4 amazing OS open data products you can use right now


On April 1, 2010, Great Britain’s national mapping agency, Ordnance Survey (OS), started to make some of its mapping data and geographic information freely available to the public, without any restrictions on re-use.

Today, OS OpenData consists of 14 continuously maintained products, including Royal Mail’s postcode data, administrative boundaries, greenspaces, and detailed basemaps. Countless cartographers and mapmakers have benefitted from these invaluable resources over the last decade. And listed below are our top open data picks that we believe can help you the most:

OS Boundary-Line

From Parliamentary constituencies to council wards, Boundary-Line maps every administrative boundary in detail. You can use the easy-to-read shaded maps to show the differences between regions or councils and bring the statistics in your reports to life.

While this data product is updated twice a year, OS also allows you to download historical county boundaries data from the late 19th Century – ideal for historians who need to analyze old census records and archives.

OS Open Zoomstack
