Nearly all navigation is an attempt to join landmarks together. Even those on boats crossing oceans are probably hoping to find a landmark they recognise as the final part of their journey.
The word, ‘landmark’, simply means something that makes a location recognisable. It is deliberately vague as it can apply to anything, a landmark may be extraordinary – the statue of Christ the Redeemer towering over Rio de Janeiro’s from Corcovado mountain. Or it may be mundane – a red postbox at the edge of a village.
The more confident you can be that you have both successfully identified a landmark and that you know exactly where that landmark is, the more confident you can be that you know where you are.

I went for a short walk in the dark last night. The clouds were firing past the moon and jupiter giving a very eery feel as the light levels rose and fell dramatically and the wind tore threw the branches. This rushed picture shows a blurred moon, seen through some branches. The moon and Jupiter were very close to each other last night, near conjunction and a blurred Jupiter can hopefully just be seen below it and to the left, also mired in cloud. One of the branches is close to touching it.
