The GeoDataViz team’s favourite maps of 2019

Mappy New Year! 2019 was a great year for cartography, especially geo data visualisation. We loved seeing such amazing maps and visuals being produced by some very talented people, and the standard just seems to be getting better and better. Inspired by all the brilliant work we’ve seen, we thought we’d pull together some of our favourites. There are too many to include so this list is by no means exhaustive, but we hope you enjoy our picks.

Surfing Saco Bay, Margot Carpenter

Created by independent cartographer Margot Carpenter, this stunning map depicts Maine’s Saco Bay. The detail is incredible, and we love how the map focuses on the bay’s underwater topography and wave dynamics and how they fuel the bays amazing surfing conditions. There is also a beautiful compass rose that illustrates wave height and a visualisation depicting how bathymetry and waves create surf!

Britain’s most complex motorway junctions 

By Lucie Woellenstein, Graduate Data Scientist 

Did you know that there are 50 motorways in Great Britain with over 8,300 km of roads and a whopping 666 junctions? How many junctions have you takenOr will you be taking as you head off for the summer holidays? Ever tried to come off a motorway junction, only to find you’ve taken the wrong exit and are now heading in the wrong direction? Maybe you’ve driven through the famous ‘Spaghetti Junction’ in Birmingham, and wondered what it looks like from above? Or perhaps you’ve been perplexed at how the most complex of junctions somehow actually work?  

Well here at Ordnance Survey, weve spent many hours over the years thinking about the interwoven laces of motorway junctionsNot from the perspective of a driver, but that of a cartographer. From data architects conceptually modelling how to capture data, to surveyors capturing the exact GPS locations of our roads, and to the cartographers that digitise the maps you use to travel along the motorways – a lot of thought goes into how to cartographically represent junctions in a way they make sense to the map reader.

Tutorial – visualising data in Tableau with the RNLI

So far, we have looked at visualising Royal National Lifeboat Institute and Ordnance Survey data using QGIS and Kepler software. In this, our third technical blog, we will be using Tableau.

Tableau is a data visualisation software that is used for creating a wide range of different visualisation to interactively present data and obtain insights. It has a very intuitive user interface and you don’t need any coding knowledge to work with it. For this tutorial we will be using Tableau Public which can be downloaded here.

We will be creating a spider map or origin-destination map that shows paths between our origins (RNLI stations) and destinations (call-outs). All the data you will need for this tutorial can be found here.

Within this data folder there is a CSV file called tableau_finished which was created using a combination of the RNLI_Return_of_Service_20082006.csv and RNLI_Lifeboat_Station_Locations.csv. Read More

Tutorial – visualising data in Kepler with the RNLI

On 28 February 1823, Sir William Hillary made an impassioned appeal to the nation, calling for a service dedicated to saving lives at sea. That service was to become the Royal National Lifeboat Institution (RNLI).

Did you know?

  • There are 238 lifeboat stations around the coasts of Great Britain, Ireland, the Isle of Man and Channel Islands.
  • Tower Lifeboat Station on the River Thames in London is the RNLI’s busiest.
  • There are 349 lifeboats in the RNLI fleet.
  • The RNLI have 4,966 volunteers.
  • It cost £176.5m to run the RNLI in 2017.

Last week we looked at using QGIS to create some visualisations using data from the Royal National Lifeboat Institution (RNLI) and Ordnance Survey. This week we will be taking the same datasets and working with them within Kepler, Uber’s new open source geospatial analysis tool.

KEPLER (Pt 1)

Kepler is great for creating a range of different visualisations easily and quickly, and to begin with we are going to look at creating a visualisation depicting where in the UK most emergency call-outs are made. To do this we will need to download the RNLI Return of Service data.

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.

Final Geovation Masterclass workshop announced!

A few weeks ago, we announced news that our Geovation team were embarking on a national series of hands-on introductory workshops about visualising with geographic data. With sessions having already been held in Edinburgh, Birmingham and Manchester, next week’s session in Bristol has sold out! Today, we can share details of our fifth and final date of the mini-series. Remember – it’s FREE to attend!

Teaming up with Innovation Point and the Barclays Eagle Lab, we are bringing the class to Cardiff on Tuesday 7 August.

Learn how to design your own map at a Geovation Masterclass

Geovation is holding a series of hands-on introductory workshops to teach attendees the principles of visualising with geographic data. As all tickets were snapped up for both our London HQ and Edinburgh sessions, we’ve decided to run four more events around GB over the next few weeks. Disclaimer – these events are FREE to attend!
