They are labeled with the height and with the topes of the figures uphill. A contour labeled 500 is mm above sea level, and every place on that contour is precisely mm above sea level. On a 1: 25, 000 map, they are usually mm apart. If contours are very close together that means the hill is steep. However, is they are wide apart, it has a gentle gradient.
When describing direction, the normal method to use if by taking bearings. If you look at the housing of compass you can see that it has 360 tiny divisions on it. Bearings are one of the useful and the most accurate of describing directions. They are always given as three figures so that they should have O as the first figure if they are less than 100.

Those types of maps include: Route in a scale of 1: 625, 000 which is one of the smallest scales even though the numbers seem so big.
This specific map is suitable for long distances as well as motorway riving. It would be very useful for the armed forces, who might be based in the south and want to do exercises in the Scottish Highlands. Main roads are clearly marked on this map, but there are few small details. Road in a scale of 1: 250, 000 with quite a small scale that is ideal for motoring.

It provides an excellent overview of the lie of the land with fences, road names, field boundaries as well as building names. Regarding cardinal points of the compass there are thirty two of them, however only sixteen of them are normally used in map reading for the description of direction.
