Map scale geography. A verbal map scale expands abbreviations to describe a landmark or an object. An example is the image to the left describes a scale as cm is equal to 15 kilometers. One extra types of scale that can be added in geography books.
Maps presenting a large amount of distance such as 1450000cm are difficult to describe. The small scale refers to how small the fraction is. A map showing the entire world would be considered a small scale map whereas a map showing a neighborhood would be considered a large scale map.
Small scale maps tend to show a larger geographic area and less detailed and large scale maps show a smaller geographic area with greater detail. The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. This simple concept is complicated by the curvature of the earths surface which forces scale to vary across a map.
Because of this variation the concept of scale becomes meaningful in two distinct ways. Since maps represent large areas they cannot be drawn the same size as the real area on the ground. Maps are drawn small in comparison but they still give us the actual area they cover on the ground and the same distance between places.
In order to do this a map uses a scale. Accurate maps are therefore normally drawn to scale. A scale is relationship between map distance and actual ground.
A map scale is a ratio of the distance on a map to the actual distance of the ground. Map scales can usually be found on the outer edge of a map usually near the maps key a set of symbols that. In this lesson we discuss the scales used in geography.
Map scales and relative scales. Specifically well look at examples of each and discuss how to use them for travel and research. Maps are often known as large scale or small scalea large scale map refers to one that shows greater detail because the representative fraction eg 125000 is a larger fraction than a small scale map which would have an rf of 1250000 to 17500000.
