OS Data Hub to canvas: bring your favourite GB locations to life

Software: ArcGIS Pro 2.5
Data: OS Open Zoomstack

There are currently a number of examples in the geospatial industry of people using various different styles to create interesting and artistic outputs. The brilliant John Nelson recently wrote a blog on paper terrain styles which inspired me to create my own map using OS OpenData that I could then print on to canvas.

This blog post will outline the steps I took to obtain and process the data to create the final output. I used Esri ArcGIS Pro for this project, but similar styles and tutorials exist for other GIS software.

Space, maps and the vulnerable – how integrated spatial data can help society

Throughout the coronavirus pandemic, we’ve been supporting the country’s response with our data. In April, we announced the release of an additional Covid-19 licence (extended until March 2021). This enables organisations, developers and individuals to use OS data, free at the point of use, for the specific purpose of supporting the UK response to Covid-19.

Since using our Covid-19 licence, we’ve welcomed 4 Earth Intelligence (4EI) as an OS partner! For this week’s OS Developer blog, their Chief Technology Officer Richard Flemmings explains how OS data is enabling their work to address climate change…

Air, surface and soil temperatures in cities are higher than their surrounding rural areas, predominantly due to the modification of land cover. The compact design of cities and the lack of vegetation and green spaces means that heat gets trapped within the urban area from both natural and waste heat energy. This is created from everyday life such as heat escaping from insulated buildings and is known as the urban heat island effect.

Satellite data analysis is complex and most people think it’s beyond their skill to understand and use it. However, that’s what we do and it’s 4EI’s core mission – we take complex science and distil it into information and insights that are valuable to our customers – at its simplest, this includes making maps.

Meet the team: Alina Piotrowska

Alina Piotrowska.Continuing our OS Developer content and adding to our series of blogs introducing the people that make up OS, our Associate Data Management Specialist Alina Piotrowska shares a day in the life of a data steward…

When did you start at OS?

I joined OS back in May 2019 as an Associate Data Management Specialist in the Data Management and Requirements team. A large part of my role is to care for our data and to make sure it is meeting customer requirements.

One of our data principles states that OS data ‘is cared for’. This means we treat our data as though it is our own; protecting and nurturing it. We recognise it as a valuable asset, look after it and ensure it gets the time, resources and prioritisation it needs. We do this to ensure that it delivers our outcomes.OS data principles.

Building Passport – the story so far

As a cohort member of the Geovation Accelerator Programme, founder and CEO of Building Passport Rupert Parker explains how he has used OS data to support his PropTech start-up…

Building Passport website screenshot.In recent years, there has been a lot of discussion around the suitability of today’s systems and methods for preventing and reducing incidents relating to fire in our built environment.

Three years have passed since the Grenfell Tower fire in 2017 and we are on the verge of legislative change to avoid similar events happening in the future. This will revolutionise the status quo of building ownership and operation.

I founded Building Passport Limited to facilitate this transformation, whilst basing the business on the ultimate vision of creating a safer built environment. Read More

PropTech start-up using OS data to re-imagine buying property online

As co-founder of property.xyz, Robert Jones has been investing in property for more than 15 years and creating data led content with Property Investments UK for over 8 years. As a member of Geovation, Robert explains how his company has been utilising OS data with the aim of building the world’s most intelligent property platform…

Carly Florina, ex-CEO of Hewlett Packard once said, “the goal is to turn data into information, and information into insight”, and she couldn’t be more right.

Because while collectively we are gathering data at a greater scale than ever before, the usefulness of it all remains largely elusive.

As such, lying before us, at the beginning of the data revolution, are vistas of untapped potential. Companies possessing a vision of how to transform the information at our disposal into something useful find themselves empowered to make a meaningful difference in their respective industries like never before.

As a portal made for property investors by property investors, our mission at property.xyz is to build the world’s most intelligent property platform. Read More

Bringing the OS Data Hub to desktop GIS

As the Technical Director at Cadcorp, Martin Daly has written this week’s #OSDeveloper guest blog to share his experience of the new OS Data Hub and desktop GIS…

At Cadcorp, we have, for the best part of 30 years, endeavoured to ensure that our Cadcorp SIS – Spatial Information System® suite of GIS software supports all of the wide variety of Ordnance Survey data products, in all of the wide variety of data supply formats, in as simple and effective a way as possible.

We’ve worked very hard over those years to allow end-users to, for example, drag-and drop file-based data in the format supplied by OS. That capability began all the way back with Land-Line NTF in the 1990s:

Addressing matters

Here at OS, we have an array of addressing products which can be utilised based on specific customer requirements. We have designed an interactive StoryMap that gives users an introduction to Code-Point, Code-Point with Polygons, Code-Point Open and AddressBase products.

This resource explains some key points regarding these addressing and location datasets. As well as answering some of our most asked questions, we have included two case studies (which focus on insurance and navigation) to highlight where certain datasets might be more appropriate to use.

In case you missed our big news, back in July we launched the OS Data Hub. As our new data platform, the OS Data Hub is transforming the way people access, share, and innovate with location data.

DataIQ connects, educates and supports people in data and analytics. The platform focuses on the needs of data and analytics professionals from global, FTSE 100, large and mid-market organisations.

As a result of our launch, Product Manager Charley Glynn and Developer Advocate John Hoopes were invited to be guests on the DataIQ podcast.

Creating your own vector tiles

As part of our developer series, we recently discussed the benefits of vector tiles in one of our previous blog posts.

OS Open Zoomstack and the OS Vector Tile API already offer some amazing mapping which can be used as the basis for overlaying other information. There are various ways to add data overlays to your base map including data received from Web Feature Services (WFS) such as the OS Features API or simply GeoJSON files which are stored on your web server.

Although both these options are perfect for smaller volumes of data (in terms of number of features and/or geometric complexity), sometimes it makes more sense to take advantage tiled vector data which can enable data of any size to be quickly rendered in your browser.

The OS Vector Tile API already offers a selection of data overlays but, with the right tooling and a bit of data processing, it is relatively straight-forward to generate your own.

In this blog, we are going to look at the steps involved in creating your own vector tile overlay using the parliamentary constituency polygons from the Boundary-Line dataset. Although we are using the parliamentary constituencies in this example, it is possible to swap in any of the administrative and electoral boundaries (or alternatively the entire dataset as demonstrated here).

Comparing the past to the present with the new OS Maps API layers

As a Map Curator at the National Library of Scotland, Chris Fleet oversees the historical maps website https://maps.nls.uk. In this week’s #OSDeveloper blog, Chris offers us insight into his experience of the new OS Data Hub in the form of a guest blog…

We were keen to get our hands on the new OS Data Hub maps API layers when these were launched on 1 July. For the last ten years, the NLS has been happily using OS OpenData as a modern map layer in our maps website viewers, but the new OS Maps API layers have a number of advantages over these. Read More
