Displaying Drillholes

Viewing drillhole data in the scene is an important part of refining drillhole data and building a geological model. Therefore, Leapfrog Geo has a number of different tools for displaying drillhole data that can help in making drillhole data processing and modelling decisions. This topic describes those display options and is divided into:

Display drillhole data in the scene by dragging the Drillholes object into the scene. You can also drag individual tables into the scene.

Once drillhole data is visible in the scene, click on a drillhole to view the data being displayed. You can also display the data associated with each interval by clicking on the Show text button () in the shape list. Here, data display is enabled for two interval tables:

The Show trace lines button () in the shape list displays all trace lines, even if there is no data defined for some intervals. The Filter trace lines option in the shape properties panel displays only trace lines for drillholes selected by a query filter. See Query Filters for more information.

Displaying Drillholes as Lines or Cylinders

You can display drillholes as lines or points. You can also display the data associated with each segment. Here, the drillholes are displayed as flat lines:

The width of the lines is set in the shape properties panel.

When the Make lines solid button () is enabled, the drillhole data is displayed as cylinders and the property that can be controlled is the Line radius:

Hiding Lithologies

When lithology tables are displayed, you can hide some of the lithologies to help make better sense of the information in the scene. Click the Edit Colours button to open the lithology legend, then use the Show/Hide buttons () to determine what segments are displayed:

To select multiple lithologies, use the Shift or Ctrl keys while clicking. You can then change the visibility of all selected lithologies by clicking one of the visibility () buttons.

Hiding lithologies in this way only changes how the data is displayed in the scene. Another way of limiting the data displayed is to use a query filter (see Query Filters), which can later be used in selecting a subset of data for further processing.

Displaying a Legend

To display a legend in the scene, click the Show legend button () for the table:

The legend in the scene will be updated to reflect lithologies that are hidden in the scene when you click Edit Colours and hide some lithologies.

Changing Colourmaps

To change the colours used to display lithologies, click on the Edit Colours button in the shape list. In the window that appears, click on the colour chip for each lithology and change it as described in Display Colours.

To set multiple lithologies to a single colour, use the Shift or Ctrl keys to select the colour chips you wish to change, then click on one of the colour chips. The colour changes you make will be made to all selected lithologies.

You can also import a colourmap, which is described in Colourmap Import.

Viewing Multiple Interval Tables

When viewing multiple interval tables, use the line and point size controls and the transparency settings to see all the data at once. For example, here, the geology table has been made transparent to show the contaminant intervals inside:

Selecting from Multiple Columns

When an interval table has more than one column of data, select the column to view from the view list:

Some columns are editable, in which case you can click on the Edit button () to start editing the table:

Displaying Interval Data in the Scene

Drillholes can be displayed with the data associated with each segment. For example, in the scene below, contaminant values are displayed along the drillhole:

To view data in this way, select the table in the shape list, then click on the Format Text button. In the Text Format window, click Insert Column to choose from the columns available:

You can display multiple columns and add text:

Click OK to update the formatting in the scene. You can conceal the formatting in the scene by clicking on the Show text button () in the shape list:

Clear text formatting by clicking on the Format Text button, then on Clear.
