Draw Center Pivot Irrigators

WMC Map allows you to draw full circle and part-circle center-pivot irrigators.

  1. Click on the New button ‘New’ button at the top of the screen, then click on ‘Centre-Pivot Layer’
  2. You will notice a new layer called “New Pivot Layer” appears at the top of the layer tree. Click on the text that says “New Pivot Layer” to make it selected (it will turn blue).
  3. Click on Edit button ‘Edit’ then Add button ‘Add’.
  4. Click in the position you want to place the center of your pivot. (You can move it later, so don’t need to place it too accurately to start).
  5. A window will appear asking you to enter some information about your irrigator.
    1. Enter a start angle of 0 and end angle of 360 to draw a full circle pivot.
    2. Enter wheel track radii (distance from center) to draw in wheel tracks. Enter radius and then click on “Add value”. Repeat this process for each tower.
      1. A handy tip is to put a wheel track at 2m (or 7’) so that you can see where the centre-point of your pivot is.
    3. Sprinkler tracks and endgun radius is optional.
    4. Click OK to create your irrigator.
  6. To move your irrigator, click on move_button ‘Move’ then move your mouse to the centre of your pivot, then downwards until you see the cursor change to a pen with a black dot Pen cursor. Click and drag to move your irrigator.
  7. To modify the specs of your irrigator, click on Select button ‘Select’ and then click on the centre of the irrigator you wish to edit.
