Raster styling: A grey area?

Over the last couple of years we have been developing and applying our new corporate map styles which provide visual consistency to our portfolio of digital maps. These new styles have been applied to our OS VectorMap products and stylesheets are supplied for our vector products.

We have developed a full colour style and a backdrop style, with the latter being designed for contextual basemaps that facilitate data overlays. We have applied an element of colour science to ensure that all map features take their place within a clear visual hierarchy whereby the features deemed most important will be perceived first. This means that if you convert our raster products to greyscale, the visual hierarchy is still maintained. 1:10000 TILE SK54SE

British Cartographic Society Symposium 2013

Last month Paul in our Cartographic Design team attended the British Cartographic Society’s (BCS) Annual Symposium entitled Today, Tomorrow and Beyond. 2013 celebrates 50 years of the BCS and to celebrate the symposium was once again held in Leicestershire where the first symposium was held back in 1964. Find out what happened at the event.

The symposium saw a number of cartographic professionals and enthusiasts come together to hear and participate in a range of presentations and workshops. The symposium was officially opened by current President Peter Jones. As part of his opening speech he revealed this year’s ice breaker which was provided by us at Ordnance Survey. The ice breaker was called the The Naked Landscape and involved the identification of 25 different locations using 1:25 000 mapping which had the text and some selected features removed. The prize for winning was a prestigious Ordnance Survey Custom Made map.

Wednesday was the highlight of the symposium and opened with an excellent presentation session on Mapping Technologies for Tomorrow with presentations from Leica Geosystems, United States Geospatial Intelligence Foundation and the UK Hydrographic Office, before moving on to workshops. Paul attended Mapping the Swiss Way led by ESRI Switzerland where they were given a short insight into how the Swiss National Mapping Agency (swisstopo) is using ArcGIS to produce their new 1:25 000 national mapping series.

The 26th International Cartographic Conference

Last week, the beautiful city of Dresden in Saxony, Germany played host to the 26th International Cartographic Conference.

As the conference welcome letter points out, ‘Dresden boasts the highest density of art treasures in Europe. And, for cartographers, the possibility to view one of the top international globe collections. Dresden is also the home of educational and research institutions that have progressed the theoretical and practical elements of Cartography and GI Science.’

Whilst the majority of the population is of German ancestry, the Slavic and Soviet influences along with the city’s geographical location bring a very multicultural feel to the city making it a befitting venue for an international conference.

Ordnance Survey created a significant presence at the conference with three paper presentations, an Ordnance Survey wall in the Cartographic Exhibition, and five posters in the Poster Exhibition, all of which was very much noticed and led to much discussion with peers from field-leaders to new faces.

 

Paper presentations

Our papers, and many of the others, are all on the conference website:

Ordnance Survey’s cartographic design principles: An approach to promoting good map design

C. Wesson, C. Glynn, P. Naylor

Deriving Products from a Multi-Resolution Database using Automated Generalisation at Ordnance Survey

N. Regnauld, S. Lessware, C. Wesson, M. Plews

Identifying Built-up Areas for 2011 Census Outputs

J. Harding, B. South, M. Freeman, S. Zhou, A. Babington

With over 150 presentation sessions, seven plenary keynotes and many other events, presentations, meetings and awards, there was great variety at the conference and yet the majority of the content was also pleasingly very cartographic. Our presenters and attendees all gained far more than they had hoped from the week and we are now feeding this back into the business. Read More

OS OpenData Award – 2013 Winner Revealed

Ordnance Survey sponsors and judges one of the British Cartographic Society (BCS) awards and this was its maiden year as the OS OpenData Award. The award is given annually to encourage excellence in cartographic design and the innovative and exciting use of OS OpenData.

The award is announced and presented at the gala dinner of the annual BCS symposium which was held last night at Hothorpe Hall Hotel in Leicestershire.

Vanessa Lawrence, our Director General, had earlier delivered a keynote speech at the symposium in a special 50th anniversary session that included presentations from the heads of each of the five British mapping and charting agencies.

We are delighted to announce that the winner of the 2013 OS OpenData Award is Parallel. At the ceremony last night, Vanessa presented the award trophy, along with certificate and prize, to the winning entrant Ashley Clough of Parallel.

Parallel are a company creating websites, apps and maps and their award-winning entry is entitled ‘OS OpenData backgrounds and overlays for interactive UK healthcare visualisation’.

It is a contextual web map ‘zoom stack’ in a consistent style with boundary overlays, built using open source tools and the following OS OpenData products: OS VectorMap District, Meridian 2, Strategi, OS Terrain 50 and Boundary-Line. They have also used our Linked Data service for the search tool.

2013 ESRI International User Conference

One of the largest events in the GIS calendar, our Cartographic Design team were represented at the event for the first time when Christopher attended the conference in San Diego from 8–12 July. The event offered the latest updates on what is happening in the world of ESRI software as well as many themed presentation sessions over the five days.

The week began with the plenary session including highlights of what’s new in the ESRI product suite and case studies including Philadelphia Police Department using GIS to match up burglary patterns and addresses of known or suspected criminals and to create predictive maps and hot spots to advise police where best to be deployed for maximum effect. Many of the topics covered in the plenary session have been used in the online GIS of Horry County, some of which has public access.

