Regular readers of this blog will be familiar with the work of our Cartographic Designers. The team have been posting a variety of articles here since 2013 from reviews of events to sharing helpful resources. The team recently made some changes to the way in which they work and the work that they undertake, including a name change; from Cartographic Design to GeoDataViz.
In this post the team will consider some of the reasons why, and what the changes mean for them, their work and our customers.
This visualisation, which we created in June 2016, was the trigger for us to review our team and led to the changes that we have made subsequently. It was the first time that we had published a geographic visualisation that doesn’t contain any topographic data. We simply plotted the GPS data using colour techniques that help represent the density. This method is much more abstract (possibly considered as more art than science) than our traditional topographic maps but we felt it gave us a more engaging and visually stunning visualisation.
CartoClinic is a simple way to get in touch and get help whether you are having problems with your GI or concerns with your cartography. Made up of Paul Naylor and Charley Glynn from our GeoDataViz team, we can also call on industry experts from both within OS and from our extensive external network.
Last month marked the seven year anniversary of OS OpenData. We have recently shared insights into how our open products are made and how they are being used. In this post we would like to share some of the other activities we undertake to support our open data and support the community of users, including those involved with free and open source software.
The take-up and effective use of our datasets are fundamental to their success. With this in mind we have produced various resources that lower the barrier to entry and make use easier. We also support the community of users in various ways, from sponsorship of events and awards to the release of assets and resources to lower the barriers of entry.
If you are using, or planning to use OS OpenData then you can find help and support here. There are frequently asked questions and a forum for posting questions and keeping up to date with the latest announcements.
Taking visualisations apart to understand how they were made
Have you ever looked at a map (or any data visualisation for that matter) and thought, I wonder how that was made? If so, then a new concept that we’re calling visual deconstructions, could help.
What is a visual deconstruction?
A visual deconstruction is a concept that our GeoDataViz team have created, allowing them to record the styling rules for a given data visualisation. It is made up of a title, a description, a url where relevant, keyword tags, an image, plus the draw order and styling information for each layer of data from which it is compiled.
It is a form of documentation that allows you to quickly reference and recreate styling rules, as well as being able to share it clearly with others. It is also a great way to learn how something is made and therefore is a useful tool for someone designing their own visualisation.
For a better idea, here is a minified version of what a visual deconstruction looks like:
We’re pleased to announce that The British Cartographic Society (BCS) are collecting entries for their 2017 awards. Their range of award categories aims to recognize the very best cartographic work and scholarship from around the globe and entries are welcomed from all areas of the mapping community.
We provide the BCS with an award to encourage excellence in cartographic design and the innovative and exciting use of OS OpenData. Over the years, we have had some excellent entries including this winning entry from Ashley Clough at Parallel in 2013.
Our GeoDataViz team took part in the ‘Late at the library: you are here’ event hosted by the British Library, with demos and displays by OS and the Geovation Hub, amongst other mappy delights. Find out what happened at the event.
Hosting ‘Map Your London’, we came equipped with sharpies and an (almost) blank canvas of London. Our aim was to understand how those living in London visualise their city. How do they navigate? How would they depict Big Ben or 30 St Mary Axe? What names do they use to describe historic and modern landmarks? So, armed with a pen we let them get to work…
A fantastic way to inspire a love of cartography at an early age, have you heard of the Barbara Petchenik Children’s Map Competition 2017? Barbara was a leading cartographer whose work related to children. In her memory, the International Cartographic Association holds a biennial competition.
2015 overall winner: The world in our hands by Pan Sin Yi (aged 15)
Colour is one of the main graphic elements that a cartographer uses to make their map clear to read. Amongst other things we use colour to create familiarity, to differentiate features and to create a clear visual hierarchy. There are many things we can do to the features on our maps to change their appearance and many techniques we can apply to adjust the colours. Adjusting opacity levels and applying blend modes are the two techniques that we will explore in this post and we will look at some examples of how we can use them together to create effective visualisations.
Recently we wrote about a British Cartographic Society (BCS) event hosted at our head office, ‘Better Mapping with QGIS’. The one day event saw a mixture of presentations and an afternoon workshop, led by cartographic and industry experts. The culmination of the workshop was a map challenge and we are now pleased to announce the winner!
Congratulations to Steve Richardson who produced this excellent map showing Indices of Multiple Deprivation in Southampton:

The challenge was to use open data that had been supplied to create a suitable basemap, and then introduce an additional layer from another open source. Mary Spence MBE had earlier introduced the principles of cartographic design and delegates were encouraged to put these into practice when creating their maps.
