Gnss Grading — Faq Visual for Irrigation

Irrigation Landforming

Irrigation landforming connects the field surface to the method of applying water. The appropriate design depends on the supply, soil and planned operating sequence.

Before moving material

Survey field levels together with water-supply and drainage structures.

Receiving operation and checks

Check the formed field before the next cultivation or irrigation operation. Observe advance and recession of water where practical rather than relying only on a dry appearance.

Landforming is one part of irrigation performance, not a guaranteed efficiency percentage.

Irrigation Bay Levelling

An irrigation bay needs a planned relationship between inlet, surface, banks and outlet. Local low areas can retain water while high areas delay its movement.

Before moving material

Record bay dimensions, boundary levels and existing supply/outlet details.

Receiving operation and checks

Recheck levels and observe an irrigation event before declaring the bay complete. Inspect the far end and corners for residual depressions.

No single bay slope or inlet setting suits every soil and water supply.

Dugong + GPS/GNSS Grading

Using Dugong with GPS/GNSS grading requires a complete positioning and implement-reference workflow. Antenna position must be related to the working edge and the issued surface design.

Before moving material

Confirm corrections, datum and the intended control installation.

Receiving operation and checks

Survey or otherwise independently check the resulting grade. Record interruptions and the design revision used.

A tractor's navigation system alone does not establish scraper grade-control capability.

Record the job inputs

Use this checklist to turn the scenario into a specific brief. Retain the design revision and agree who accepts each completed layer.

• Existing condition, extent and the reason for intervention
• Required finished purpose, receiving operation and acceptance criteria
• Material type, layer role, source, receiving area and volume state
• Reference levels, datum, survey method and issued design revision
• Available tractor, implement configuration, travel route and turning space
• Checks before work, stopping points and evidence retained at handover

Checklist ticks apply only while this page is open. Include the completed brief in your project records.
