How do I get compass bearing for a line segment

Discussion created by dtewksbu on Nov 30, 2011
Searching for how to do this brought up an old (2004) forum discussion & thought I'd update for others who need to do this.

If working in ArcGIS10 try EasyCalculate10 (http://www.ian-ko.com/free/EC10/EC10_main.htm). This tool not only generates a column with bearings for line segments in the attribute table, it can calculate many other line attributes as well. There is also a set of plug in formulas for the Field Calculator for use with ArcGIS 9.X (http://www.ian-ko.com/free/free_arcgis.htm)

Worked well on test file and on shapefile with over 3000 line segments. COGO reports in COGO toolbar (editor and info license levels) will give bearing of a line segment, but the individual segment must be selected and informaiton is simply displayed in a dialog box. With EasyCalculate the information is added to the attribute table.

Survey Analyst may also be able to do this, but I do not have this extension.

Happy Holiday Season!
