RockWorks | Utilities | Maps | Polyline Maps | Multiple (Simple)
Use this program to read a listing of separate polyline files, each containing XY point coordinates, and display the polylines in a 2D map using a uniform line style and color. The map is displayed in RockPlot2D, where you can append it to other maps, etc.

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. See a sample data layout below.
- File Name: Column that contains the names of the external .rwDat files containing the polyline vertices.
Tip: use the File | Import | Create File List program to quickly create a list of specified file names.
- Line Type & Color: Click to the right to select the line style, thickness, and color for all of the polylines.
- Border: Check this to include a border around the polyline map which shows the coordinate range of the axes. Expand this heading to establish the border options.
Step-by-Step Summary
- Access the RockWorks Utilities program tab.
- Create a new datasheet and enter or import your X and Y coordinates into the datasheet.
Or, open one of the sample files and replace that data with your own. (In this example, the sample file = "RockWorks17 Data\ Samples\Polylines_Simple_01.rwDat".)
You can use the Columns | Column Properties menu option to establish the file-name column (such as "Polyline XYZ File" shown here) as containing linked data, specifically another .rwDat file. Doing so allows you to double-click in one of the cells to display the contents of the linked file.
Each of the .RwDat files listed here needs to list the X and Y coordinates for the vertices of a single polyline:
Longitude and latitude coordinates must be in decimal format. If you're using another coordinate system, be sure you've specified the Units and the Projection Settings as appropriate.
- Select the Map | Polyline Maps | Multiple Polylines (Simple) menu option.
- Enter the menu settings as described above.
- Click the Process button to continue.
The program will construct line segments between the coordinate pairs in each listing, in the line color, style, and thickness you specified. 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 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.
