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.
Used to take distance measurements from point ―A‖ to point ―B‖ on maps; in conjunction with the distance bar scales on the map. NOTE. When used on a 1:50,000 map, each tick mark on the edge represents 100 meters (107 yards) of ground distance. ZERO.
Measure Distance on a Military Map. A graphic scale is a ruler printed on the map and is used to convert distances on the map to actual ground distances. The graphic scale is divided into two parts. To the right of the zero, the scale is marked in full units of measure and is called the primary scale.
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.
Used to take distance measurements from point “A” to point “B” on maps; in conjunction with the distance bar scales on the map. NOTE. When used on a 1:50,000 map, each tick mark on the edge represents 100 meters (107 yards) of ground distance. ZERO.
The distance between two points is determinate by measuring between points on the map and multiplying the map measurement by the denominator of the RF. 34 DIRECTIONS Direction- is defined as an imaginary straight line on map or ground and expressed as unit of angular measure.
