elevationSamplerElevationSamplerreadonly

An elevation sampler that may be used to sample and query elevation values from the ground surface that is currently being displayed.

The elevation sampler is not supported for MapView and may be null while the ground surface display is being initialized.

The resolution of the sampled values depends on the ground elevation display resolution (high resolution close to the camera, low resolution far away from the camera). Because of the dynamic nature of the display resolution, the demResolution property of the returned sampler will always return `{ min: -1, max: -1 }.

If higher or more consistent sample resolution is required, then consider creating a sampler at the desired resolution using ElevationLayer.createSampler or Ground.createSampler.

Example:

var elevationSampler = view.groundView.elevationSampler;
// watch for changes in the elevationSampler
elevationSampler.on('changed', function() {
  // get z-values from the elevation displayed in the view
  var zEnrichedGeometry = elevationSampler.queryElevation(geometry);
});
