   2. Type in the "Opacity" value to choose the non-transparency percentage of the final colour.

      • 0% is invisible.
      • 50% is see-through.

Configure the circle

5. At the top of the Layers Panel, click on the Gear Icon displaying the tooltip: "Operations and Analysis".
   The Operations and Analysis window will open.
    
6. Under the "Create" heading > "Circle" subheading, click on the link: "At Point".
    
7. (Optional) Under the heading, "Title", type in the name of the circle.
    
8. Under the heading, "Middle LatLng", there are fields on the left and right.
   Type the latitude coordinate into the left field.
   Type the longitude coordinate into the right field.
   Note: The coordinates must be in the format: Decimal Degrees (DD). For example; New York City
   • Lat = 40.730610
   • Lng = -73.935242
    
9. Under the "Radius" heading, select the units from the drop-down: "Metres" or "Kilometres".
    
10. In the field, type in the radius distance.

    You can also use the up/down arrows to make fine adjustments.

     
11. Under the Accurate heading, check the box if you want the circle to adjust for accuracy.
    • If Accurate is selected it draws the circle using the projection of the map. In this case, Mercator. Larger circles may appear as though they are stretched vertically.
    • If it is not selected it will use a straight line distance. This option favours visual over accuracy.

Create, view, and edit the circle

12. Click the button: "Create Circle".
     
13. In the pop-up that appears, click "Ok".
     
14. In the top-right corner of the Operations and Analysis window, click on the "X" button.
    In the Layers Panel, you will see the circle. If you write a title, you will see the name of the circle.
     
15. In Map View, you may have to zoom in or out to see the circle.

    To find the circle quickly, click on the centering button on the circle’s row in the Layers Panel. The button is the outlined square with a dot at the center.

     
16. If you select the Edit/Measure Tool in the top toolbar, you can measure, edit, and move the circle.
