Map scale is ALWAYS shown on a map. Shown below is a British M726, 1:50,000 scale map with the ratio and scale lines shown. Estimating and measuring distance. As maps show a grid and have scale lines, it is possible to estimate or measure distances for use on the ground or on a map.
In order to do this, measure the distance from the start point to the edge of the map. The marginal notes give the road distance from the edge of the map to some towns, highways, or junctions off the map.
The measurement of an area calculates and displays the area between three or more points on the map. To start measuring an area: Press the ‘Measure distance’ button (button turns blue)
1. Identify the scale of the map. The map scale is the ratio (1:50,000) of the distance on map (1 inch) relative to the distance on the ground (usually 50,000 inches). 2. Convert a straight-line map distance to miles, meters, or yards using the map's bar scale (Figure 071-329-1008-1). Figure 1. Bar scales.
The scale of the map permits the user to convert distance on the map to distance on the ground or vice versa. The ability to determine distance on a map, as well as on the earth’s surface, is an important factor in planning and executing military missions.
