Introductory techniques
Overlaying data on GIS using layers on a base map, is a useful form of presentation and analysis. It allows the pupils’ own data to be shown spatially. A common software to use is Esri’s ArcGIS online – you can sign up for free schools account with Teach with GIS – although other GIS software is available.
Once logged into your account, find the online map viewer. The first stage is to select an appropriate basemap. This will help with displaying data as it will show location, buildings, roads and other points of interest. To do this, on the left-hand side of the map viewer click ‘Basemap’ and scroll to the basemap of choice.
Once a basemap layer is selected you can then add layers of data. A common way to do this is to use Microsoft excel and set up a CSV file. For more information on how to set up a CSV file go to Field Studies Council resources GIS for data collection.
Once created go back to your ArcGIS online map. On the left-hand of the map viewer click ‘Add’ and then ‘Add layer from file’. Follow the menu through and data will be added to your map.
This can then be presented and analysed in variety of ways, like the one shown below.
Teacher Considerations:
- When selecting basemaps there are a variety of options, some simple, some complex and some quirky. Have a look around so you know what will work for your needs.
- When adding data into your CSV file you can use latitude and longitude or post codes or ‘What3words’ as your geolocation.
Mapping technique
In Creative fieldwork 2, the Pedestrian Toolbox is described. This is a method in which the number of features pedestrians use can be classified and counted.
Carry out the Pedestrian Toolbox method and record the number of pedestrian features at a number of different locations. A CSV file could be created and then added to the base map.
This could then be displayed with proportional circles by clicking on the right-hand light side of the map viewer and the ‘Styles’ button. Then adding the field of the number of features under ‘Choose attributes’ and changing the colour and style under ‘Pick a style’.
In the map above, the red and purple areas have been regenerated with a large number of pedestrians being considered in the design process. Specialised cycle paths, large pavements, seating and pedestrian crossings are all features found in these areas.
The green area has not been regenerated. It is a residential area and so heavy footfall does not need to be accommodated as much. There are therefore few features for pedestrians in this area.

The Geographical Association (GA) has worked closely with the Field Studies Council (FSC) to develop these resources.
