The topography is the study of the shape and features of land surfaces. The topography of an area could refer to the surface shapes and features themselves, or a description (especially their depiction in maps).
What Is Topography?
The topography is a broad term used to describe the detailed study of the earth’s surface. This includes changes in the surface such as mountains and valleys as well as features such as rivers and roads. It can also include the surface of other planets, the moon, asteroids, and meteors. The topography is closely linked to the practice of surveying, which is the practice of determining and recording the position of points in relation to one another.
Modern-day topography is generally concerned with the measurement and recording of elevation contours, producing a three-dimensional representation of the earth’s surface. A series of points are chosen and measured in terms of their horizontal coordinates, such as latitude and longitude, and their vertical position, in terms of altitude. When recorded in a series, these points produce contour lines which show gradual changes in the terrain.
While most people think of land surveys in the most basic sense—that is, the drawing of the boundaries of property—there are actually many different ways of surveying that service many different industries.
Surveying has to do with the determination of the relative spatial location of points on or near the surface of the earth.
Topographic maps offer detailed information on a particular area and are used for several types of activities such as emergency preparedness, urban planning, resource development, and surveying to camping, canoeing, adventure racing, hunting, and fishing.
Topographic maps of the seafloor. Detailed depth contours provide the size, shape, and distribution of underwater features. The map serves as a tool for performing scientific, engineering, marine geophysical and environmental studies, that are required in the development of energy and marine resources.
The variation in relief constitutes the morphology of the ocean floor. Charting of the ocean is very important for many reasons: it affects circulation, a potential site for living and non-living resources, submarine navigation, geophysical exploration, etc.
A topographic map is printed on a flat piece of paper yet it provides a picture of the terrain and manmade features through the use of contour lines, colors, and symbols. Contour lines represent the shape and elevation of the land, such as ridges, valleys, and hills.
What are examples of topography?
Examples include mountains, hills, valleys, lakes, oceans, rivers, cities, dams, and roads. Elevation – The elevation, or height, of mountains and other objects, is recorded as part of the topography. It is usually recorded in reference to sea level (the surface of the ocean).
The topography is a detailed map of the surface features of the land. It includes the mountains, hills, creeks, and other bumps and lumps on a particular hunk of earth. This handy word is a Greek-rooted combo of topos meaning “place” and graphein “to write.” It’s the geographical contours of the land.
An objective of topography is to determine the position of any feature or more generally any point in terms of both a horizontal coordinate system such as latitude, longitude, and altitude. Identifying (naming) features, and recognizing typical landform patterns are also part of the field.
