Creating Arrow Maps

RockWorks | Utilities | Linears | Arrow-Map

This program is used to read line endpoint coordinates from the datasheet and create a map in which lineations are represented with arrows plotted from the beginning to the ending coordinate pair.

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 arrows will be plotted.
  • Uniform: Select this option to plot all arrows 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.
      
      
• Omit Short Arrows: Insert a check in this check-box to omit arrows less than a specified length. Expand this item to specify the minimum length, in your map units.
• Arrowhead Type: Expand this item to choose either hollow or filled arrowheads.
• Head Size:  Click here to enter a size for the arrowhead, as a percent of map width.  A value of "1.0" will create arrowheads that are approximately 1% of the width of the map.
• Border: Check this to include a border around the arrow map which shows the coordinate range of the axes. Expand this heading to establish the border options.
  
  

Step-by-Step Summary

1. Access the RockWorks Utilities program tab.
2. Create a new datasheet and enter/import your line endpoint (X1Y1X2Y2) data 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\Arrow_Map_01.rwDat".)
3. Select the RockWorks | Utilities | Linears | Arrow Map menu option.
4. Enter the menu settings (above). 
5. 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 arrows, plotted from the lineation beginning to ending points. The lengths shown will represent actual lineation lengths as given by the input X and Y coordinates. The completed map will be displayed in a RockPlot2D tab in the Options window.

6. 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. 
    
7. View / save / manipulate / export / print the map in the RockPlot2D window.
