On the 180 degs latitude but veers of that line to by-pass New Zealand and then back onto 180
No, the international date line is a line of longitude, not latitude.
Depending on the type of map you are referring to, the solid black line could indicate a national boundary. If it is a map of states, it could be a state boundary.
On a topographic map dashed lines can represent boundaries (e.g. national, state, etc). A dashed line can also represent a hiking trail or a telephone, or above-ground oil or gas line.The color and length of the dashes can distinguish between one type and another. Check the map legend to understand the exact meaning.
The two broken lines on a world map are called the International Date Line and the Tropics of Cancer and Capricorn. The International Date Line, located at approximately 180 degrees longitude, serves as the boundary for calendar dates. The Tropics of Cancer and Capricorn mark the northern and southern boundaries of the tropics, indicating the furthest points north and south where the sun can be directly overhead.
The International Date Line is nominally the line of 180 degrees longitude, both east and west ... exactly opposite the Prime Meridian and half-the-earth away from it. The Line was drawn with some jogs and zig-zags in it for political reasons, mainly to avoid having it split island nations or contiguous areas of national interest.
The International Date Line zigzags to accommodate national boundaries and avoid dividing countries in half. It appears on both sides of the map because it is not a straight line; it bends to include certain territories within the same date.
The national boundaries
Usually on a flat map of the world the international date line is the left and right (west and east) edges of the map, but it is clearly marked on a globe.
A national boundry is a thick black line
Depending on the type of map you are referring to, the solid black line could indicate a national boundary. If it is a map of states, it could be a state boundary.
It is known as the International Date Line.
Alaska. A small Alaskan island in the Pacific is the cutoff for the dateline. If you look on a map showing the date line, you'll see the dateline swerves in order to accommodate the US national boundary.
A date on a map could be when the map was surveyed, or published. It could also represent the date of a battle - the site often marked by a cross-sword symbol and the date.
A national border can be represented by a dashed line or a solid line with different colors on each side. A national capital can be represented by a star symbol or simply by the name of the city with a star next to it. A city can be represented by a circle or a dot on a map, often labeled with the city's name.
