Contour lines represent the shape and elevation of the land, such as ridges, valleys, and hills. The scale of Survey maps is given in the form of a ratio or fraction, without dimensions; the numerator is the distance on the map, and the denominator is the corresponding distance on the ground. As with field notes, remote sensing data (aerial and satellite photography, for example), is raw and uninterpreted. For example, if you are building a log cabin on a mountain that doesn’t have any established roads, a topographic map can help you plan a route through the forest. They can help to establish conservation areas such as watersheds and wind blocks. The topography was gently rolling, with thick peat extending in the lower parts and white sandy soils dominating in the upper parts.
