GIS Files 1: Getting to grips with GIS

1.4: Different types of GIS data (3)

Linking data

Here you can see an example of ADDRESS-POINT™ data. This is far removed from the map model of depicting information – this illustration is meant to demonstrate that not all data in a GIS will look like a map. At first glance the sea of dots may not appear particularly useful: ADDRESS-POINT is not a cartographic product, but is designed to be used in conjunction with other layers of information within a GIS application. Use the links below to see how this type of data becomes useful.

ADDRESS-POINT can be used to identify specific properties against a map backdrop or to link to other sources of associated information, like voting wards. Linking information in this way is explained more fully in later section of the GIS files.

In the last section of this introductory chapter we look at how scale is important in GIS.
