Scale

Day 6: Scale

Scale allows us to calculate the real distance between two points in a map.

We are going to calculate distance between Seville and Zaragoza using two different techniques:

the first one a graphic scale the second one a numeric scale.

Day 6: Scale

Scale allows us to calculate the real distance between two points in a map.

We are going to calculate distance between Seville and Zaragoza using two different techniques:

Graphic Scale:

Calculate: 4,4x400  = 628km

                    2,8

Numeric Scale:

The numeric scale of this map is E.1:11900000 = 1 cm in the map is 11900000 cm in the real world.

11900000/100000 = 119 km

1 cm in the map is 119 km in the real world

We can We can calculate the distance between two points with this number:

1. We have to measure the distance in our map between Zaragoza and Seville => 5.27 cm.
2. 5.27 cm x 119 km = 628 km between Seville and Zaragoza.
