Digital Terrain Model — Turf Use
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
Digital Terrain Models
A digital terrain model represents a surface from measured or designed data. It can guide cut-and-fill calculations, but poor boundaries and missing breaklines can create a misleading model.
Before moving material
Confirm data source, coordinate system and model extent.
Receiving operation and checks
Issue a controlled design model for the intended workflow. Compare selected model elevations with known field observations.
A model image is not proof of survey accuracy or a certified design.

Uneven turf formation may arise beneath the growing layer or within it. Repeatedly topdressing the visible depression may leave the formation issue unresolved.
Before moving material
Locate the uneven area and identify the turf system's layer arrangement.
Receiving operation and checks
Restore the specified growing surface and turf. Check local levels, layer depth and drainage after the repair.
The correct treatment depends on the turf system and cannot be inferred from a photograph.

Turf underlay needs a consistent growing layer over a correctly formed base. A smooth top surface can conceal an uneven distribution of suitable soil.
Before moving material
Check the formation and the growing-medium requirements.
Receiving operation and checks
Complete the venue's final soil preparation and turf installation. Check local low areas and underlay thickness.
Do not infer a turf rootzone specification from the word underlay.
