2.4: What does GIS data look like? (1)

Styles

The very simplest advantage that GIS gives in comparison with paper maps is that you can change the appearance of the information to any style you like. In conventional mapping a large amount of time and effort is spent on deciding appropriate colours and styles for the depiction of features, to ensure that the image is as clear and informative as possible. The flexibility of GIS adds an extra dimension to this process: you can change the appearance depending on exactly what message you want to convey.
