Converting Quadrant Data to Azimuth Format

RockWorks | Utilities | Coords | Quadrant -> Azimuth

This program is used to translate quadrant-style bearings (i.e. S45E) into decimal-style azimuth bearings (i.e. 135).
Example: S45E = 135.

Note: The geological azimuth format assumes that North is zero and bearings increase clockwise from zero through 360 degrees.

Menu Options

Input Columns:
- Quadrant Column: Click on this item to select the column in the data sheet that contains the quadrant bearings to be translated.
  - Quadrant bearings must listed with the "N" or "S" listed first, either capitals or lower case, plus a degree measurement from north or south heading "E" or "W".
  - You may include spaces between the direction letters and degrees, or not.
  - Please do not spell out the directions, use the "N", "S", "E", or "W" abbreviations. Examples: S45E N27.3E S69W
Output Columns:
- Azimuth Column: Click on this item to select the column in the general data sheet into which the computed azimuth-style bearings will be recorded.
  ! Any existing data in this selected column will be overwritten.
  The azimuth bearings will be listed as positive values read clockwise from North (i.e. north = 0 or 360, east = 90, south = 180, west = 270, etc.).
Decimals: Specify here the number of decimal places to be used in the output coordinates. This should probably match the accuracy of the input coordinates.

Step-by-Step Summary

Access the RockWorks Utilities program tab.
Open or create a data file containing the listing of quadrant-style bearings to be translated.
Select the Utilities | Coords | Quadrant -> Azimuth menu option.
Enter the requested menu items, described above.
Click the Process button to continue.

The program will translate the quadrant-style bearings into decimal-style azimuth bearings and store them in the selected column in the datasheet.

Below are some examples of the quadrant-to-azimuth translation with the output coordinates set to 2 decimal places.
