Mastering Grid References for Mapping Success

This video tutorial explains grid references, focusing on their use in Ordnance Survey maps. It covers the basics of eastings and northings, and how to use four-figure and six-figure grid references to locate features on a map. Practical examples and tips are provided to help viewers understand how to apply these concepts, including dealing with map symbols and ensuring precision in identifying locations.
