Description

The current scale of the ARMap. MapScale is the relationship between the dimensions of features on the ARMap 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 ARMap 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
