Was Chester the intended capital of Roman Britain?

Inspired by a previous blog post that re-imagined Winchester as the nation’s capital through mapping, guest blogger John Murray applied this technique to Chester.

There has been much speculation amongst historians and archaeologists on whether Roman Chester (Deva) was intended to be the capital of Britannia.

This was the subject of a BBC Two Timewatch programme (Britain’s Lost Colosseum) from 2005 and, more recently, in Professor Alice Roberts’ Britain’s Most Historic Towns programme about Roman Chester.

During an archaeological dig in 1939, the remains of a substantial elliptical building were discovered immediately to the dextral rear (north west) of the headquarters building (Principia).

The map below shows the approximate location of these buildings. The elliptical building would have been approximately where the present-day Chester Market Hall is located.

Mapping a new island for April Fool’s Day

For April Fool’s Day we challenged one of our most senior and experienced cartographers to create a mythical island for Country Walking magazine. The premise was that this island had been lost to the sea centuries ago, only for it to have now mysteriously risen out of the waves in need of mapping.   

Mark Wolstenholme, in his 34 years at OS, has worked across every series of mapping we have. Here he explains how to produce a fictional island in a short time frame, while making it authentic enough to convince as a prank.

The power of geospatial data in resilience planning and emergency response

The beast from the east dominated headlines this month, with snow causing traffic issues, school closures and disruption across the country. In Cumbria, the depth of the snow and challenging terrain resulted in significant issues accessing some communities. Cumbria’s multi-agency Strategic Co-ordinating Group (SCG), made up of partner agencies, secured military assistance to help access the most isolated communities, many of which had been cut off from all supplies for five days. We were asked to assist the SCG under Mapping for Emergencies (MFE).

One of our technical consultants, Kevin Topping, knows the power of geospatial in these situations only too well. Since joining OS last autumn, Kevin has been working with local resilience teams across England and Wales, showing how geospatial data can help in emergency planning. He ensures that authorities are aware of the data available under the Public Sector Mapping Agreement (PSMA) and how to best make use of it, including calling for extra assistance from OS under MFE.

Making Ordnance Survey into a work of art

The Lakes Ignite programme for 2018 features an OS-inspired work of art called Ordnance Pavilion, paying homage to the trig pillar and the work of OS surveyors in mapping Great Britain. It’s flattering to be an artist’s muse, but we wonder if it’s not the first time OS has inspired an artwork…

Ordnance Pavilion

Created by Studio MUTT, Ordnance Pavilion is an interactive installation in the Langdale Estate in the Lake District. It forms part of Lakes Ignite 2018 which presents six contemporary artworks to celebrate the Lake District’s designation as a World Heritage site. On display between until July 2018, Ordnance Pavilion is a celebration of OS and how our maps have impacted people’s interaction with the landscape.

Analysing urban green spaces with ONS

By Andrew Cooling and Steve Kingston, OS

The Office for National Statistics (ONS), have begun the delivery of a Great Britain-wide natural capital accounting project, gathering insights on urban green spaces and their effect on our social and economic well-being. We’ve been working with ONS on the project, along with Defra, with our GI Consultant Steve Kingston being seconded to the ONS team to provide geospatial analytical support.

The project started with a pilot in the Greater Manchester area, which delivered at the end of 2017. The pilot helped shape the methodology to deliver two parts of the urban ecosystem accounts, estimates of the extent of green space and blue space in urban areas and estimates of the services provided by this nature, such as filtering air pollution and recreational opportunity.

The urban accounts offer a coherent way of looking at the value of green space in urban areas across Britain. The project aims to help both the private and public sectors to value and monitor the extent and condition of nature in the urban environment and recognise the services it provided. The accounts will aid policy makers in prioritising investment and making informed decisions.
