OS OpenData interactive postcode viewer

We recently wrote about the work of our on our summer interns in our Labs team, Joseph Braybrook, creating a Minecraft map of Great Britain. During his time with us Joseph also created an interactive postcode viewer for exploring all 1.7 million postcodes in Great Britain.

We decided it would be interesting to try the same approach using British postcodes, which are readily available as open data in our Code-Point Open product. This is a much larger dataset with almost 1.7 million individual records.

To further showcase what can be achieved with OS OpenData we also incorporated some of our mapping in the form of OS VectorMap District.
