Remote sensing is a general term for geodata collection at a distance from the subject area.
Topography What is topography? Topography describes the physical features of an area of land. These features typically include natural formations such as mountainsrivers, lakes, and valleys.
Manmade features such as roads, dams, and cities may also be included. Topography often records the various elevations of an area using a topographical map.
Topographical Features Topography studies the elevation and location of landforms. Landforms - Landforms studied in topography can include anything that physically impacts the area.
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 topography. It is usually recorded in reference to sea level the surface of the ocean. The equator is a horizontal line drawn around the middle of the Earth that is the same distance from the North Pole and the South Pole.
The equator has a latitude of 0 degrees. Longitude is generally measured in degrees from the Prime Meridian. Topographical Map A topographical map is one that shows the physical features of the land. Besides just showing landforms such as mountains and rivers, the map also shows the elevation changes of the land.
Elevation is shown using contour lines. When a contour line is drawn on a map it represents a given elevation. Every point on the map touching the line should be the same elevation.
On some maps, numbers on the lines will let you know what the elevation is for that line. Contour lines next to each other will represent different elevations.
The closer the contour lines are to each other, the steeper the slope of the land. The lower map shows the contour lines for the above hills Ways Topography is Studied There are a number of ways that information is gathered to make topographical maps. They can be divided into two primary methods: Direct survey - A direct survey is when a person on the ground uses surveying equipment, such as levels and clinometers, to directly measure the location and elevation of the land.
You have probably seen a surveyor along the road sometime making measurements by looking through a leveling instrument sitting on a tall tripod.
Indirect survey - Remote areas may be mapped using indirect methods. These methods include satellite pictures, images taken from planes, radar, and sonar underwater. Worker performing a survey What is topography used for? Topography has a number of uses including: Agriculture - Topography is often used in agriculture to determine how soil can be conserved and how water will flow over the land.Topography is the study of the shape and features of the surface of the Earth and other observable astronomical objects including planets, moons, and asteroids.
The topography of an area could refer to the surface shapes and features themselves, or a description (especially their depiction in maps). A map that shows elevation surface Also shows features (topography) of the earth.
Natural features like rivers, lakes, mountains. Man . A topographic map shows how the ground is shaped and provides a way to calculate the height of the features on the map. This lesson explains what a topographic map is and how to determine the.

Pixel. a tiny dot that makes up computer maps. on a topographic map a heavier contour line that is labeled with elevation of that contour line in round units. This image shows the topography, or shape, of the Earth's surface, on land and below the oceans. Mountain ranges, subduction trenches, tectonic plates, and mid-ocean ridges are all visible in the image.
There are many kinds of maps and globes, but all give information on the world we live in. One type of map is the topographic map.
