RockWorks | Utilities | Linears | Lineation Map
This program is used to create a map of lineations from line endpoint data. You can adjust the lines style and thickness, and impose a filter based on lineation length.

Step-by-Step Summary
Menu Options
- Input Columns: The prompts along the left side of the window tell RockWorks which columns in the input datasheet contain what data.
Click on an existing name to select a different name from the drop-down list.
- X1, Y1: Select the names of the columns in the data sheet that contain the X and Y coordinates for the beginning points of the lineations.
These can be Eastings in meters or feet, decimal longitudes, etc. See Defining your Datasheet Coordinates for more information.
- X2, Y2: Select the columns that contain the X,Y coordinates for the endpoints of the lines.
- Line Colors & Styles: Use these settings to define how the lines will be plotted.
- Uniform: Select this option to plot all lines using the same line style and color.
- Line Style: Click on the sample to select the fixed style and color.
- Defined by Column: Choose this option if you have line styles listed in the datasheet.
- Column: Click on the column name displayed to the right to choose the name of the column where the lines are listed.
- Azimuth Filter: Expand this heading to activate one or two filters based on bearing.
- Azimuth Filter #1: If you wish to omit lineations from the map based on their bearing, insert a check in this box. Expand this item to establish the bearing filter range for the lineations to be included in the map.
! The program will assume this is bi-directional.
- Tip: Use the Linears | Lineation Properties tool to compute and record the bearing of each lineation in the datasheet.
- Minimum, Maximum: Click on these prompts to type in the minimum and maximum bearing to be included in the map.
- Azimuth Filter #2: If you wish to invoke a second filter, insert a check here and follow the instructions for the Filter #1, above, for lineations to be included in the map.
- Length Filter: To exclude lineations from the map based on their computed length, insert a check in this check-box. Expand this item to establish the filter range.
- Tip: Use the Linears | Lineation Properties tool to compute and record the length of each lineation in the datasheet.
- Minimum Length Filter: Insert a check here to activate a filter that will omit lines shorter than the length you specify. Expand this heading to enter the minimum length, in your map units.
- Maximum Length Filter: Insert a check to activate a filter that will omit lines longer than the length you specify. Expand this heading to enter the maximum length, in your map units.
Step-by-Step Summary
- Access the RockWorks Utilities program tab.
- Create a new datasheet and enter/import your line endpoint data (X1Y1X2Y2) into the datasheet.
Or, open one of the sample files and replace that data with your own. (In the Samples folder, an example file = "\RockWorks17 Data\ Samples\Lineation_Map_01.rwDat".)
- Select the Utilities | Linears | Lineation Map menu option.
- Enter the requested menu items, described above.
- When all of the settings are established to your satisfaction, click the Process button at the bottom of the window.
The program will create a map with the lineations represented with lines, plotted from the lineation beginning to ending points. The completed map will be displayed in a RockPlot2D tab in the Options window.
- You can adjust any of the settings in the Options window (diagram settings, etc.) and then click the Process button again to regenerate the map.
! Each time you click the Process button, the existing display will be replaced.
- View / save / manipulate / export / print the map in the RockPlot2D window.
