Key learning points

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

• Elevation Profile - a GIS tool which visualises changes in height above or below sea level along a transect line
