Calculating Declination

Calculating Declination

Top  Previous  Next

Pressing the “Calculate Declination” button brings up the Compass Geographic Calculator. This allows you to calculate the local declination based on the cave location and the date of the survey. To set the declination, the geographic location, elevation, and must be correct. The date is normally taken from the survey heading, so if it is not correct, you should change it in the heading.

 

Location Not Set. If the cave location has not been set in the Project Manager, the Editor will warn you to set the location manually while your calculating the declination. This usually occurs if you did not run the Editor from the Project Manager or you are not working with a Project File. (See the Project Manager help for details on how to create a project file or to set the Base Location for a survey project.)
