When making a Measurement, you are making registrations. Depending on the mode, the required number of measurements can be fixed, or open-ended. An open-ended measurement mode requires the user to close the Measurement manually (usually by double-clicking on the last measurement). | When making a Measurement, you are making registrations.

A Signal can be best described as an event emitter. Signals are provided throughout the SDK to cover different use-cases where your integration will want to be notified of certain events. | A Signal can be best described as an event emitter.

One example of such an option is the "CRS" option. This setting can be used to provide the CRS to be used by the SDK when returning spatial data. The full list of options can be found in the [[https://orbitgt.com/kb/developer/sdk_reference_docs|reference documentation]] (startup options have a STARTUP_ prefix). | One example of such an option is the "CRS" option.

| ==== Tilt Angle ==== |
| |
| The viewing direction of a view in the vertical plane parallel to the viewing direction. Zero degrees indicates the view is looking at the horizon and 90 degrees indicates the view is looking up. Tilt is similar to the concept of pitch in navigation. |
