Study Notes
Calculating Ground Distance: Scale & Distance
- Maps use scales to represent distances on the ground.
- Scale is the ratio of distance on a map to the corresponding distance on the ground.
- A scale on a map indicates the amount by which an area has been reduced for representation.
- Scales determine distances between two points and the actual size of an area.
- Scales show the relationship between map distances and ground distances.
Lesson Objectives
- Define the term "scale."
- Identify three ways scales are shown on maps.
- Explain the importance of map scales.
What is a Scale?
- Map scale is the ratio of distance on the map to the actual corresponding distance on the ground.
Importance of a Map Scale
- The scale on a map indicates the reduction of an area on the map.
- A map scale shows the distance between locations and the size of an area on the ground.
- The scale relates map distances to actual ground distances.
Types of Scales
- Ratio Scale: This scale uses numbers to compare distances on a map to distances on the ground. For example, 1:40,000 means 1 cm on the map equals 40,000 cm on the ground.
- Word Scale: This scale expresses the relationship in words. For example, "one centimeter represents one kilometer."
- Linear Scale: This is a line marked with distances, which makes it easy to compare map distances to ground distances. Often has units (like meters or kilometers) on the line.
Identifying Map Scales
- Example 1: "One centimeter represents five kilometers" is a word scale.
- Example 2: 1:400000 is a ratio scale.
- Example 3: A linear scale is a line marked with distances (in kilometers).
