Map and satellite views help you inspect the circuit geometry from different perspectives. Zoom in where the trace is difficult to judge and check several parts of the lap before making large changes.
Imagery is a reference, and the layout visible in it may differ from the layout you intend to use. Identify that layout in the track name or your notes.
If you ask for help with alignment, describe the circuit and the section you are editing. Avoid including private location details in screenshots.
