# Circular (Hotpoint) ## Route Settings ### Clockwise Aircraft will fly clockwise. ### Start Angle The entry angle of the circle. True north is 0°. The entry waypoint is displayed as 'S' on the map. ### Angle Between Angle between two adjacent photo points. The default value is 20°, which means total photo number is `360/20=18`. ### Max Height **Single Layer：** The height of the last waypoint. From the first waypoint, the flight height of the aircraft will gradually transition from the min height to the max height. **Multiple Layers：** The height of the last layer。 ### Min Height **Single Layer：** The height of the first waypoint. **Multiple Layers：** The height of the first layer. ### Layers Aircraft will fly at multiple vertical layers with the same radius. For example：Sets layers to 3, min height to 50m, max height to 100m. Aircraft will fly circles at the layer of 50m, 75m and 100m, ### Gimbal Mode **Manual：**Gimbal pitch is controllable in the flight. **Custom：**Gimbal pitch will be set to preset value in the flight. ### Trigger Mode #### Safe Aircraft will stop at each waypoint and take photo. #### Fast Aircraft will fly along the circle at constant speed and take photos at distance. ### Heading #### Towards Hotpoint The nose of aircraft will always point to the hotpoint. #### Away from Hotpoint The tail of aircraft will always point to the hotpoint. #### Along circle looing forward The nose of aircraft will always point to speed direction. #### Along circle looing backward The tail of aircraft will always point to speed direction. ### Shoot in Interval Aircraft will take photo at intervals in the fast mode. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
