Camera Field of View

Camera Field of View

The field of view is the size of the camera’s viewing angle, or the zoom level of the camera. TerraExplorer Pro’s field of view ranges from 15 to 90 degrees, with 53 degrees set as the default.

A wider field of view (larger angle) allows you to see more, with a decreased zoom level. A narrower field of view (smaller angle) allows you to see less, with an increased zoom level. In some cases, you also experience reduced performance of the TerraExplorer Pro application with a field of view less than 53 degrees.

To set the camera’s field of view:
