ទិដ្ឋភាពទូទៅ
Where Parcel Split Tool applies a division rule you specify, this tool solves the layout: give it the constraints and it finds a lot arrangement that satisfies them.
ការប្រើប្រាស់
- Subdivision Method selects the layout algorithm, and the choice matters more than any other single setting:
| Method | Behaviour |
|---|---|
Legacy_Frontage (default) | Lays lots out along road frontage. The most realistic for typical street-fronting subdivisions. |
Grid | A regular grid of lots. Efficient on rectangular parcels, poor on irregular ones. |
Voronoi | Lots grown from seed points. Handles irregular parcels but produces non-rectangular lots. |
Genetic | A search-based optimiser. Can find better layouts on awkward parcels, at the cost of a considerably longer run time. |
- Input Road Access is optional but effectively required for
Legacy_Frontage, which needs road geometry to lay lots against. Without it, the method has no frontage to work from. - Parameters are grouped into categories on the dialog:
| Category | Controls |
|---|---|
| Subdivision Setting | Minimum and maximum lot size, zoning type |
| Setback Setting | Road, side, and rear setbacks |
| Lot Rule | Minimum frontage, minimum and maximum depth |
| Frontage Analysis | Road search distance, frontage buffer |
- Maximum Depth defaults to
0, which means unlimited. Set an actual value to prevent unusably deep lots on a large parcel. - Road Search Distance defaults to
150— how far the tool looks for a road to front lots against. Increase it if the parcel sits back from the road; the default may find no frontage at all for a deep rural parcel. - Frontage Buffer defaults to
5and sets the tolerance used when deciding what counts as road frontage. - Constraints can conflict. A minimum lot size, minimum frontage, minimum depth, and generous setbacks may together be unsatisfiable inside the parent parcel — relax one of them if the result contains few or no lots.
- Output Subdivision Lines is optional and writes the lot boundary lines as a separate layer, for symbolising the layout.

របៀបប្រើ
- Add the parent parcel and the road layer to the map.
- On the KGA Toolbox tab, in the Geoprocessing group, open the Cadastral Tools gallery and click Parcel Split Optimizer.
- Set Input Parent Parcel, and set Input Road Access to the road geometry.
- Leave Subdivision Method as
Legacy_Frontagefor a street-fronting layout. - Under Subdivision Setting, set Minimum Lot Size, optionally Maximum Lot Size, and the Zoning Type.
- Under Setback Setting, enter the road, side, and rear setbacks required by the local rules.
- Under Lot Rule, set Minimum Frontage and Minimum Depth. Set Maximum Depth if deep lots must be prevented.
- Under Frontage Analysis, increase Road Search Distance if the parcel sits well back from the road.
- Set Output Subdivision Lots, and Output Subdivision Lines if you want the boundary lines separately.
- Click Run. If few or no lots are produced, relax one of the constraints — most often the minimum lot size or the setbacks — and run again.
