New poster to celebrate 70 years of Britain’s National Parks

Creating a poster of Britain’s National Parks

Joe Harrison in our GeoDataViz team created the beautiful artwork, building on his experience of creating the Great Britain’s islands poster last year. The poster was produced using a variety of software, including PostGIS, ArcMap, Blender, QGIS and Adobe Photoshop. We used a range of our data to showcase the National Parks, including OS Terrain 5, OS Open Zoomstack and OS MasterMap Topography Layer.

Joe’s process for creating the National Park images was inspired by Daniel Huffman at SomethingAboutMaps. It contains a step-by-step guide on how to create shaded relief in Blender. The steps were:

• Clip the OS Terrain 5 raster to OS Open Zoomstack national park polygons using PostGIS. This helps us show the heights of the parks.
• Process the OS Terrain 5 raster using ArcMap.
• Generate hillshades from the processed Terrain 5 raster using Blender, to create the 3D surface of the parks.
• Create terrain style with OS Terrain 5 and surface water from OS MasterMap Topography Layer using QGIS.
• Compile the terrain styles and hillshades with Adobe Photoshop.

Once each National Park was finished, it was a matter of lining each one up for the poster. The parks are ordered by the year they were created, from the Peak District in 1951 down to the South Downs in 2010.

Largest parks:

1. Cairngorms (4528 km2)
2. Lake District (2362 km2)
3. Yorkshire Dales (2179 km2)

Most densely populated parks:

1. South Downs
2. New Forest
3. Pembrokeshire Coast

Highest points:

1. Cairngorms, Ben Macdui, 1309 m
