There are two ways to describe the distance between feature; point to point, or along a route. Point to point measures the straight line between points. Measuring along a route might be an obvious path, road, or along your planned route.
To measure a straight line between two points:
a. take a piece of paper and place the upper edge on the map so that it touches the two points;
b. mark the points on your paper;
c. clearly indicate you start and finish points;
d. now place the paper on your scale bars; and
e. calculate the distance – in the example below it is 4800m.
To measure along a route (road, trail, stream, etc) between two points:
a. lay a piece of paper along the first section and mark the paper;
b. now pivot the paper until it lays along the second section, mark your piece of paper at the end of the section;
c. repeat this process until you have reached point B; and
d. compare the distance marked on the paper to the bar scale and calculate the distance.
