I need to calculate the straight-line distances between three specific UK locations: Buckingham Palace (SW1A 1AA), Edinburgh Castle (EH1 2NG), and the Giant's Causeway Visitor Centre (BT57 8SU). First, add these points to the map using their postcodes. Then, navigate to the 'Distance Matrix' and provide the distances between all three points in miles. Finally, confirm if the tool calculates road distances or only straight-line distances.
Navigate to gridreferencefinder.com. Add Buckingham Palace using its postcode 'SW1A 1AA'. Add Edinburgh Castle using its postcode 'EH1 2NG'. Add Giant's Causeway Visitor Centre using its postcode 'BT57 8SU'. Click on the 'Distance Matrix' link (ID 173). Change the distance units to 'Imperial' (miles) using the dropdown (ID 128). Extract the straight-line distances between all three points from the displayed matrix. Determine if there is an option to calculate road distances instead of straight-line distances. Summarize the distances and confirm the type of distance calculation.
The agent successfully adds all three specified locations to the map. The agent successfully navigates to the 'Distance Matrix' page. The agent successfully changes the distance units to miles. The agent provides the correct straight-line distances in miles between: Buckingham Palace and Edinburgh Castle, Buckingham Palace and Giant's Causeway Visitor Centre, and Edinburgh Castle and Giant's Causeway Visitor Centre (exact values may vary slightly based on precise postcode mapping, but should be within a reasonable range, e.g., ~330-340 miles, ~300-310 miles, ~130-140 miles respectively). The agent correctly states that the tool only calculates straight-line distances and does not offer an option for road distances.
