Anyone know the word which describes an outline drawing of buildings, hills & mountains etc which can be seen from a viewpoint, and labels the sights (sites?!) for the benefit of the viewer
I'm not sure that there's any one specific word of phrase, but the word orientation usually comes into it - eg orientation map or orientation diagram. Where the diagram is set out on a freestanding, round table, this is usually referred to as an "orientation table".
Famous, I think the term you are looking for in architecture is "elevation" which I have always taken it to mean a drawing of a proposed building in relation to its surroundings. In the elevations that were presented to me, the surroundings were sometimes labeled and sometimes not.
