1. Identify the scale of the map. The map scale is the ratio (1:50,000) of the distance on the map (1 inch) compared to the distance on the ground. (usually 50,000 inches). 2. Convert a straight-line map. distance to miles, meters, or yards.

7 lis 2013 · PART 1 Basic Land Navigation Map Information - Distance • • EXAMPLE - a map scale of 1:25,000 means that one unit of measure on the map is equal to 25,000 units of the same measure on the ground. – On map 1 inch = 25,000 inches (2083 feet, 694 yards) on the ground.
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.

30 paź 2014 · This document explains how to use a map scale to measure distances. It provides instructions on using a ruler or piece of paper to follow a route on a map and measure the distance in centimeters. The distance must then be converted to kilometers using the scale ratio shown on the map.
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.
