The extent of reduction needed to display a representation of the Earth's surface on a map. A statement of a measure on the map and the equivalent measure on the Earth's surface, often expressed as an representative fraction of distance, such as 1:24,000 (one unit in the map equals 24,000 units on the ground).

The relationship between distances on a map and the corresponding distances on the earth's surface expressed as a fraction (constant for a given map).

(3) A rate that compares the distance between two locations on a map with the actual distance between them. The rate is often represented by a labeled line segment, similar to a ruler.

a representation of distance on a map or globe

A ratio that compares the distance on a map to the actual distance between two locations. The ratio is often represented by a labeled line segment.

details how large an area the map covers. The larger the scale the more the map covers. Eg. 1:10,000 - 1 cm on the map equals 10,000 cm in the field (100 metres). 1:50,000 - 1 cm on the map equals 50,000 cm in the field or 500 metres.

a ratio representing the relationship between a specified distance on a map and the actual distance on the ground

a ratio that expresses the relationship between distances on the map and corresponding distances in the real world

a representation of the ratio between a measurement of distance on a map to the same distance in the real world

used to show distance on a map

The scale of a map is the ratio between the distance between two points found on the map as compared to the actual distance between these points in the real world.

The relationship existing between a distance on a map and the corresponding distance on the earth. A scale of 1 inch = 2000 feet can also be expressed as 1:24,000 (i.e., 1 inch on the map to 24,000 inches on the earth).

used to measure distance between places on a map

The measure of reduction between the representation and the reality, be it a map or a spatial database. Scale is usually represented as a representative fraction of distance e.g. 1:50,000, one unit of distance on the map representing fifty thousand units in reality. The nominal scale of a spatial data set has considerable influence over the possible application of the data set, and you should always be aware of any such implications. For example, it would not be sensible to compare the shape of a road represented in a 1:625 000 scale data set with one of 1:1250. Theoretically, a dataset does not have a scale (unlike a map) but the terms Scale is usually used as a metaphor for resolution and content.

The reduction needed to display a representation of the Earth's surface on a map. A statement of a measure on the map and the equivalent measure on the Earth's surface, often expressed as a representative fraction of distance, such as 1:10,000 (one unit of distance on the map represents 10,000 of the same units of distance on the Earth).

Scale indicating distances in miles on the background map. The scale changes as the user changes the area displayed in the map viewer.

The relationship that exists between the distance measured on a map and the corresponding distance measured on the earth's surface.

The relationship between distance on a map and the corresponding distance on the earth's surface. Map scale is often recorded as a representative fraction such as 1:1,000,000 (1 unit on the map represents a million units on the earth's surface) or 1:24,000 ( 1 unit on the map represents 24,000 units on the earth's surface). The terms "large" and small refer to the relative magnitude of the representative fraction. Since 1/1,000,000 is a smaller fraction than 1/24,000, the former is said to be a smaller scale. Small scales are often used to map large areas because each map unit covers a larger earth distance. Large-scale maps are employed for detailed maps of smaller areas.

A key that provides equivalence between a distance on a map and the associated real-world distance.
