Export buildings and terrain as a glTF model.

Live demoView code

What it does

Select an area of interest to export as a 3D model. This allows you to download the geometry of buildings and terrain. The generated glTF model can then be imported into most popular 3D modeling tools for further use.

Under the hood

Sketch tool

Interactively select the area to download using the Sketch tool. Tooltip inputs allow specifying the exact coordinates of the model origin.

Query mesh geometries

Access the 3D geometry of buildings and terrain directly in the client. Different APIs help you perform the queries to the respective elevation- and 3D object layers.

Manipulate mesh geometries

The Mesh utilities API allows you to merge buildings and terrain to a single 3D model. In addition it can convert the georeferenced 3D data to a cartesian coordinate system directly in the browser.

Convert to glTF

Finally the Mesh API allows exporting the 3D geometry to a binary glTF representation, which can than be imported in your 3D modeling software of choice for further use.
