Inspired by the Mapbox blog – Tim Manners in our OS Labs team built this awesome demo application to showcase the dynamic hillshade. The demo includes a widget which enables you to change the light source directly on the client and see the map change in real-time. Tim used our OS Terrain 50 DTM grid dataset to generate a series of Terrain-RGB tiles. These tiles contain elevation data encoded in raster PNG tiles as colour values that can be decoded to raw heights in metres and rendered on the client-side for customisable terrain visualisations. Take a look below for how it appears when combined this with the OS Open Zoomstack Vector Tile API:

Following our OS OpenData formats trial, we’re continuing to work to improve access to our opendata offerings. Our team have developed OS Open Zoomstack which makes elements of our opendata available as one map in one file to be used for GIS, web, mobile or offline use.
You can try out OS Open Zoomstack over the next three months. All we ask is for your feedback to shape its development for potential wider release. We believe that this will improve access to OS data and help current and future users to use our data in new ways. The trial is also a fantastic opportunity to test how we approach the development of Open MasterMap recently announced by the Geospatial Commission. This is an important step on the Open MasterMap implementation project highlighting our commitment to working with developers and the geospatial community to improve accessibility and usability of OS data.
What is OS Open Zoomstack?
As part of the Prime Minister’s London Tech Week round-table event, earlier this week the Government announced that key parts of OS MasterMap will be made openly available for the public and businesses to use. The announcement is one of the first projects to be delivered by the Geospatial Commission in conjunction with us.
We are looking forward to supporting the Geospatial Commission in making this data more accessible and more widely used to continue our open data journey. In 2010 we launched OS Opendata and since then, we have continued to invest in new open data products and initiatives to enable innovation and growth in the digital economy. Over the past eight years we have seen our open data downloaded 1.9 million times. On average, 150 people download OS OpenData every day. That’s 54,750 people a year. Here is a quick trip through our open data journey highlighting some of the key milestones.
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.
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.
Calling all OS OpenData users!
Have you struggled to get to grips with GML? Have Shapefiles left you feeling positively un-shapely? Do you dream of a Dump file? Maybe you get giddy over a GeoPackage? Then you may want to take part in our OS OpenData trial that’s being announced at FOSS4G in London today…
It’s been six months since we released OS Open Greenspace, showing publicly accessible leisure and recreations spots in urban Britain, and it’s been fantastic seeing people using the map and finding new places to GetOutside. But did you know that it wasn’t the first greenspace map in Great Britain? Or that there are other important reasons to capture green spaces? Julie Procter, Chief Executive of Greenspace Scotland tells us more.
Why greenspaces matter
Greenspaces matter to people and make a big difference to quality of life, improving health and well-being, delivering environmental services, and creating places where people want to live and businesses choose to invest.
We know that greenspaces can provide cost-effective and sustainable solutions to some of the most urgent problems facing us today – our health, our communities and our economy. To deliver these wide-ranging benefits, and to safeguard the management of our open spaces, we need accurate information about the type, extent, distribution and accessibility of greenspace.
National Allotment Week kicked off yesterday, celebrating the hard work that volunteers, councils and organisations put in on all of the sites across the country. To mark the week, allotment groups are opening their gates and holding barbecues, plant and produce sales, allotment tours, competitions and exhibitions, coffee mornings and afternoon teas – many of them raising funds to support local charities.
Allotments are a fantastic way to #GetOutside and enjoy some fresh air, meet new people, and grow your own fruit and vegetables. The National Allotment Society say that 30 minutes of gardening on your allotment can burn around 150 calories, the same as doing low impact aerobics. Plus, allotments provide essential habitats for wildlife. Just 1 square metre of land can support hundreds of different species.
