abstract fun wasCreatedByUpsampling(): Boolean

Gets a value indicating whether or not this terrain data was created by upsampling lower resolution terrain data. If this value is false, the data was obtained from some other source, such as by downloading it from a remote server. This method should return true for instances returned from a call to TerrainData.upsample.
