៅ
A boundary point that has drifted off the polygon edge — by a fraction of a millimetre or by metres — breaks the correspondence between the coordinate listing and the mapped parcel. This tool finds those points.
ការប្រើប្រាស់
- The tool works in two modes, selected with New Topology?:
- Checked — A new topology is created for the check. Input Point Feature and Input Boundary Feature are used to identify the layers.
- Unchecked — An existing topology is reused. Supply Input Topology.
- Every parameter is marked optional because which ones are needed depends on the mode. In practice:
| Mode | Required in practice |
|---|---|
| New topology | Input Point Feature, Input Boundary Feature |
| Existing topology | Input Topology |
- Input Point Feature accepts point layers only; Input Boundary Feature accepts polygon layers only.
- Both layers must live in the same feature dataset as the topology.
- The rule tests coincidence within the topology's cluster tolerance. A point that looks coincident on screen can still fail if it is off by more than that tolerance — zoom to the reported error before assuming it is a false positive.

|---|---|---|
| New Topology?ជម្រើស | Boolean | Selects the mode.
|
| Input Topologyជម្រើស | Topology | The existing geodatabase topology to validate. Used when New Topology? is unchecked. |
| Input Point Featureជម្រើស | Feature Layer | The boundary point layer to test. Point geometry only. Used when New Topology? is checked. |
| Input Boundary Featureជម្រើស | Feature Layer | The parcel polygon layer whose boundary the points must lie on. Polygon geometry only. Used when New Topology? is checked. |
របៀបប្រើ
Create a new topology for the check
- Confirm the point and polygon layers are in the same feature dataset.
- On the KGA Toolbox tab, in the Geoprocessing group, open the Topology gallery and click Point On Boundary.
- Check New Topology?.
- Set Input Point Feature to the boundary point layer.
- Set Input Boundary Feature to the parcel polygon layer.
- Click Run, then review the reported errors in the error inspector.
Reuse an existing topology
- Open the tool and leave New Topology? unchecked.
- Set Input Topology to the existing topology.
- Click Run.
