Coelho also emphasizes a universal language in The Alchemist, one that all creation speaks. The Earth is alive and has a soul, and all parts of the Earth, from the wind to the sun to the sea to us, are all interconnected as one.
Topographic maps are also commonly called contour maps or topo maps.. In the United States, where the primary national series is organized by a strict 7.5Â° grid, they are often called topo quads (or quadrangles).Topographic maps conventionally show topography, or land contours, by means of contour lines.Contour lines are curves that connect contiguous points of the same altitude (isohypse). In other words, every point on the marked line of 100 m elevation is 100 m above mean sea level.opographic maps conventionally show topography, or land contours, by means of contour lines.

Much like any other type of survey, a topographic survey, or topo survey for short, is done to locate natural and man-made features on a particular parcel of land. This is sometimes called planimetric features or things you can see from a plan view as if you were hovering over the site. breakline is a point at which the contour changes abruptly, like the back of a curb, or the center line of a roadway. An aerial topo survey is done from aerial photos taken from an airplane or helicopter at a certain distance above the ground.
