Toposcope
（重定向自Topograph）
A toposcope, topograph or orientation table is a marker erected on hills or high places which indicates the direction, and usually the distance, to notable landscape features which can be seen from that point. They are often placed in public parks, country parks, the grounds of stately homes, at popular vantage points (especially accompanying or built into triangulation stations) or places of historical note, such as battlefields.
