High Point — How To Read
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.
High Spots
A high spot is meaningful only relative to the intended surface. It may obstruct runoff, limit cultivation depth or sit above a construction formation. Cutting it without knowing the target can remove useful soil unnecessarily.
Before moving material
Measure the feature against surrounding levels and the agreed datum.
Receiving operation and checks
Recheck the corrected level and restore the appropriate surface layer. Check whether the high spot was a local deposit or part of the intended contour.
A visible mound is not automatically a defect.

Surveying for grading establishes the relationship between the site and the intended surface. Machine guidance can assist work, but the survey determines the reference against which results are checked.
Before moving material
Define the survey area, control and required deliverables.
Receiving operation and checks
Use the survey to prepare the design and later acceptance checks. Retain the datum, units and control-point descriptions.
A topographic survey and a legal boundary survey serve different purposes.

An existing-surface survey records what is present before soil moves. Omitting a drain edge, bank or abrupt grade change can distort the volume model even when point readings are correct.
Before moving material
Identify the work extent and important surface features.
Receiving operation and checks
Compare the surveyed surface with the proposed design. Inspect coverage and gaps rather than relying only on a coloured map.
Survey spacing must reflect terrain and required precision, not a universal grid size.
