For example, a RF scale of 1 : 1, means that every one unit on the map is equal to 1, units on the ground. There is no notation of the actual unit type used on a RF scale. Large scale maps show a smaller amount of area with a greater amount of detail. The geographic extent shown on a large scale map is small. A large scaled map expressed as a representative scale would have a smaller number to the right of the ratio. For example, a large scale map could have a RF scale of 1 : 1, Large scale maps are typically used to show neighborhoods, a localize area, small towns, etc.
Small scale maps show a larger geographic area with few details on them. The RF scale of a small scale map would have a much larger number to the right of the colon such as 1 : 1,, Small scale maps are used to show the extent of an entire country, region, or continent.
A map that shows the water network of a small area may show the river as a polygon layer and will show the tributaries of that river. A small scale map covering the area would show that same river as a line feature and the tributaries would be removed a process known as generalization.
The smaller the scale of the map, the less the actual detail of a feature is preserved. Smaller scale maps have river features that have the lines smoothed out whereas a large scale map would show more detail about the twists and turns of that same river. So why not show the same level of detail regardless of the map scale? There are two main reasons. The first reason is the noise level. Showing a lot of detail for features on a small scale map would cause a lot of confusion on the map.

A graphic scale is a bar that has been calibrated to show map distances. When working with any maps that have been enlarged, reduced, or reproduced on a computer monitor, this graphic scale is absolutely essential.
On maps that have been reduced or enlarged by photocopying, the original ratio and written scales are incorrect, since the relationship between map distance and real world distance has been altered.
But if the graphic scale has been enlarged or reduced to the same extent as the map, it is still correct. To explore the concept of scale more fully see the links about map scale at about. Map scales can be divided into two categories, large and small.
Geographers use these concepts differently than many people. From the geographer's perspective, a large scale map shows a limited amount of space and provides a considerable amount of detailed information about that space. Large scale maps might show the location and dimension of all the buildings in a city block or the location of all the churches, social organizations, and bars in an urban neighborhood.
