In Dec 2015 the BBC reported on Britain’s busiest and quietest stations. They made use of data released by the Office of Rail and Road (ORR) that records the estimated number of entries and exits based on the total number of people traveling from or to the station. The list of busiest stations in the BBC article isn’t particularly surprising – London’s main stations are by far the busiest (Waterloo, Victoria, Liverpool Street, etc).
What is more interesting to me is the year-on-year change for each station – whether usage significantly increased or decreased – and seeing this information on a map where it belongs. The ORR publish a time series dataset for 1997-2015 that includes Ordnance Survey grid references. This makes it an easy job to plot the location of the 2,608 stations in InstantAtlas.
My report shows year-on-year change. One challenge was the large number of points (stations) that obscured one another and made the map hard to read. To overcome this I filtered out stations where year-on-year change was less than 50% and experimented with the size, colour and opacity of the points to strike the best balance.

Note that the 2003-04 date carries a * flag. The ORR did not provide estimates for 2003-04 and so estimates for this year were calculated as the average of the years to either side.
The National Assembly for Wales is a democratically elected body which represents the interests of Wales and its people. As well as making laws it also holds the Welsh Government to account. One of its most important roles is to examine what the government does, asking detailed questions about its actions and policies.
The Research Service provides expert and impartial research and information to support Assembly Members and committees in their work. To help them do this effectively, the Research Service wanted to provide a self-service programme which would enable Members and their support staff to access statistics about their particular area by constituency. We spoke to Sam Jones from the Assembly Research Service about the importance of the programme and how InstantAtlas software was used.
The Instituto Aragonés de Ciencias de la Salud (Aragon Health Sciences Institute) is responsible for research and knowledge management in Biomedicine and Health Sciences for the public health system in Aragon. Its purpose is to help drive innovation and improvement in health services through knowledge management.
Which project initially sparked your interest in data visualization?
We were working on an atlas of variation in medical practice in the national health system based on the academic work behind the Dartmouth Atlas of Health Care. Our aim was to map unwarranted variation in medical practice.
With global warming high on the international political agenda, mapping software has for the first time been used to reveal the state of health of the global population of snowmen. The new atlas shows how global warming has had an impact on numbers and population health.
According to NASA’s Goddard Institute for Space Studies, average temperatures have climbed 0.8 degree Celsius around the world since 1880, much of this in recent decades. The 10 warmest years in the 134-year record all have occurred since 2000, with the exception of 1998. 2014 ranks as the warmest on record and the Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.
A Happy Christmas and a Happy New Year from all of the InstantAtlas team.
The Office of Statewide Initiatives at the University of Nevada School of Medicine collects a range of data covering population, poverty, health, workforce, and access to health for the 17 counties in the state. The data has been previously published in seven editions of the Nevada Rural and Frontier Health Data Book. The Data Book now has an online version with the Nevada Instant Atlas using online mapping software. We spoke to Tabor Griswold, PhD, health services research analyst, about the new atlas and making population health data more accessible to the public.
How did you find out about InstantAtlas?
I attended the Esri International User’s Conference and saw a presentation by the Louisiana Department of Health and Hospitals on its atlas. I have been collecting health data since 2004 and it has been a long-held objective to create an online version. However, the cost of and or programming a website was more involvement than I wanted and InstantAtlas seemed like a reasonably-priced solution.
We spoke to Tim Carpenter East Sussex in Figures (ESiF) Co-ordinator, Research and Information at the council about the latest developments.
East Sussex in Figures is a website providing the latest statistics on the social, economic and demographic character of East Sussex and its communities. The team at East Sussex County Council has been using InstantAtlas for several years and recently created a new atlas that allows users to call up areas of deprivation within the county and to interpret the data in a geo-spatial way. We spoke to Tim Carpenter East Sussex in Figures (ESiF) Co-ordinator, Research and Information at the council about the latest developments.
Why did you create the new atlas?
It started with a presentation that we did to the members of the chief executive’s department about Indices of Multiple Deprivation (IMDs). The indices are used widely to analyse patterns of deprivation and to identify areas that would benefit from and are eligible for special initiatives or programmes. They are key to releasing funding for projects, from road schemes to new playground equipment and are useful for everyone from parish councils to county councils. In the past, bespoke reports and research on deprivation were carried out as and when required using ArcGIS. So we decided to create a new atlas to provide users with tools to carry out their own research without requiring specific GIS knowledge or skills.
What does the new atlas show?
It gives a much more realistic picture of deprivation and also gives a sense of geographical space for the users. The challenge we have in East Sussex is that it is mainly a rural county with a low population density away from the coast and so any visual analysis by Lower Super Output Area (LSOA) alone will not give a representative image of deprivation in the county.
The detail provided by the background mapping makes identifying neighbourhoods much more effective without removing the visual impact of the standard deprivation yellow to blue colour scheme. Users can map each domain and the filters allow user to look at specific geographical areas within the county (districts and parishes etc.) and create a custom deprivation profile for this area.
Who is using the atlas?
We get many queries on deprivation from councillors, colleagues, third sector organisations and residents asking us to tell them about levels of deprivation in the areas they live, or are responsible for. The addition of a Google interface allows them to search by postcodes or street names and so it really does give them the picture they can understand. In addition, users can filter according to their specific geographical areas or responsibility and create a bespoke deprivation profile. Beforehand this process would have taken around 30 minutes using ArcGIS and would have been a one off process each time a profile was required. It is a great example of a reusable, multi-functional easy to use geographical evidence base.
The Institute of Physics and Engineering in Medicine (IPEM) is the professional organisation for physicists, clinical and biomedical engineers and technologists working in medicine and biology.
The IPEM’s Workforce Intelligence Unit was set up to give it a credible voice in policy development, the training and education of physicists, engineers and associated services working in all areas of medicine and healthcare. As a leading centre for workforce intelligence the IPEM is able to map demographic, health and services information, across the four countries of the UK, and overlay workforce information. We spoke to Jemimah Eve, Project Officer, about mapping software and how it is being used to meet IPEM’s objectives.
When did you first come across InstantAtlas?
I saw Public Health England’s Atlas of Variation and realised it was a good way to get information into the hands of people who don’t have a detailed knowledge of html or GiS systems…
