Indent Keyword Scheme

Indent keyword schemes link words and numbers in an table with indent line styles and line properties for a lithology log. The indent line styles can show transgressive or regressive sequences, can represent how eroded various layers are compared to other layers (for example, shale is more highly eroded compared to the surrounding sandstones), or can use a wavy line to represent undulations or cross bedding on layers.

Important: the indent keyword scheme item names must match the keyword in the table column for the scheme item properties to be shown on the log. Keywords are case-sensitive.

Creating an Indent Keyword Scheme

To create an indent keyword scheme based on existing data in the project:

Click the Home | Display | Scheme Editor command.
In the Scheme Editor, click the button to open the New Scheme dialog.
In the New Scheme dialog, select Base Scheme on Column Data, which allows you to determine the source column of data on which to base the scheme.
Click the box next to Table Name and select the table that contains the scheme information from the list.
Click the box next to Column Name and select the column that contains the scheme information from the list.
Type a Scheme Name.
Select Indent Keyword as the Scheme Type.
The Interval Count is automatically set to the number of unique items in the Column Name.
Click OK to close the New Scheme dialog.
In the Scheme Editor, click on the next to Indent Keyword.
Click on the desired scheme name.
Click on the next to the scheme name in the Indent Keyword list.
Select each scheme item and edit the properties on the right side of the dialog.
Click OK to exit the Scheme Editor and save the properties of the new scheme.

Editing an Indent Keyword Scheme

To edit an indent keyword scheme:

Click the Home | Display | Scheme Editor command.
In the Scheme Editor, click on the next to Indent Keyword.
Click on the desired scheme name.
To change the scheme name, on the right side of the dialog, type a new name next to Name and press ENTER on the keyboard. The scheme name is updated.
To change a scheme item name,
1. Open the scheme by clicking the next to the scheme name.
2. Click a scheme item name.
3. On the right side of the dialog, click the next to Indent Keyword Properties, if necessary.
4. Type a new name next to Keyword and press ENTER on the keyboard. The scheme item name is updated.
To change scheme item properties,
1. Open the scheme by clicking the next to the scheme name.
2. Click a scheme item name.
3. On the right side of the dialog, edit the shape of the lithology indent line or the line properties.
Click OK to exit the Scheme Editor and save the properties of the scheme.

Important: the keyword scheme item names or numbers must match the keyword in the table column for the scheme item properties to be shown on the log. Keywords are case-sensitive.

Data Requirements

Indent keyword schemes require a column of text or numbers. Note that keywords are case-sensitive.

Using Indent Keyword Schemes

Once a indent keyword scheme is defined you can use it with multiple data tables in multiple projects. Click on the lithology log to select it. In the Property Manager, check the box next to the Use Indent Keyword Scheme option and set the Indent Keyword Scheme to the desired scheme.

Lithology Indent Lines

The lithology indent lines form the shape of one side of the lithology layer in the lithology log.

This lithology log displays various

indent line styles on the right side.

Choose an indent line style for each scheme item by clicking on the scheme item and then selecting the Lithology Indent Lines type for that scheme item. To see available types, click on the line to the right of Lithology Indent Lines and select the desired style from the list.

Select from a list of predefined indent lines.

Customizing Line Styles

If you wish to import a new line, click on the line style next to the Lithology Indent Lines option. In the list that appears, click the Modify button.

Click Modify in the list to

add new line styles.

The Lithology Indent Lines dialog opens:

The Lithology Indent Lines dialog allows you to manage,

save, and import lines used in Indent Keyword schemes.

Importing Lines

Line indent styles are simple vector line files. There are line styles available in Strater, or you can create your own in another program or in a text editor. Strater imports Atlas Boundary (*.BNA), Golden Software Blanking (*.BLN), and Strater Lithologic Lines (*.LLF) files for lithology indent lines.

The following are requirements for imported indent line files.

The limits of the file must be from 0 to 1000, otherwise the line cannot be imported.
The X and Y coordinate range must be zero to 1000. Values cannot be negative.
The first Y value must be zero.
The last Y value must be 1000.
The coordinate (0,0) is in the upper left corner and (1000,1000) is in the lower right corner.

(0,0) is the upper left corner.

(1000,1000) is the lower left corner.

To import a file to be used as an indent line:

Click the button in the Lithology Indent Lines dialog.
In the Open Lithology Indent Lines dialog, browse to the folder containing the file to import.
Select the file and click Open.
If an error message occurs saying Unable to import all lithology indent curves, the file probably does not meet the coordinate requirements. Edit the original file to meet the requirements above and try to import again.
If the file imports, all new lines are displayed at the bottom of the list.
Select the desired indent line and click OK to return to the Scheme Editor.
Click OK or Apply to make the change on the view window.

Exporting Indent Line Styles

All of the lines in the Lithology Indent Lines dialog can be saved for use on other computers.

In the Lithology Indent Lines dialog, click the button. The Save Strater Lithology Indent Lines dialog opens.
Use the Save In field to select the location where you want the line file saved.
Enter the name of the line in the File Name field. All indent lines are saved in file format .LLF.
Click Save to save the line.

Deleting Indent Line Styles

Select any line in the Lithology Indent Lines dialog and click the button to delete the selected line. Note: The first three indent line styles (Straight, Slope Down, and Slope Up) cannot be deleted.

Renaming Indent Line Styles

To rename any line, click on the line in the Lithology Indent Lines dialog. Type a new name in the box on the upper right side. The name is saved when the OK button is clicked. Note: The first three indent line styles (Straight, Slope Down, and Slope Up) cannot be renamed.
