## Question

What are the differences between plan and map?

## Short answer

A plan is a large-scale drawing of a small area, ignoring earth's curvature and showing many details. A map is a small-scale representation of a large area, considering curvature, with fewer details and shown by symbols and contours.

## Answer

| Basis | Plan | Map |
|---|---|---|
| Meaning | Graphical representation of a small area drawn to a large scale | Graphical representation of a large area drawn to a small scale |
| Scale | Large (e.g. 1:100 to 1:500) | Small (e.g. 1:25,000, 1:50,000) |
| Curvature of earth | Ignored; area treated as a plane | Considered for big areas |
| Details | Many details with accurate dimensions | Fewer details, shown by symbols |
| Relief | Mostly shown by spot levels | Shown by contours and hachures |
| Use | Buildings, plots, roads | Regions, topography, atlases |

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. A plan is drawn to
   A. a large scale for a small area
   B. a small scale for a large area
   C. no scale
   D. the same scale as an atlas
   Answer: A. Plans cover small areas at large scale; maps cover large areas at small scale. (Key point: Scale)

2. Relief is mostly shown on a plan by
   A. contours and hachures
   B. spot levels
   C. colour only
   D. no relief
   Answer: B. Maps use contours and hachures. (Key point: Relief)

3. Which statement is correct?
   A. Plans show fewer details than maps
   B. Both show identical details
   C. Plans show many accurate details; maps show fewer details using symbols
   D. Maps ignore symbols
   Answer: C. Plans have many details with accurate dimensions. (Key point: Details)
