Using Scales
- Use the given scale to estimate traveling distances when a distance table or distance markers are not provided
- Two types of scale calculations:
- Type 1: Map Measurement to Actual Distance
- Measure a distance on a map
- Use the given scale to convert this measurement to the actual distance
- Formula: Actual Distance = Map Measurement × Scale Factor
- Type 2: Actual Distance to Map Measurement
- Start with a known actual distance
- Use the given scale to convert this actual distance to the map measurement
- Formula: Map Measurement = Actual Distance ÷ Scale Factor
- Type 1: Map Measurement to Actual Distance
Types of Scales
Number Scale
- Expressed in the format 1:50,000
- Conversion is straightforward: enlarge or reduce by the scale factor
- A number scale shows a specific relationship between the size of the area on the map and the actual size of that area
Bar Scale
- Shows the relationship between measured length and actual distance
- Measuring with a ruler on the bar scale shows how many measured units are equal to actual distance
- Different from a number scale in that it does not state how many times smaller the map is from the actual size, but rather how many measured units are equal to a specific number of actual units
