      Envelope extent = tinDef.GetExtent();
      SpatialReference sr = tinDef.GetSpatialReference();
    }

    using (terrain = terrainLayer.GetTerrain())
    {
      using var terrainDef = terrain.GetDefinition();
      Envelope extent = terrainDef.GetExtent();
      SpatialReference sr = terrainDef.GetSpatialReference();
    }

    using (lasDataset = lasDatasetLayer.GetLasDataset())
    {
      using var lasDatasetDef = lasDataset.GetDefinition();
