Remarks
MapScale is the relationship between the dimensions of features on a map and the geographic objects they represent on the earth, commonly expressed as a fraction or a ratio. A MapScale of 1/100,000 or 1:100,000 means that one unit of measure on the map equals 100,000 of the same units on the earth. Some common scales are as follows:
- 1:10,000 - large scale street level mapping
- 1:25,000 - large scale for topographical and leisure mapping
- 1:50,000 - large scale for topographical and leisure mapping
- 1:63,360 1 inch = 1 mile
- 1:500,000 - small scale state level mapping
- 1:2,000,000 - small scale national level mapping
