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:
ModeRequired in practice
New topologyInput Point Feature, Input Boundary Feature
Existing topologyInput 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.

Parameters for Point On Boundary
ឈ្មោះប្រភេទទិន្នន័យការពិពណ៌នា
New Topology?ជម្រើសBoolean

Selects the mode.

  • Checked — A new topology is created from Input Point Feature and Input Boundary Feature.
  • Unchecked — The existing topology named in Input Topology is used.
Input Topologyជម្រើសTopology

The existing geodatabase topology to validate. Used when New Topology? is unchecked.

Input Point Featureជម្រើសFeature Layer

The boundary point layer to test. Point geometry only. Used when New Topology? is checked.

Input Boundary Featureជម្រើសFeature 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

  1. Confirm the point and polygon layers are in the same feature dataset.
  2. On the KGA Toolbox tab, in the Geoprocessing group, open the Topology gallery and click Point On Boundary.
  3. Check New Topology?.
  4. Set Input Point Feature to the boundary point layer.
  5. Set Input Boundary Feature to the parcel polygon layer.
  6. Click Run, then review the reported errors in the error inspector.

Reuse an existing topology

  1. Open the tool and leave New Topology? unchecked.
  2. Set Input Topology to the existing topology.
  3. Click Run.
