What is the formula for calculating the distance on the ground using Engineering Scale (ES)?
What is the formula for calculating the distance on the ground using Engineering Scale (ES)?
- Distance on ground / ES = Distance on map (correct)
- Distance on map * ES = Distance on ground
- Distance on map / ES = Distance on ground
- Distance on ground * ES = Distance on map
Which type of map scale provides more detailed maps for a smaller area?
Which type of map scale provides more detailed maps for a smaller area?
- Engineering Scale (ES) (correct)
- Representative Fraction (RF)
- Hydrographic Scale
- Graphical Scale
What is the purpose of using Representative Fraction (RF) for map scale?
What is the purpose of using Representative Fraction (RF) for map scale?
- To eliminate temperature variation errors
- To represent larger areas with less detail (correct)
- To measure under water features
- To provide accurate distance measurement

Study Notes
Mapping and Surveying
- The formula for calculating the distance on the ground using Engineering Scale (ES) is: Distance = (RF x ES) / 12
- Large Scale maps provide more detailed maps for a smaller area
- The purpose of using Representative Fraction (RF) for map scale is to express the ratio of the distance on the map to the corresponding distance on the ground
- The principle of "Check and Verification" aims to prevent accumulation of error and localize error in surveying
- The principle behind using Graphical Scale for distance measurement is that the distance measured on the map is directly proportional to the distance on the ground
