Mapping

Mapping data is:

• The cutting edge elevation recorded as the machine works. This is called Latest Pass mapping; OR
• The cutting edge elevation recorded for a particular location, only if the measured elevation is less than the previously recorded elevation. This is called Minimum Elevation mapping.

You can also optionally:

• Display the cut/fill differences between the recorded map data and the guidance surface.

• Display an initial map generated from the cut/fill differences between a pre-mapped surface, called a ground surface, and the guidance surface.

  For example, if the ground surface is based on a survey of the original site, then the initial map could enable you to move dirt around the site more efficiently.

  NOTE – The ability to select a ground surface is a licensed feature. Contact your dealer for more information

Using mapping

The following systems support mapping:

• Systems with GS5x0 sensors on the front linkage
Caterpillar Cat Grade Control E and F Series Excavators
Caterpillar Build 07 Series Excavators

Mapping is available when you have an office or in-field design loaded.

The shortcut key

When you are in the work screen, you can use one of the following shortcut keys to turn the display of cut/fill mapping data on and off:

• If Latest Pass mapping is selected, is displayed.
• If Minimum Elevation mapping is selected, is displayed.

You can also touch and hold the shortcut key to open the Cut/Fill Mapping screen.

Mapping rules

Mapping data is collected when the following conditions are met:

• Autos is in the engaged (green) state, OR

• The bucket is within 1 m (39 ½ inches) above design or any distance below design, AND

  For systems with a non-rotating bucket, the bucket is moving towards the cab and is positioned for cutting.

  For systems with a rotating bucket:

  • The bucket is moving towards the cab and is rotated ± 90° from 0°.
  • The bucket is moving away from the cab and is rotated ± 90° from 180°.

Start mapping with an empty map

To start mapping with an empty map:

1. From the Work Settings menu open the Cut/Fill Mapping screen, or touch and hold or in the shortcut bar.
2. Optionally, toggle Display Mapping Data on or off.
3. Optionally, select a Mapping Mode of Latest Pass or Minimum Elevation.
4. If available, from the Ground Surface drop down, select None.
5. Tap Apply.

Start mapping with a pre-mapped surface

To start mapping with a pre-mapped surface:

1. Transfer a ground surface .ttm file onto the machine. Either sync with Connected Community or import the ground surface file from a USB flash drive.

   NOTE – If a Connected Community sync adds a new ground surface .ttm file to the current project, then a notification is displayed.

   NOTE – To import a ground surface .ttm file from a USB flash drive, the ground surface file must be in the ProjectLibrary \ Projects \ [project name] \ OfficeData folder on your USB flash drive.

2. From the Work Settings menu open the Cut/Fill Mapping screen, or touch and hold or in the shortcut bar.
3. Optionally, toggle Display Mapping Data on or off.
4. From the Ground Surface drop down, select the ground surface file to load.
5. Optionally, select a Mapping Mode.

6. Tap Apply. If Display Mapping Data is on, a cut/fill map is generated showing the difference between:

   • The guidance surface of the currently loaded design; and
   • The ground surface

As you work, the pre-mapped ground surface elevations are overwritten by the measured elevations.

If you select a different design within the same project, the cut/fill map regenerates using the new design.

Downloading ground surface data from an online source

If your technician has enabled access, you can request the system to download the latest ground surface data in a .ttm file from an online source. This includes data from other machines on the site.

This option downloads data once when requested.

1. On the Cut/Fill Mapping screen, set the Ground Surface field to WorksOS download.
2. Tap Apply.

Downloading information for a large area can take a while.

Deleting map data

To delete any existing mapping data stored on the machine:

1. From the Work Settings menu open the Cut/Fill Mapping screen, or touch and hold or in the shortcut bar.
2. Tap Reset Map.

If a pre-mapped surface was initially loaded and Display Mapping Data is on, then the cut/fill map of the differences between the design surface and the pre-mapped surface is reset to its original state.

Inspecting a map

To view details of the mapping data on a plan view, touch-and-hold on an onscreen location where mapping data is recorded. Select Inspect Map from the context menu.

The work screen

Work screen items that affect the recording and display of mapping information are described in the following sections.

The guidance bar

The target icons relevant to Mapping are shown below:

Use the offset icons in the following ways:

• Tap to cycle through the configured offset memories.
• Touch and hold to access the respective offset configuration screens.

The guidance view

The guidance view displays the machine relative to the surface being worked. You can set up to three different views to display mapping data at once:

• Cross-section
• Profile
• Plan

Mapping data is displayed in the following way:

Color	Meaning
Shades of red	The shaded area is above the working surface elevation (cut).
Shades of green	The shaded area is within on-grade tolerance of the working surface elevation (on-grade).
Shades of blue	The shaded area is below the working surface elevation (fill).
Gray	Cut/fill values are being calculated and loaded.

System Settings

The System Settings icon is in the lower left-hand side of the work screen:

Use System Settings to access and configure various functions, including (but not limited to):

• Grade Tolerance
• File Transfer

The shortcut bar

The shortcut bar enables you to easily perform frequently repeated tasks. The shortcut icons for mapping are:

• (Latest Pass), or;
• (Minimum Elevation)

To display or hide mapping data, tap the mapping icon in the shortcut bar.

To open the Cut/Fill Mapping settings screen, touch and hold the mapping icon.

Work Settings menu

The Work Settings icon is in the lower right-hand side of the work screen:

Use the Work Settings menu to access and configure those settings that change according to the requirements of each individual task, including (but not limited to):

• Cut/Fill Mapping
• Elevation Offset

For more information

See these guides in the overflow menu:

• Transferring Files
• Using Elevation Offsets
