prize7-9, Exercise 2: One neighbourhood on three digital maps

Model answer (method; the differences depend on your area and the services you use):

1. Choose a small area you know well: a few streets, a park and a shopping parade.
2. Open it on three sources, such as a commercial web map, OpenStreetMap and an Ordnance Survey online viewer (or a satellite image).
3. Make a table with these rows: roads and paths; footpaths and cut-throughs; buildings (shapes, names); shops and services; green space; labels and fonts; things missing; things that are out of date.
4. Record the differences. Typical findings: one map shows small paths that another lacks; shop names differ in age; labels appear at different zoom levels; a building is missing on one.
5. Conclude: say which map you would trust for which purpose (driving, walking, planning), and what you would check on the ground.

Point to make: each map reflects choices about data sources, update frequency and what is worth showing.