Sam Pitroda discussing a national GIS model for India during the plenary session

Also in the plenary, Satyanarayan (Sam) Pitroda spoke excellently on GIS development in India. Whilst many of the world’s populations are decreasing and elderly, India’s is young and growing. The challenge, as Dr. Pitroda – advisor to the Indian Government – put it, is to feed them and to train them with the best education possible. Whilst worldwide talent is preoccupied with solving the problems of the rich, in India they are training their own young talent in GIS to help tackle the problems of the poor. He continued to describe how India needs a standard and socially-inclusive method of connectivity, access, organisation, policy and innovation and how all of these are related to GIS.

Unsurprisingly it was Will.i.am and his team of school children who headlined the plenary sessions. He gave an open interview to ESRI president Jack Dangermond and described the work that the i.am.angel foundation is doing to help children in deprived areas learn and appreciate the value of GIS. His genuine desire to help give children the platform to build a better life from really shone through. He has a unique ability to spot potential and possibility, even comparing ghetto codes being used to protect gang territory to businesses writing code and protecting intellectual property. He is giving GIS the same attention he gave science and robotics with i.am.FIRST as currently being aired on entertainment television channel E! Whereas boxing brought his home neighbourhood of East Los Angeles a champion in Oscar de la Hoya, Will hopes that his STEM (science, technology, engineering and mathematics) campaign can see such a deprived area produce the next Facebook or Google.

Styling maps made easy

At Ordnance Survey we are committed to ensuring that our products are as easy to use as possible.

There is a growing need for our customers and partners to visually present our vector products in a suitable style, increasingly when it comes to serving mapping over the internet. For example, many companies serve Ordnance Survey maps via their Intranet service. Setting up these types of web-based services can be quite a time consuming process. Once all the geographic data has been loaded into a suitable database it can often take a while to apply the cartography – the visual portrayal of the data.

Understanding this, in December last year we released a set of Styled Layer Descriptors (SLDs) as one approach to help reduce the time and resource needed to properly apply cartographic styling. SLDs are commonly used in conjunction with a web server to style data for a web map service (WMS). Our SLDs have been developed in an open structured format and can also be converted to desktop GIS readable style sheets, enabling vector products to reflect the familiar Ordnance Survey look and feel.

Making sense of the data – styling Meridian 2 using our SLDs (raw data on the left vs. styled data on the right)

The SLDs can be downloaded free of charge under an open license which allows the modification of map features e.g. changing the colour of roads. They are available for all the products that we serve through our own WMS, OS OnDemand, including OS MasterMap Topography Layer and OS VectorMap Local.

Web Cartography for National Spatial Data Infrastructure’s Belgium, Leuven

Last month Paul attended a workshop on Web Cartography for National Spatial Data Infrastructure’s at the Faculty Club in Leuven, Belgium.

© Faculty Club 2013

Leuven is situated about 25 kilometres east of Brussels and is home to Anheuser-Busch In Bev, the world’s largest brewer group. The workshop saw a number of National Mapping Agencies (NMA’s) and other organisations get together to present on a number of topics around web cartography.

The workshop began with Sebastien Mustière from Institut Geographique National (IGN), France, giving the first presentation on the work done through their ‘Géoportail’, a web mapping service that publishes maps and aerial imagery ofFrance and its territories.

Sebastian spoke about the necessity for consistent styling and representation of features across all map scales focussing on the need to maintain user experience. He highlighted this by showing some work IGN have done to standardise map legends and to automatically derive up-to-date vector maps from vector geographic databases.

Map design: a list of helpful online resources

Whether they’ve been making maps for 20 years or two weeks, just like any designer, cartographers need inspiration when starting their latest project.  Inspiration can come from many places and take many forms.  Here at Ordnance Survey we use a range of resources and we want to share some of them with you.  In this post we list several online resources that can help with your latest map design; from choosing the right colour palette to selecting great fonts.  Some of these resources are specific to map-making and some are more general.  It is worth noting that they are not tools for making maps but tools to help with the map design process.

Although by no means a definitive list, these are some of the tools and resources that we refer to and use regularly and we have sorted them into four categories: colours, fonts, symbols and map inspiration:

 

Colours 

The use of colour is very often fundamental to the success of a map.  Colour can help with many elements of map design from improving visual contrast to simply catching the eye.   

ColorBrewer 2.0 is a great tool for selecting colour schemes that are specific to maps, especially helpful when mapping various classes of data.

Michael Palin: A Life in Maps

Michael Palin talking to BCS members

We recently attended a talk by Michael Palin at the Royal Geographical Society (with IBG) in London. Hosted by the British Cartographic Society (BCS), this talk was billed as the headline event in a year that marks the society’s 50th anniversary.

Upon our rain-drenched arrival, we took to our seats in the impressive Ondaatje Theatre and waited intently as BCS president, Peter Jones introduced the guest speaker to the stage.  As former president of the Royal Geographical Society, Michael Palin was in familiar surroundings. He began his hour-long talk by reciting memories of his childhood when he would spend long periods of time pensively poring over maps and atlases, overwhelmed by the sheer vastness of the world.  It was these graphical depictions of the world that ignited his desire to travel, something for which he is now notorious.  His love of maps was evident as he told of one atlas that he owns and treasures, a family heirloom which he has had refurbished. Of the maps that accompany him on his travels he said, “maps, like notebooks, are the raw materials of my work, constant companions.”
