Lesson Details
Key learning points
- Spatial data can be shown on a map using points, lines and polygons.
- Geographical Information Systems (GIS) create maps that can show many forms of spatial data.
- There are some styles of maps that show spatial data in specific ways.
Common misconception
GIS and long-hand, paper-based mapping have the same value.
While it is very possible to create representations of spatial data on paper using layers of tracing paper over a base map, the real value of GIS is its ability to analyse data quickly and be edited once the map has been digitally created.
