AI Preferences

When running an AI Assist analysis, you can configure preferences that shape how the AI evaluates and ranks nearby survey marks. This page explains every preference option and how it affects recommendations.

Project type

Tells the AI what kind of work you're doing. The AI uses this to prioritise mark types and characteristics that are most relevant to your project.

Project type	What the AI prioritises
Construction	Marks near the site with high positional accuracy, suitable for setting out
Cadastral survey	Boundary-related marks, permanent survey marks, and marks with strong horizontal accuracy
Engineering survey	Marks with high vertical accuracy for level runs and engineering design
General	Balanced ranking without strong bias toward any mark characteristic

tip

If you're unsure which project type to select, choose General. You can always re-run the analysis with a more specific type if the initial results aren't focused enough.

Priority

Controls the trade-off between proximity and accuracy in the ranking.

• Proximity — Marks closer to your pin are ranked higher, even if their accuracy class is lower.
• Accuracy — Marks with better horizontal and vertical class ratings are ranked higher, even if they're further away.
• Balanced — The AI weighs both proximity and accuracy equally.

Max distance

Sets the maximum search radius from your pin location, in metres. Marks beyond this distance are excluded from the analysis entirely.

• A smaller radius (e.g. 500m) gives you tightly focused results in dense urban areas.
• A larger radius (e.g. 5000m) is useful in rural areas where marks are sparse.

info

If the AI returns fewer results than expected, try increasing the max distance. In remote areas, the nearest marks may be several kilometres from your pin.

Mark status

Filters marks by their current condition. Options typically include:

• Active only — Only marks that are confirmed as existing and usable.
• Include destroyed — Also includes marks that have been reported as destroyed or disturbed. Useful if you need to reference historical mark locations.
• All statuses — No status filtering. Returns marks regardless of condition.

Time window

Restricts results to marks that were last surveyed within a specific time period. This is useful when you need marks with recent observations.

• No restriction — All marks regardless of when they were last surveyed.
• Last 5 years — Only marks with survey observations in the past 5 years.
• Last 10 years — Only marks surveyed in the past 10 years.
• Last 20 years — Only marks surveyed in the past 20 years.

warning

Setting a narrow time window in areas with older survey infrastructure may significantly reduce the number of results. Many marks in regional areas haven't been re-surveyed in decades but are still perfectly usable.

Horizontal class minimum

Sets the minimum acceptable horizontal class for recommended marks. Marks with a horizontal accuracy class below this threshold are excluded.

Horizontal class indicates the positional accuracy of a mark's horizontal coordinates. Lower class numbers indicate higher accuracy.

Vertical class minimum

Sets the minimum acceptable vertical class for recommended marks. Marks with a vertical accuracy class below this threshold are excluded.

Vertical class indicates the accuracy of a mark's height/elevation value. This is particularly important for engineering surveys and level runs.

Additional notes

A free-text field where you can provide extra context to the AI. The AI reads this text and factors it into its analysis.

Example notes:

• "Need marks suitable for a level run along the highway corridor"
• "Prefer marks on public land, avoid marks on private property if possible"
• "Looking for marks with recent GPS observations"

tip

Be specific in your notes. The more context you give the AI, the better it can tailor its recommendations to your actual needs.

Default values

If you don't change any preferences, the AI uses sensible defaults:

Preference	Default
Project type	General
Priority	Balanced
Max distance	Jurisdiction-dependent
Mark status	Active only
Time window	No restriction
Horizontal class minimum	None (all classes)
Vertical class minimum	None (all classes)
Additional notes	Empty

These defaults work well for general exploration. Adjust them when you have specific project requirements.
