Tutorial – visualising data in QGIS with the RNLI

In an emergency the importance of location is critical. Knowing the precise whereabouts of an incident can be the difference between life and death.

The Royal National Lifeboat Institution (RNLI) are the charity that saves lives at sea. Responsible for saving over 140,000 lives since their formation in 1824 they work with a dedicated team of volunteers, staff and community fundraisers. They allow us to enjoy our shorelines and water, safe in the knowledge that in an emergency they will be there to assist us.

There is a lot of data behind the lifesaving and in 2017 RNLI teamed up with ESRI to create an open data portal to help share some of this data.

OS Open Zoomstack is no longer just a 3-month trial!

We’ve had such a great response to the trial and received a huge amount of feedback from the users, that we’re going to invest in making OS Open Zoomstack a supported product.

For both the downloads and the API we’ll be developing Alpha versions and continue to make changes based on your feedback. We’ll be doing an alpha release shortly for the various downloads. We’ll also continue supporting the API, and will update this with the new data from the Alpha while we plan the release of a fully supported version in the future. Please note that this may involve changes in the API URL at a minimum.

At this point we would like to say a huge thank you to everyone who has helped us to make this exciting step!

Dynamic hillshade: create realistic terrain visualisations using OS Open Zoomstack

Inspired by the Mapbox blog – Tim Manners in our OS Labs team built this awesome demo application to showcase the dynamic hillshade. The demo includes a widget which enables you to change the light source directly on the client and see the map change in real-time. Tim used our OS Terrain 50 DTM grid dataset to generate a series of Terrain-RGB tiles. These tiles contain elevation data encoded in raster PNG tiles as colour values that can be decoded to raw heights in metres and rendered on the client-side for customisable terrain visualisations. Take a look below for how it appears when combined this with the OS Open Zoomstack Vector Tile API:

Data Month: GeoDataViz

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. Read More

Annotations: adding narrative to your maps

What is an annotation?

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:

8 tips for map critique

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.

GeoDataViz: map symbols

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.

2017: A year in GeoDataViz

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.
