Elevation contours and points (WMS)

The service includes altitude data on land and depth data in the territorial sea: 1) the same height lines at 2.5 m intervals, 1 m of the same height line; 2) isobath lines at 5 m intervals, 2 m isobath; 3) characteristic height and depth points. The data on the same altitude lines and elevation points have been produced from the height data of the Estonian topography database aerolasers scanning (LiDAR). Data on the same depth lines and depth points were generated by the Land Board from the data collection of the depth points of the Hydrographic Information System (HIS).本服务涵盖陆地高程数据与领海深度数据，具体包含以下三类： 1) 间隔2.5米的等高线（same height lines），以及间隔1米的等高线； 2) 间隔5米的等深线（isobath lines），以及2米等深线； 3) 特征高程点与特征深度点。 前述等高线及高程点数据，均基于爱沙尼亚地形数据库机载激光雷达（LiDAR）扫描获取的高程数据生成。 等深线及深度点数据，则由爱沙尼亚土地局依据水文信息系统（Hydrographic Information System, HIS）的深度点采集数据生成。
