Adding an Area

To add an area to the map, ensure you are in Edit mode. For more information please see: Edit Mode.

  1. Click the Add Area button:

  2. This will open the Add Area dialog:

  3. Choose a name that is meaningful for the situation:

  4. You can then choose if the area is a Perimeter or not. If selected, the area will be drawn by default in yellow and will be used to mask areas. If not selected, then the area will only be displayed as a border without infill.

  5. Next, decide if the area is an obstruction that the radar cannot see past, for example, a building. If selected, the area will not be used when calculating the line-of-sight for radars. Please see Trace.

  6. You can then choose to create the area automatically by clicking Create - this will create a default square area.

  7. If you click Create:

  8. You can then edit the default area into the desired shape by following steps 5 and 6 in Areas.

  9. Alternatively, you can draw the area yourself by selecting Draw Area:

  10. The mouse cursor will change to a cross hair.  To draw the area, simply click the mouse to plot points on the map. Note: it is easier to plot the points if you zoom into the area:

  11. Continue to click on points around the obstruction:

  12. To finish the area, place your mouse cursor over the first point and press the left mouse button. This will 'close' the area and finish the drawing process. Once finished, the area is automatically selected, and you can drag it around the map, and also add and remove points:

  13. Click Save to save the area.

To add extra points to an existing area, drag one of the semi-transparent white circles on the edge of the polygon. The polygon will alter shape. To delete a point that you have accidentally added, right-click the mouse button over the point and it will disappear.

If when adding an area, you realise there has been a mistake, click the ESC key and the editing will be cancelled without an area being drawn.

  3. You can select whether the polyline will be an obstruction (which effects Trace Trace). You can then choose to either create a default polyline automatically by clicking Create:

  4. You can then edit the default area into the desired shape by following steps 4 to 7 in Polylines.

  5. Alternatively, you can draw the polyline yourself by selecting Draw Polyline:

  6. If you select Draw Polyline, the mouse cursor will change to a cross hair. To draw the polyline, click the mouse to plot points on the map. Note: it is easier to plot the points if you zoom into the area using your mouse:

  7. Continue to plot your points. Note: you can use the map navigation controls to move the map around if needed:
