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

How can I create automated data downloads?

Data can be incredibly useful. By analysing or interpreting the information contained in data, better decisions can be made.

Ordnance Survey is one of the world’s oldest data organisations. We have gathered information about Great Britain since 1791, organising, analysing and disseminating maps and other information. As information technologies have evolved from tables and charts and pen-and-paper calculations to databases, vector graphics and sophisticated machine learning algorithms, OS has been a leader in adopting and innovating new ways to capture, store, process and share valuable location information.

The challenge – managing data

Ordnance Survey’s cartographic house styles

Ordnance Survey has a rich cartographic history – we have been mapping the Great British landscape for 229 years! From navigating the countryside on foot to helping utility companies manage and track their assets underfoot, our maps offer a range of functions. As a result, our cartographers make lots of intricate design decisions to ensure that our maps meet the needs of each of our different users.

Our paper maps (and their digital raster data equivalents) carry their own beautiful cartography which is well established and well understood. A great example of this is our OS Explorer Maps. For many, these maps have a sentimental or nostalgic value – they can evoke memories of adventure and can connect the map reader to locations. Cartography is a powerful form of visual communication.

The benefits of vector tiles

Fast, customisable, versatile web maps

Web mapping has come a long way since the first map server was built in 1993 at the famed Xerox Palo Alto Research Center. Since then, users have come to expect intuitive, beautiful and instant maps on their desktop and mobile devices.

Why tiles?

The typical modern map user accesses map data on devices that usually don’t have the storage capacity for high resolution maps of the entire world. Instead, apps and websites show mapping data that is served as needed over the web.

When a web map is loaded, it is set to a zoom level and extent, which defines the level of detail and the area that will be visible in the viewer. A map server sends grid sections of the map, called “tiles”, to the user, where they are arranged in the right configuration to appear as a map. As the user pans and zoom in and out, requests for the correct tiles are sent, and the response is used to update the screen. Read More

All about OS MasterMap Topography Layer

Update: 1 July 2020, OS APIs now live and available via our OS Data Hub, sign up here

As Great Britain’s national mapping agency, we are responsible for keeping accurate, up-to-date location data and maps of GB for use by the private, public and third sectors.

We map GB’s topography, also known as “the arrangement of the natural and artificial physical features of an area” (Oxford). Every day a team of surveyors, pilots and analysts explore the country to discover changes to the topography and in doing so, take measurements and record these changes in our database.

After much processing and organising, we make this available as the most detailed, current and comprehensive geographic dataset of GB: OS MasterMap Topography Layer. Read More

Which geospatial API do I need?

Topo mapWe recently introduced our new range of Mapping and Data APIs which are available from the OS Data Hub.

In this week’s post, we want to help you choose the right one for your use case by presenting a series of user stories and recommending the API that is the best fit. In some instances, there will be more than one option and your choice may come down to experience, software interoperability, or preference.

Told from the perspective of the individual, a user story is a short description of a feature stating the requirement and the reason behind it. Interested? Read on to find out our use case advice. Read More

A different perspective on the Highlands with OS OpenData 

Guest blog by Alasdair Rae, University of Sheffield 

Thanks to the new Ordnance Survey Data Hub, it’s easier than ever for users to get their hands on the treasure trove of geographic data covering the length and breadth of Britain. In this article, I’ll explain how I used some of Ordnance Survey’s digital terrain model data to create a new map of the Scottish Highlands. I will also say a bit about the software and methods, and I’ve shared the data below so anyone who is interested can try it for themselves. But before that, let’s take a look back at the first ‘3D map’ of the Highlands.
