OptionalfeatureDeprecated with 1.8, use featureExpressionInfo instead. Ignores geometry z-values.
OptionalfeatureSets the offset distance, type and other parameters.
OptionalmodeDetermines how the service elevation values are combined with the basemap elevation.
OptionaloffsetOffset is always added to the result of the above logic except for
"onTheGround" where offset is ignored.
OptionalunitA string value indicating the unit for the values in elevationInfo. Applies to both offset and featureExpressionInfo. Defaults to meter if not set. Supported units: "foot", "kilometer", "meter", "mile", "us-foot", "yard".
