X Y Z Mapping of Cities by AccuCities

X Y Z Mapping is a 3D city mapping process where Z value is captured in 3D space. 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 using stereo photogrammetry.

3D City Modelling Technology

Aerial mapping using Stereo Photogrammetry

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 this fairly complicated process of X Y Z mapping 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).

3D Terrain Map from Aerial Photographs

When creating terrain we capture points along curbs of roads, along green spaces and footpaths as well as any significant change in terrain profile. This results in accurate and detailed 3D Terrain map which is further post-processed to make the CAD format solid and separated into layers.

Accurate 3D Buildings Modelling

Once the terrain is captured, we move onto 3D buildings capture. For Level 3 models all roof features are manually captured by highly skilled digital craftsmen, resulting in 3D buildings models with consistent accuracy and correct geometry. Our buildings extent terrain by around 0.5 meter which ensures that models are watertight for applications such as 3D printing.

3D data in layers

Easy to work with

3D models are separated into layers such as Buildings, Roads, Greenspaces, Bridges, Embankment Walls and Trees layer.

X Y Z Mapping is a 3D city mapping process where Z value is captured in 3D space. 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 using stereo photogrammetry.

What is the difference between 3D city models?2022-03-28T21:11:02+01:00

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.

What 3D formats can I choose from?2022-03-28T21:07:55+01:00

Any model can be delivered as AutoCad solid .DWG, SketchUp .SKP or .FBX files.
