Hano's Edges

I see those rays in the bottom right hand corner of the first two maps in a lot of maps, what are they for?

crackerjake >> That is a good question. Unfortunately, I don't really know. Depending the representation, these rays can help in routing I guess, but for example here: example of rays, I have no ideas.

In my maps, it is for decoration and for helping marines to sail more efficiently. I know, my cartridge is not finished, so there are no scales and no compass rose (it will take place in the meet of all rays).

Compass directions. They help to put the map in the right angle with reality. A map would be useless for orienteering or navigating without them. Often, maps only have the (magnetic) North indicated, but historical maps for navigation always had N, E, S, W; NE, SE, SW, NW; plus the directions between all these. I don't know if modern navigation maps have all of these.

Right... technically, these maps have (clockwise) N, N-NE, NE, E-NE, E, E-SE,SE, S-SE, S, S-SW, SW, W-SW, W, W-NW,NW, N-NW and finally back around to N. Whew... I THINK I got all those right....

Basically. W-NW is More Westerly than North-Westerly, while N-NW is more Northerly than North-Westerly


Though I am in no way a cartography expert, I "expect" where all the points converge is meant to be somewhere on the equator so the East-West line is overlapping the equator.
