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.
7 cze 2014 · The procedures involve setting up a laser at a known distance from the object to be measured, measuring the angle between the laser and the top of the object, and using trigonometric functions based on the distance and angle to calculate the height.
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.
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.
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.
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.
