Early in 2018 Ordnance Survey (OS) were approached by the Registers of Scotland (RoS) to support their Data Month, an internal event for RoS staff held in March to facilitate the sharing of knowledge and best practice across the business. RoS is the non-ministerial government department responsible for compiling and maintaining 18 public registers. These relate to land, property, and other legal documents and include the Land Register of Scotland and General Register of Sasines.
What is an annotation?
“a note by way of explanation or comment added to a text or diagram.”
Synonyms: notation, comment, footnote; commentary, explanation.
Sometimes referred to as data labels or captions, annotations are often added to charts to add an extra layer of useful information for the reader. Think of it like using a highlighter on a block of written text. We can purposefully guide our readers to view certain aspects of the data that are important.
Why are they so useful?
Annotations can help:
Critique is defined by the Oxford Dictionary as a detailed analysis and assessment of something and in 2010 Judith Tyner released the book Principles of Map Design and included the diagram on the right, defining the map making process.
Map critique plays an important role in the design process and this is for a number of reasons:
- Feedback will improve your map – If you always think you’re right, how do you know for sure your map is actually any good and doing what it is intended?
- It allows you to analyse the way you work – Constructive criticism can lead you away from bad practices and towards good ones. Mistakes can be spotted and you can learn from them.
- It can give you an advantage – Criticism can be information that perhaps no one else has, making your map a better one. This is valuable information and give you an edge amongst your competitors.
The UK Mapping Festival is a unique collaboration between all those who create, distribute, use and enjoy maps in all their forms. Involving professional bodies, learned societies, government agencies, commercial companies, educational bodies, interest groups and enthusiasts, working to put on a series of events over a six-day period during the week of 2–7 September 2018.
A map is a graphical visualisation of the world around us and is made up using a variety of symbols to help us represent that geography.
Maps use symbols to label real-life features and make the maps clearer. With so many features on a map, there would not be enough space to label everything with text.
Symbols can be small pictures, letters, lines or coloured areas to show features like campsites, pubs or bus stations. If you look closely at a map, you will see that it is covered in symbols.
As we start a new year we thought it would be a good time to reflect on 2017 and also look ahead to 2018. 2017 was our first year with the new team name, GeoDataViz, prior to which we had been known as CartoDesign. You can read more about the changes we made and the reasons why here.
Throughout the year we saw and heard an increasing number of things from many others that validated our decision to make these changes to our team. We always want to stay relevant and forward-thinking and we feel that we are really well placed to do this. It was much more than just a change of name for us – more a change of mindset and a new approach to data. We’re now more journalistic and we aim to tell compelling visual stories rather than just map topography. When working through a project we are now asking more questions, challenging requirements, digging deeper and looking for different angles to tease out narratives and insights.
One of our big achievements last year was the release of our GeoDataViz Toolkit (read more about the release here). Our toolkit is a set of resources that will help you communicate your data effectively through the design of compelling visuals. It is something that we developed and used ourselves throughout 2017 and it enabled us to be more efficient and consistent, allowing us to free up time to work on other things.
What is a basemap?
Often referred to as a contextual or backdrop map, a basemap contains reference information used to both orient the viewer and add context to any data that is overlaid. Basemaps come in a variety of types, styles, and scales, from full detail to muted ‘background’ styles.
In this post we want to explore the options available and share some useful tips for presenting your contextual data effectively.
What are the options?
When it comes to choosing a basemap there are many choices available, from creating your own to using a provided service. Let’s look in more detail at some of these options:
Raster maps are images made up of pixels. The content is set and the scale and style are predefined however it is possible to make minor alterations to the look and feel of them. If you’re using a raster basemap then it’s often a good idea to desaturate the colours, reduce the opacity or even convert it to greyscale. This will help your overlays stand out more clearly.
GeoTech masterclasses are a popular series of events organised by the team at our Geovation Hub in Clerkenwell Green, London. These workshops are not to be missed and book up quickly and it was on a chilly November evening that the Hub played host to the GeoDataViz (GDV) team.
Kicking off the session was Charley Glynn who gave an overview of the team and the important role we play within OS. Our role involves making sense of complex data through compelling visuals and we do that through a number of different techniques and using a range of software.
To emphasise this Charley took us on a journey through some of our recent work including our visuals for the CityVerve project and OS Custom Made. You can find out more about our team and the type of work we do here.
Next up was Paul Naylor who introduced the new GeoDataViz toolkit, a set of assets and resources that can help with communicating data effectively through the design of compelling and informative visuals.

We recently held a hackathon with RNLI and Bournemouth Council and are pleased to report first hand that it was awesome! Read on for a flavour of the day, highlights of the successes and to share some of our experiences in organising a hackathon.
Every year, around 190 people drown in UK and Irish waters – half of them didn’t even intend to get wet. Drowning is a problem – and we need to solve it.
This was the premise of the event – a serious and very real problem that requires creativity and innovative ideas to help improve the situation. After months of organisation the hackathon arrived and it turned out to not only be a great day for all in attendance but also a real success with some fantastic ideas coming out of it. Ideas that show real potential and we are now excited to take the best of them forward.
There was a real buzz around the room as the team’s hacked away
