May seem unneeded but in-game there will be no cursor to show where you are on a map.

so here is a Illustration of how to do it.



Here is a blank map of your rough vicinity, you want to know where you are?




You look what landmarks are to the North of you, what's to the South-east of you and what's to the South-west of you, draw a imaginary triangle, you'll be in the rough centre of the triangle.

This has limitations, that is if the area is a huge plain and there's no landmarks to distinguish within eyesight.

Yes, which will be great if wherever you are going is to the west ;)

True.

Also (dependent on game features) Wind blows mostly in a single direction in a area, I do believe in the UK for example it is a Westerly direction.
