Geolocation extension

API Reference:

Provides functions for converting GPS coordinates in WGS-84 format { x: Longitude, y: Latitude, z: Height(m) } into
Viewer scene coordinates and back. Supports a single 3D model loaded into the scene.

The extension id is: Autodesk.Geolocation





Does the model contain geolocation data?

returns boolean  (true when the model contains geolocation data)



Converts viewer coordinates (obtained with something like viewer.clientToWorld()) into { x: Longitude, y: Latitude, z: Height (meters) } in WGS-84 format.
returns {THREE.Vector3}:  (GPS coordinate in WGS-84 format: { x: Longitude, y: Latitude, z: Height } )

lmvToLonLat( lmvPoint ) 


Converts coordinates from { x: Longitude, y: Latitude, z: Height (meters) } in WGS-84 format into viewer scene coordinates.
returns {THREE.Vector3}:  (3D point in the scene)

lonLatToLmv( lonLat )



Returns a Google Maps URL with a PIN on the specified GPS location. When no argument is provided, the URL will use the Model's geolocation if available.

openGoogleMaps( [ pointLL84 ] )


Click the model to set points and see optional panel UI for testing and debugging
