What is ISO contour?
Iso contour draws demarcation lines in equal steps, according to number of divisions specified, between zero and the maxium value.
Unlike falsecolor, the resulting image will contain colored lines of equal value overlayed upon the true color luminance or illuminance image ..
What do you mean by contour line?
Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. map: contour lines. The diagram illustrates how contour lines show relief by joining points of equal elevation.
What does contours mean in geography?
Definition: Contours are a collection of lines found on maps that show mountains, valleys and landforms. Contours are measured from sea level.
What are the 5 Rules of contour lines?
Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff. Rule 4 – every 5th contour line is darker in color.
What’s a topography?
Topography is the study of the forms and features of land surfaces. The topography of an area could refer to the surface forms and features themselves, or a description (especially their depiction in maps).
What is ISO height?
The geopotential height is the distance above the Earth’s surface if it was a perfect and flat sphere. Isohypse are shown on a constant pressure surface. For example, when looking at a 850 mb chart, all isohypses no matter their value are located at 850 mb.
What are called ISO lines?
: a line on a map or chart along which there is a constant value (as of temperature or rainfall)
How do we use contour lines?
Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain constant. Contour lines show elevation and the shape of the terrain. They’re useful because they illustrate the shape of the land surface — its topography — on the map.
What are lines of equal depth called?
Isobath: lines of equal depth (generally below sea or lake level). Isobathytherm: lines of equal temperature at given ocean depths. Isocheim: lines on a map through places of equal mean winter temperature. Isochrone: lines on a map joining points that can be reached in equal time from a given origin.
What are lines of equal elevation called?
In cartography, a contour line (often just called a “contour”) joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
What is the rule of V’s?
The Rule of V’s: When a bed crosses a valley, the outcrop pattern of the bed will ‘V’ or curve in the direction that the bed is dipping in map view. Conversely, when a sedimentary bed crosses a ridge, it will ‘V’ in the direction opposite to its dip. … A horizontal bed will parallel topographic contours on a map.
What are 3 types of contour lines?
There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary.Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. … Intermediate lines are the thinner, more common, lines between the index lines.More items…
What is Isonif?
A line on a map connecting places of equal snow depth.
What are the three components of a map?
There are three Components of Maps – distance, direction and symbol.
