Take a Control Point on the Ground

Learn how to create control points from your own position during your journey.

Work in progress

We'll see here very soon a real example of control point creation on the field, in a typical Veezer usage.


For now, let's review the recommendations from the quick start guide:


Improve location with a control point

For optimal accuracy, it is recommended to add one control point per photo.

A control point allows you to improve or verify the location by pointing a reference position on the photo.

A single control point allows for 4 to 6 times more accurate positioning.

Add a control point when you arrive at a location that is easily identifiable in the photo, more than 300 m away (1000 ft).

Identify a reference position

Use your own position as a reference during your journey. You can also directly specify the map coordinates of a position.

Choose a place that is easily identifiable in the photo (rock, tree, summit, pass, building, etc.).

The control point must be at least 300 m (1000 ft) from the photo to obtain good accuracy.

Example of control point:

Control point

The greater the distance, the more accurate the control point will be.

Create a control point

Zoom in on the image to locate your position then tap Create Control Point button (or long-press the photo).

Point the position precisely on the photo.

Check that the GPS accuracy is sufficient.

attention

A bad control point can completely distort the location on the photo.

Validate to create the control point. The location on the photo is immediately updated.
