Seen several times from nearby, so this position is a good one.
The amber lines join the most recent sighting positions to one another. Where many of them cross is the part of the map most consistent with every sighting at once, which is usually nearer the hardware than any single drive-by fix — but it is a reading aid, not a measurement. Uncheck “Cross-reference lines” on the map to hide them.
