OS Open Zoomstack is now available as a fully supported open data product. Thanks to the 1200 people who took part in our trial and gave us feedback and helped bring this product to life.
What is OS Open Zoomstack?
A comprehensive vector basemap of Great Britain, it’s fast and easy to use and takes you from national to local in one scroll of the mouse or pinch of the screen. It’s highly customisable and can be used in apps, on websites and even offline. Available as one file (in two different formats) our latest open data offering comes with styles, a simple data schema and guides to get you started.
We’ve had such a great response to the trial and received a huge amount of feedback from the users, that we’re going to invest in making OS Open Zoomstack a supported product.
For both the downloads and the API we’ll be developing Alpha versions and continue to make changes based on your feedback. We’ll be doing an alpha release shortly for the various downloads. We’ll also continue supporting the API, and will update this with the new data from the Alpha while we plan the release of a fully supported version in the future. Please note that this may involve changes in the API URL at a minimum.
At this point we would like to say a huge thank you to everyone who has helped us to make this exciting step!
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:
