What are the different types of maps?

According to the ICSM (Intergovernmental Committee on Surveying and Mapping), there are five different types of maps: General Reference, Topographical, Thematic, Navigation Charts and Cadastral Maps and Plans.

What is scale and distance?

Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.

What is difference between spot height and benchmark?

If an elevation is marked on a map, but there is no physical mark on the ground, it is a spot height. The height of a benchmark is calculated relative to the heights of nearby benchmarks in a network extending from a fundamental benchmark. … The position and height of each benchmark is shown on large-scale maps.

What is called a spot height?

A spot height is an exact point on a map with an elevation recorded beside it that represents its height above a given datum.

What are 3 types of maps?

What shows height on a map?

Contours are shown on Ordnance Survey maps as thin orange or brown lines with numbers on them that show you the height above sea level of any point on the line. The contour lines join points of equal height together.

What does a spot height look like?

A spot height shows exact heights by a black dot with a number next to it. The number is the height above sea level in metres. Trig points or Triangulation Pillars are another way of spotting the top of a mountain on a map. … The number beside it shows the height above sea level.

What are the 7 types of maps?

Some of the most common types are political, physical, topographic, climate, economic, and thematic maps.

What are the three uses of maps?

What are the uses of maps showing?

Maps are an essential tool of geography. Maps are a representation of the Earth’s surface. Topographic maps, for example show the location and shape of mountains, valleys, and plains; the networks of streams and rivers; and the principal works of man.

How far apart are contour lines on a map?

A contour is a line drawn on a map that joins points of equal height above sea level. For 1:25 000 scale maps the interval between contours is usually 5 metres, although in mountainous regions it may be 10 metres.

What is the difference between spot height and triangulated height?

TRIANGULATED HEIGHT: It is the height of a place which has been calculated using trigonometry, represented by a small triangle e.g. – Δ540. … SPOT HEIGHT: The height of random places between contours shown with a dot.

What is a spot level?

Each surveyed point taken is referred to as a ‘Spot level’ or ‘Spot height’. That means it is the level at that particular point compared with a datum. To help identify each spot height lower case letters are used.
