X Y Z Mapping of Cities by AccuCities
Our production team is highly skilled and take great pride in capturing highest quality 3D city models. Every point and every line in our 3D city models is manually captured captured using stereo photogrammetry. We call this process X Y Z Mapping.
Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points. We use stereo photogrammetry using latest high-resolution aerial imagery to capture our 3D Models. To explain complicated process in very few words, as survey plane flies over a city area, it takes series of photographs which overlap by 60%. With each photograph its GPS position, height, tilt, pitch and roll are recorded. Using this data + camera calibration data (to eliminate lens distortion effects), the imagery is triangulated to its correct real-world coordinates.
Once the source aerial imagery is triangulated we can finally start with the capture process. In areas where two images overlap, we project one image into one eye, the second image into another eye and and this way we are able to see the Z value (depth).

25 km sq Base 3D Model of London
Manually captured from 2016 imagery, this 3D Model covers 25 km2. Light, Detailed & Accurate to 200 cm, the model is easy to work with and fantastic value at less than £200 / km sq. Delivered as .DWG, .SKP or .FBX files.
High Detail 3D London Subscription
Subscribers can chose 3D Model covering either 25 km2 or 40 km2 of central London. Accurate to 15cm, dataset is always updated from latest aerial imagery. Company-wide licence from £1,000 + VAT / month.
Latest Source Aerial Imagery
The High Detail 3D Model is manually captured using stereo photogrammetry. The source photography and its associated data is from the latest high-res 12.5cm GSD imagery collected in September 2016. This gives the user the confidence that the most recent additions to the London skyline are included in the 3D model.
Accurately Captured Buildings
Level 3 Model buildings are accurate to 15cm in all axis. Using aerial stereo photogrammetry, all roofs features and structures are precisely manually captured with correct shapes and slopes. Vertical walls of buildings in our Level 3 3D models are made as downwards extensions of roof structures. If facade detail is required, customers can purchase Level 4 models with 20% discount.
Accurately Captured Terrain
The terrain in the Level 3 3D Model of London is not flat. It is manually captured using the same manual photogrammetry method as buildings and is accurate to 20cm in all axis at curb level.
Terrain is separated into land use categories such as roads, man-made surfaces, greenspaces and water body.
3D data structured in Layers
3D Models of London in Level 3 are structured in Layers. Level 3 Buildings are on one layer, terrain model is separated in layers such as Roads, Man-made surfaces, Greenspaces and Water body, but also Bridges, Embankment Walls and River Structures. Last layer in this dataset is the Trees layer.
Future Skyline Layer Included with London Models
Future Skyline Layer is a product available to our Wide Area 3D Model of London subscribers. We collect information from planning portals and turn submitted drawings into a massing 3D Model which best represents planned development. Now also included with qualifying Level 3 Tiles orders.
Future Skyline Layer is available for Nine Elms / Battersea, Southbank, Blackfriers, City of London and Canary Wharf.
Variety of File formats
Level 3 3D models are delivered in AutoCad Solid DWG, SketchUp SKP and Filmbox FBX formats for easy editing that suits most workflows. The 3D Model is easy to import into Revit, 3D Studio Max, Maya or Cinema 4D.
Company-wide Multi-use Licence
We put as few restrictions on how you can use our 3D models as possible. Our End User Licence Agreement is easy to understand and allows anybody in your company to use the data over and over again for 5 full years.
Frequently Asked Questions:
You don’t need to have an account with us to order 3D models.
Level 3 models can be ordered from as little as 0.1 km2 (which is about 330 x 330 meters in real world).
Level 2 models can be ordered from as little as 0.25 km2 (which is about 500 x 500 meters in real world).
Custom 3D models can be ordered in any shape – simply draw a map mark-up , send it over to us and we will come back to you with a quote.
We prefer map mark-ups for quotes to be sent via our Quoting Tool. If you are having any difficulties or have a map in any other format, simply email it to email@example.com with your name, company, required Level of Detail and your contact details and we will come back to you.
Business customers will be invoiced with 14 days payment term in or shortly after 3D model delivery. Non-business customers might be asked to pay via Card, PayPal or UK money transfer before we accept an order.
We will usually come back to you within 2 hours with costs and delivery times for your project. Once these are confirmed by you we will order imagery, set-up a Photogrammetry project, manually capture your 3D model, post process the data and deliver the 3D model to you in required format via a download link.
3D models are distributed under company-wide, multiple-use licence which covers the use of the 3D model for 5 years. We grant to the User a worldwide, non-exclusive licence to use the 3D Model to unlimited number of Derived products (renders, animations), Incorporated products (Interactive Application, import into custom software), conduct In-house work and use 3D Model data for Physicalization such as 3D printing.
Customers cannot distribute, alter to distribute or re-engineer the 3D model in any way. Read full EULA here.
Both Level 2 and Level 3 3D Models are manually captured from latest aerial imagery available for the area of interest.
Level 2 3D Models are accurate to 50 cm in all axis. The 3D Model is very light and low poly. Buildings are captured with correct roof shapes of main structures with only chimneys, parapet walls and dormer windows omitted. Terrain is accurate to 20 cm and separated into land use categories. Trees locations (captured with correct height and canopy width) are also included.
Level 3 3D Models are accurate to 15 cm in all axis. Buildings are captured with correct roof shapes and all features such as chimneys, parapet walls or dormer windows. Terrain is separated into land use categories. Trees locations (captured with correct height and canopy width) are also included.
Any model can be delivered as AutoCad solid .DWG, SketchUp .SKP or .FBX files.
Our High Detail 3D Model of London subscribers also receive Unreal Engine 4 app and all associated UE4 files.
Of course – feel free to Download AccuCities sample tile TQ3280SE. This large 500 x 500 meters sample can be used to evaluate our 3D models. The sample can be downloaded as AutoCad solid .DWG, SketchUp .SKP, FBX and .UE4 Project files as well as Interactive 3D Model. Different Levels of Detail 3D models are available in every format.
