Structural Data

In Leapfrog Geo, you can create and edit structural data tables directly or from other objects in the project. Structural data can also be used to create and edit many surfaces. Downhole structural data can also be imported, although structural data tables imported in this way cannot be edited.

This topic describes how to work with structural data in Leapfrog Geo. It covers:

New Structural Data Tables

There are two ways to create a new structural data table in Leapfrog Geo:

  • Create a new table as part of creating or editing another object. See Extent from Structural Data and Editing Surfaces with Structural Data.
  • Create a new table using the Structural Data folder. Use this technique when, for example, you are creating structural data points from a map or image. Right-click on the Structural Data folder and select New Structural Data. In the window that appears, enter a name for the new table and click OK.

Before creating the new data table, add the map, image or data object you wish to work from to the scene and orient the scene for drawing the new data points.

When a new structural data table is created, it will be added to the scene. The Structural Data window will open, together with a set of tools for adding structural data points:

Click on the New Structural Data Point button () and click and drag along the strike line in the scene to add a new data point:

You can adjust the data point using the controls in the Structural Data window:

If you wish to assign points to categories, select New Category from the Base Category dropdown box. In the window that appears, enter a name for the category, then click Create Category:

When adding additional data points, you can then select the new category from the Base Category list.

When you have finished adding data points, click the Save button ().

If the data contains categories that you wish to use in building models, define query filters for the categories. You will then be able to select the filter when you are creating a surface:

See Query Filters for more information.

Importing Structural Data

Leapfrog Geo supports structural measurements in .csv or text formats. This topic describes importing structural data tables that include location information. Downhole structural data can also be imported, as described in Importing Downhole Structural Data.

Structural data containing location information can be imported from:

  • Files stored on your computer or a network location. Right-click on the Structural Data folder and select Import Structural Data. You will be prompted to select a file.
  • From any database that runs an ODBC interface. Right-click on the Structural Data folder and select Import Structural Data via ODBC. See Selecting the ODBC Data Source below.

For each of these options, once the data source is selected, the process of importing the data is the same. Leapfrog Geo will display the data and you can select which columns to import:

Leapfrog Geo expects East (X), North (Y), Elev (Z), Dip and Dip Azimuth columns. The Base Category and Polarity columns are optional. The Base Category column can be used for filtering data once it has been imported.

Click Finish to import the data. The structural measurements will appear in the Structural Data folder.

If the data contains categories that you wish to use in building models, define query filters for the categories. You will then be able to select the filter when you are creating a surface:

See Query Filters for more information.

Once the data has been imported, you can reload and append the data in a similar manner to drillhole data. See Appending Drillholes and Reloading Drillhole Data for more information.

Selecting the ODBC Data Source

When importing structural data from an ODBC database, you will need to specify the ODBC data source. Enter the information supplied by your database administrator and click OK.

Once the data source is selected, the importation process is similar to that described above.

Editing Structural Data

Editing structural data tables is similar to editing drillhole data tables. To edit the data in the table directly, double-click on the structural data table in the project tree. See The Table Dialog.

To edit the structural data in the scene, right-click on the table in the project tree and select Edit in Scene. If the table is displayed in the scene, in the shape list, click on the Edit button () in the shape list. The Structural Data window will appear in the scene, together with controls for editing the data points. To edit a data point, click on it. Information about the selected point will be displayed in the Structural Data window, together with controls in the scene you can use to adjust the point:

You can also add new data points in the same manner described in New Structural Data Tables.

Estimating Structural Data

You can generate a set of structural measurements using any points object in the project. To do this, right-click on the points object and select Estimate Structural Data. In the window that appears, enter a name for the structural data table, then click OK. The new structural data table will appear in the project tree and you can view and edit it as described in Displaying Structural Data and Editing Structural Data.
