Angle systems
Angle systems category let you define angle systems. The definition includes the unit of the angles, the direction of zero for heading, and the directions of increasing heading, roll, and pitch angles.
A new angle system can be defined by using the Add button in the TerraPhoto Settings dialog. An existing system is modified by selecting the system and using the Edit button. A data click on the Delete button deletes a selected angle system.
This setting category is currently no used by any TerraPhoto functionality.

Name |
Descriptive name for the angle system. |
Unit |
Format of the input angles: •Radians - 2*pi - angle values are given in radians. The software normalizes the values between -pi and +pi. •Degree - 360 - angle values are given in degree. The software normalizes the values between -180 and +180 degree. •Gones - 400 - angle values are given in gones. The software normalizes the values between -200 and +200 gones. |
Heading zero |
Defines the direction where heading is zero: North, East, South or West. |
Heading increase |
Defines the direction of increasing heading values: Clockwise or Counter clockwise. |
Roll increase |
Defines the direction of increasing roll values: Left wing up or Right wing up. |
Pitch increase |
Defines the direction of increasing pitch values: Nose up or Nose down. |
