A spot height on a map refers to the elevation or height of a particular point on the map above a specified level, usually sea level. It is represented on the map by a dot or spot with a number indicating the height in meters or feet. For example, a spot height of 360m indicates that the point on the map is 360 meters above sea level. Spot heights are important features on maps because they help users to understand the topography and relief of the land, and to plan routes for hiking, climbing, or other outdoor activities.
