3D 地形地图 - 三维地形 · 海拔查询 · 测距工具

The 3D topographic map, based on OSMdroid and various tile sources, provides an efficient map browsing and surveying experience. You can search for locations and pinpoint them with a single click, long-press on the map to add and name them to your favorites, and view or delete them on the favorites page. The tools page supports multi-point route distance measurement and closed polygon area measurement; a single click takes you to a dedicated survey map. The settings page allows you to switch between default layers and metric/imperial units, and the location button automatically centers at the current position.
