5.7 | Markers & Benchmarks

Tap

Level COMMAND allows important locations within a project to be recorded using Markers and Benchmarks. Although both are created using the 'same tool, they serve different purposes during surveying, grading and future site visits.

Markers provide useful reference points for operators and designers, while Benchmarks provide permanent reference locations used for project alignment and zeroing.

Marker Types

Two marker types are available:

DropGeneral POIMarkers'

button

General onMarkers record locations or features of interest within a project. They are commonly used to identify:

Trees or obstacles Fence lines and gateways Irrigation equipment Utility crossings Rocks or hazards Other significant site features

General Markers provide useful visual reference points but cannot be used when performing a benchmark zero.

Benchmark Markers

Benchmark Markers are permanent reference locations used for project alignment and zeroing.

Unlike General Markers, Benchmark Markers can be selected from the rightZero sideto Benchmark tool and allow a project to be accurately re-aligned during future grading operations.

Creating a Marker

To create a General Marker or Benchmark Marker:

Press Marker from the Apply View. Enter a descriptive marker name. Enable Create Benchmark if the marker will be used for zeroing. Press Create.

The current latitude, longitude and elevation are recorded as part of the mainmarker.

Markers During Surveying

Markers can be created at any time, but they are particularly useful while surveying.

Recording important locations before exporting survey data allows those features to become part of the exported project, providing valuable reference information for designers, contractors and yourfuture currentmachine latitude,operators.

longitude,

Common markers recorded during a survey include:

Benchmark locations Gateways and elevation.
access points Fence corners Irrigation infrastructure Power poles and utility crossings Trees or significant obstacles Drain inlets, outlets and other important field features

Including these reference points within the survey often reduces the need for additional site visits and improves communication between the operator and designer.

If an imported project already contains surveyed Benchmarks, these should normally be used instead of creating new ones.

Important Considerations

Creating a Benchmark does not improve yourGNSS accuracy.

Instead, Benchmarks improve repeatability by allowing the machine to GPSreturn drift,to itthe same physical reference point whenever the project is revisited.

When collecting a benchmark, it is very important that you do so on a flat area without wheel ruts that won't get cut or filled, with the blade on the ground, and that the spot is identifiable in some way.
