How To: Divide a circle polygon feature into segments of a specific angle in ArcMap
A circle polygon can be divided into segments by using the Cut Polygon tool in an edit session. To get a specific angle in each cut, a line feature is created to project the lines needed to be traced with the specific angle.
After using the Cut Polygon tool , the circle polygon can be divided by tracing along the line feature, set to a specific angle.
Instructions provided describe how to divide a circle polygon feature into segments of a specific angle in ArcMap:
- Start Arcmap.
- Find the centroid of the circle feature class, and note the center X and Y coordinates. For more information, refer to the following article: HowTo: Calculate feature centroids.
- Create a new file geodatabase under the desired folder connection; right-click the desired folder: New > File Geodatabase.
- Create a new table in the newly created file geodatabase; right-click the file geodatabase: New > Table.
- Create four fields in the table: distance, bearing, latitude, and longitude, and click Finish.
- Start an edit session on the table, and insert the values. Use the same value for distance, and use the X and Y values from step 2 for latitude and longitude, respectively. Specify the bearing values in an increasing order with the desired interval.
- Navigate to ArcToolbox, Data Managements Tools: Features > Bearing Distance To Line.
- Complete the required fields accordingly, with reference to the previous table in the Bearing Distance To Line tool window. Ensure the Bearing Units field is set to DEGREES.
- Start an edit session on the desired polygon feature, and select the Cut Polygons tool .
- Trace the line accordingly with the line feature created in step 7-8. The polygon is now divided to the desired specific angle.
