A line of equal elevation, commonly known as a contour line, is a line on a map that connects points of the same altitude above a reference level, such as sea level. These lines help to represent the three-dimensional shape of the terrain on a two-dimensional surface, indicating hills, valleys, and slopes. Contour lines that are close together suggest steep terrain, while those that are spaced farther apart indicate gentler slopes.

Which type of objectives have angle of elevation?
The angle of elevation is looking at an object above your line of sight.
What does a contour line indicate when it points downhill?
When a V-shaped contour line points downhill, it means that the contour line is under very low elevation. And incase your wondering about when the contour line is uphill, it means that the elevation level is very high.
What is the relationship between the angle of elevation and the angle of depression between two points?
The angle of elevation is the angle formed between a horizontal line and a line of sight upward to an object, while the angle of depression is the angle formed between a horizontal line and a line of sight downward to an object. When two observers are at different heights, the angle of elevation from one observer to the other is equal to the angle of depression from the second observer to the first. This relationship holds true in a right triangle formed by the line of sight and the horizontal lines, demonstrating that these angles are complementary. Thus, if one angle increases, the other decreases correspondingly when measured from a common horizontal plane.
What do use a broken line for when drawing an elevation?

What are conour lines?
Contour lines are used when you have spatial data, with the x,y values identifying a particular point and z is the value at that point. It could be elevation above sea level, temperature, pressure or any other measurable property. Contour lines identify where the data suggests equal values should exist. On an elevation map, contour lines show the elevation of equal values points. A 50 ft contour line would go through all points where the data suggest should be at 50 ft elevation. See related links.
What is a line connecting points of equal elevation?

Line drawn on a topographic map to join points of equal elevation?
lines of equal elevation are called contour lines.
What is the difference between contour lines and relief?
Contour line connect points of equal elevation on a map, whereas relief is the difference in elevation from the highest and lowest on a map.
What is a contour on a topographic map?
A contour is a line that joins points of equal elevation.
What line on a map connects the points of equal elevation?
Contour lines or also known as isohypses, connect points of equal elevation on a map. Contour lines can be curved, straight or a mixture of both. The lines on a map describe the intersection of a real or hypothetical surface with one or more horizontal planes.
How can one determine elevation using a topographic map?
To determine elevation using a topographic map, look for contour lines that connect points of equal elevation. Find the contour line closest to your location and determine the elevation value listed on that line. Elevation can be calculated by adding or subtracting the contour interval value from the listed elevation.
Do Equal points of elevation on a topographic map are connected by contour lines?
A contour lines connects points of equal elevation.
What is a Contour line on a topographic map?
A contour line on a topographic map represents a specific elevation above sea level. It connects points of equal elevation and helps to show the shape of the land, such as hills, valleys, and slopes. The spacing between contour lines indicates the steepness of the terrain.
What is the difference between and index contour and a regular contour line?
An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.
What does a contour line measure?
The scale of contour lines on a topographic (terrain) map is called the "contour interval".
How is an isobar like a contour line?
Both isobars as contour lines connect points on a map along which values of a given parameter are equal. Contour lines connect points of equal elevation while isobars connect points of equal pressure.
What is the name of the line on a map that joins places of equal height?
The name of the line on a map that joins places of equals height is "the contour." Contour lines are lines of equal elevation, whereas isohypse are lines of equal geopotential height.
