ទិដ្ឋភាពទូទៅ

An adjacency table is the foundation for neighbour notification lists, boundary dispute analysis, and any question of the form "which parcels border this one".

ការប្រើប្រាស់

  • Adjacency Type decides what counts as adjacent: For neighbour notification, Shared Edge is usually correct; a diagonal corner touch is not a shared boundary in practice.
    • Shared Edge (default) — Parcels are neighbours only if they share a boundary segment. Two parcels meeting at a single corner point are not neighbours.
    • Shared Edge or Corner — Corner-only contact also counts.
  • Write Both Directions controls table symmetry: Check it when the table will be joined or queried by parcel; leave it unchecked for a compact pair list.
    • Unchecked (default) — Each pair is written once. Parcel A → B appears, but not B → A. Compact, but a lookup on a given parcel must search both columns.
    • Checked — Each pair is written twice, once in each direction. The table is twice the size, but a query on one parcel column returns all its neighbours.
  • Include Shared Boundary Length is on by default and records the length of each shared boundary in the layer's coordinate system units. This is what distinguishes a substantial common boundary from a few centimetres of incidental contact.
  • Run Parcel Overlap Check first. Overlapping parcels produce misleading adjacency results, because an overlap is reported as shared boundary.

Parameters for Parcel Adjacency
ឈ្មោះប្រភេទទិន្នន័យការពិពណ៌នា
Input Parcel LayerFeature Layer

The parcel layer to analyse.

Parcel ID FieldField

The field identifying each parcel. Its values populate both parcel columns of the output table.

Output Neighbor TableTable

The table recording the adjacency pairs.

Adjacency TypeString

What counts as adjacency. Default is Shared Edge.

  • Shared Edge — a shared boundary segment is required
  • Shared Edge or Corner — corner-only contact also counts
Write Both Directionsជម្រើសBoolean

Controls whether each pair is written once or twice.

  • Checked — Both A→B and B→A rows are written.
  • Unchecked (default) — Each pair appears once.
Include Shared Boundary Lengthជម្រើសBoolean

Records the length of each shared boundary, in the layer's coordinate system units.

  • Checked (default) — Shared length is included.
  • Unchecked — Only the pair is recorded.

របៀបប្រើ

  1. Run Parcel Overlap Check and resolve any overlaps.
  2. On the KGA Toolbox tab, in the Geoprocessing group, open the Cadastral Tools gallery and click Parcel Adjacency.
  3. Set Input Parcel Layer and Parcel ID Field.
  4. Set Output Neighbor Table.
  5. Set Adjacency Type — leave it at Shared Edge unless corner contact must count.
  6. Check Write Both Directions if the table will be queried by parcel.
  7. Leave Include Shared Boundary Length checked so short incidental contacts can be filtered out later.
  8. Click Run.
