Colouring

The Colouring tool allows you to colour the surface using various methods.

Colouring options

In the Colouring tool on the Home page, select the desired colouring method and configure as explained below.

Monochrome

Monochrome colouring applies a single colour uniformly to the surface.

• To change the uniform colour, click on the colour swatch below the Monochrome radio button to show the colour picker.

  

  • Adjust the colour as desired using the hue slider or saturation–lightness picker.

    Alternatively, you can specify a colour by hexadecimal (hex), RGB (red–green–blue), or HSL (hue–saturation–lightness) code using the field at the bottom. Click the spinner arrows to the right of the field to cycle through the colour code methods.

• Select Highlight fringes to make any fringes visible. Click on the corresponding colour swatch to change fringe highlight colours, as above.

Elevation

The Elevation colouring option colours each part of the surface by elevation according to a configurable colour map.

See Configuring colour maps on this page for details on configuring the elevation colour map.

Slope angle

The Slope colouring option colours the surface by slope angle according to a configurable colour map.

See Configuring colour maps on this page for details on configuring the slope colour map.

Time since capture

The Time since capture colouring option colours the surface by the ages of the contributing surfaces relative to the currently selected date. Click Colour map... to configure the colour scheme. This is particularly useful for quickly identifying the parts of the surface that have not been updated recently and may require resurveying.

See Configuring colour maps on this page for details on configuring the colour map.

Elevation change

The Elevation change colouring option colours the surface by the change in elevation over a given time period or the deviation from a design surface, according to a configurable colour map. This colouring option is useful to quickly visualise which parts of an operation have been subject to the most activity.

• Select the Date Range tab and configure the Start time and End time fields to define the period of time over which to calculate the elevation change.
• Select the Design tab, then select the design surface from which to calculate the deviation in elevation.
• Click Colour map... to configure the surface colour scheme. See Configuring colour maps on this page for details on configuring the elevation change colour map.

Contours

Select the Contours checkbox to apply contour lines to the surface. Enter the required elevation intervals.

Imagery

The Imagery colouring option overlays the coloured model with aerial or satellite images, according to the provider selected in Imagery Settings, as follows:

• Bing Maps: GeoSpatial Manager retrieves images that match the coordinates of the view and overlays them on the surface.

• Mapbox: GeoSpatial Manager displays all images for the view that were captured earlier than the selected date and time, up to a maximum of 15.

• ArcGIS: GeoSpatial Manager displays all imagery at once. Imagery in ArcGIS exists as one file without time stamping.

  See Surface Imagery for more detail.

Configuring colour maps

To configure the colour map for colouring methods that use one, follow these steps.

1. Click the Colour map... button under the colouring option.

   

   The Customise Colour Map panel appears.

   

2. Choose a colour map to start with. You can either customise the colour map as it is currently defined, or load a preset or saved colour map, which you can then further customise.

   • To load a preset colour map, click From Preset and then select a preset colour map from the list.

     

   • To load a previously saved colour map, click From Library and then select a saved colour map from the list.

3. Configure the colour map as follows.

   Solid / Smooth	Select from the following colour map interval types: Solid: Use discrete intervals, each coloured with a solid colour. Smooth: Use continuous intervals, interpolating the colours between each defined interval.
   Select unit	From the Unit drop-down, select the unit for the colour map. This unit will be displayed on the legend in the view. Tip:  Select the unit before setting the interval boundaries, as changing the unit will convert the values from the current unit to the new unit.
   Interval picker	Configure the colour map intervals using the interval picker. The range of values for intervals should be appropriate to the type of data to be coloured and the expected data value range. The Elevation colour map tool displays the minimum and maximum elevations of the surface (see Min and Max in the image below). To define an interval boundary value, click in its numeric field and enter the boundary value. Interval boundaries must maintain ascending order from left to right. If you change the value of a boundary to be less than its left neighbour, or greater than its right neighbour, the boundaries will automatically be reordered. To define the colour for an interval (solid colouring) or at an interval boundary (smooth colouring), click on the colour swatch to show the colour picker and choose a colour. To insert a new interval boundary, click the button between two existing intervals. To remove an interval boundary, click its button. The Lower and Upper colours define how to colour data below and above the lower and upper interval boundary values, respectively. The Unknown colour will be used to colour any data with an unknown value.
   Preview	This displays a preview of what the resulting legend will look like.

4. Optionally save the current settings.

   • If the current colour map was loaded from a colour map saved to the library, click Save to overwrite the saved colour map.

   • To save the colour map to the library under a new name, click Save As and then enter a new name for the colour map.

5. Click OK or Apply.
