Key learning points

1. 2D GIS can be used to visualise and configure primary georeferenced data attributes from physical geography fieldwork.
2. 2D GIS visualisations can use attributes including bearing data to create proportional, orientated symbols.
3. 2D GIS visualisations can be time-enabled using temporal data attributes to enhance the visualisation.
4. 2D GIS visualisations of secondary data such as historical maps can be used to support fieldwork enquiry.

Keywords

• Georeferenced - information which has been tied to a particular location (geolocated), using an agreed system such as latitude and longitude

• Attribute - a data value associated with a feature or variable measure (‘field’) in a GIS layer

• Bearing - an angle measured clockwise from north 0° to 359°used to orientate attribute symbols to show direction

• Historical maps - maps from any time in the past which can be compared with more recent maps, used as secondary data
