Ordnance Survey free data for a home
What OS's three free APIs add for one home: OS Linked Identifiers (its street and building references), OS Names (the places around it) and the OS Features OpenData layers (roads, railways, pylons, water, woodland and sites around it). The home is the OS address point nearest the postcode's centre unless a UPRN is given.
The home
- UPRN 200002936771 · 1 m from the postcode centre
- British National Grid 300954, 195274 · 51.647512, -3.432926
Its street and building (OS Linked Identifiers)
- Official street (USRN): 47402371 · Designated Street Name · 21 m from the home
- OS building or plot outline (TOID): osgb1000023712139
- Road link (TOID): osgb5000005186093026
- OS's links as at 2016-02-10
Use in the report: the home's street by OS's own reference, not by matching HM Land Registry's address text; the roof and plot checks on the outline OS links to the address, not the nearest one.

The building (OS NGD Buildings, premium)
Not available: the key cannot reach OS NGD API – Features. It needs a key from a project inside the OS Data Hub organisation on the Premium plan (the £1,000 a month credit), set as os_data_api_key. Then this panel shows the home's building with every attribute OS holds: floors, basement, roof shape and aspect, roof material, solar panels, green roof, age, construction material, height and use.
Premium data: £0.19 a request inside the Premium plan's free £1,000 a month; OS's terms allow showing it and caching it for 24 hours (kept here 24 hours), not storing it in a saved report without OS's written permission. Contains OS data © Crown copyright and database right.

OS vector map: colour schemes and OS's own boundaries
OS's National Geographic Database as vector tiles: every layer can be recoloured. OS's own styles and three of ours on the same data, and OS's boundaries as outlines.

Map: OS styles and layers to choose from
OS Maps API tiles (zoom 7 to 20) through the server, so no key reaches the browser; boundaries from ONS; the building, plot, garden and postcode outline from OS NGD. OS's vector boundary tiles (OS Vector Tile API) need that API added to a key's project.
The lie of the land (Natural Resources Wales LiDAR ground)
- The plot's slope: 21.7% (6.5 m across the 15 m round the home), downhill to the east
- A hollow or a rise? The home's ground is 209.1 m above sea level; at 25 m round it the ground averages 209.33 m (50% of it lower than the home); at 50 m round it the ground averages 209.44 m (50% of it lower than the home); at 100 m round it the ground averages 212 m (50% of it lower than the home); the home sits in a hollow.
- The lowest ground within 50 m: 14.85 m below the home, 50 m away
- Where rain runs: from the home it heads north-east, 139 m, falling 15.66 m, and gathers in a low spot (drawn in blue in the 3D view).
Bare earth: walls, kerbs and drains are not in it, so this is the shape of the land, not a flood model. Environment Agency LIDAR Composite DTM and first- and last-return DSM, 1 m (England): © Environment Agency copyright and/or database right, Open Government Licence v3.0.
The view from upstairs (worked out from the LiDAR)
- From a window 4.3 m up (213.2 m above sea level), over roofs and trees, to 500 m:
- A park or green space: in sight, nearest 18 m to the east
- Water: not in sight
- The railway: not in sight
- A main road: not in sight
- A tall building (15 m or more): in sight, nearest 142 m to the east
- The longest view: 296 m to the east
Hover over the rose or a line above to see where it is; click to look that way from the window in the 3D view below. Our own sight lines every 3° across the EA's first-return surface on a 4 m grid, matched to OS Open Zoomstack (parks, water, railway, main roads) and the LiDAR (tall buildings). A window's real outlook depends on which side it is on and on what grows.

The home in 3D on LiDAR: OS buildings on Natural Resources Wales's ground and roofs
The ground is Natural Resources Wales's 1 m LiDAR terrain; each OS building outline is walled to its eaves and roofed with the LiDAR surface inside it (real ridges and dormers). Above the ground outside OS's outlines, the LiDAR's last return tells trees (green: the laser got through) from solid things: grey where a building's roof runs past OS's outline, brown where OS has no building at all. Roofs OS records as having solar panels carry dark panels, and green roofs are green. The home is orange. Drag to turn, shift-drag to move, scroll to zoom, click anything for what it is.
Flooding follows FloodRadar's 3D prototype in our own code: pick one of Natural Resources Wales's flood maps to drape it on the ground, and raise the river with the slider. Water spreads only from a river or lake in the box, over ground, floors and defence crests lower than it; buildings turn orange when water reaches their walls and red when it is likely inside (floors assumed 15 cm above the ground). The marks on the slider are the Environment Agency's depth bands at the home and the nearest gauge's record.
