Lineation Data

Example 1 - Lineation Endpoints

Lineation endpoint data can be entered into the RockWorks datasheet for the purposes of computing lineation azimuth/midpoint/lengths and lineation densities & intersections, and for creating rose diagrams, lineation maps, and arrow maps. These tools are in the Linears menu.

Example

Column Summary

• ID: Optional. Lists the sample number or name for each lineation.
• X1 Y1: Required. List the X,Y coordinate for the beginning of each line.
  These may represent a local coordinate system, or a global coordinate system such as UTM or longitude/latitude. See Defining your Datasheet Coordinates and Units for information.
• X2 Y2: Required. List the X,Y coordinate for the end of each line.
• Line Style and Color (optional): Lists the style and color for each lineation, used for lineation maps and arrow maps, though not required (a fixed style can be selected).

Example 2 - Lineation Bearings

Lineation bearing data can be entered into the RockWorks datasheet for the purposes of creating rose diagrams in the Linears menu.

Example

Column Summary

• ID: Optional. Lists the sample number or name for each measurement.
• Bearing: Required. Lists the 0 - 360 degree azimuth bearing of the line, in decimal degrees. OR lists the bearing in quadrant notation. When noting bearing in quadrant notation, you can use either upper- or lower-case characters, and the notations can be without spaces (as shown above) or with single spaces between direction and measurements.
