Study Notes
Distance Measurement Terms
- The term "linear distance" refers to the distance between two locations along a straight line on a map.
- "As the crow flies" is a phrase used to describe the shortest path between two points, disregarding any physical obstacles.
Purpose of Measuring Distances
- Measuring straight-line distances helps in estimating travel times and planning routes efficiently.
- It provides a baseline for understanding distances that can be adjusted for real-world travel considerations.
Obstacles to Straight-Line Travel
- Natural barriers, such as rivers, mountains, and forests, can impede direct travel routes.
- Urban infrastructure, including roads, buildings, and traffic constraints, often forces detours from a straight path.
Map Measurement Conversion
- A map scale is used to translate measurements from the map to real-world distances.
- By employing the scale ratio, one can accurately determine how distance on the map corresponds to actual distance on the ground.
