sampleTerrainMostDetailed(terrainProvider, positions) → Promise.<Array.<Cartographic>>
Initiates a sampleTerrain() request at the maximum available tile level for a terrain dataset.
Name | Type | Description |
---|---|---|
terrainProvider |
TerrainProvider | The terrain provider from which to query heights. |
positions |
Array.<Cartographic> | The positions to update with terrain heights. |
Returns:
A promise that resolves to the provided list of positions when terrain the query has completed. This
promise will reject if the terrain provider's `availability` property is undefined.
Example:
// Query the terrain height of two Cartographic positions
var terrainProvider = Cesium.createWorldTerrain();
var positions = [
Cesium.Cartographic.fromDegrees(86.925145, 27.988257),
Cesium.Cartographic.fromDegrees(87.0, 28.0)
];
var promise = Cesium.sampleTerrainMostDetailed(terrainProvider, positions);
Cesium.when(promise, function(updatedPositions) {
// positions[0].height and positions[1].height have been updated.
// updatedPositions is just a reference to positions.
});
