Flightplan Wizard : Define Area to Cover

Defining the area to cover is done in a few steps :

  1. Move to the area in interest
  2. Draw a “construction line” that can be used as strip orientation.
  3. Define an area to fly.

Define Strip Orientation

Define the strip orientation by using the construction line function.

Select the strip orientation line feature

Create the line by selectiong two points.
As a result you will see a blue line representing the strip orientation:

Rectangular Areas

To define a rectangular area:

  1. first delete the previsously created area using :orbitgis:coverage:delete_fence_area.jpg
  2. press the second button and define the area by creating a rectangle that will be exactly parallel to the given strip orientation.

Define a rectangle area.

Select the first point and drag the mouse while the left mouse button is pressed to define the rectangle.

If you made a very small area by mistake, please clear that area first before continuing the creation of a new area. It is prohibited to have more than one area defined for further calculations.

Clearing

To recreate the strip orientation or coverage area use the next buttons to delete

Delete Strip Orientation or Area.

It is especially important to remove all areas when re-creating the area to fly. Having multiple areas will lead problems because they will all be used. When areas overlap, they effectively create gaps.
