Is contour interval and vertical interval equal?

Not necessarily but yes, it can be. A contour interval is the difference in elevation between successive contours, while a vertical interval is the distance between any two contours. So yeah, it can be the same sometimes.


The contour interval is a measurement of?

the distance between mean sea level and any given contour line


How can contour lines demonstrate the levels of elevation on a map?

Each contour line represents a certain elevation, and the difference in elevation between any two adjacent countour lines is constant. So, for example, if in the map area there were a cone-shaped feature, like a volcano, the shape would be shown as a circle in a circle in a circle in a circle (and so on). The more contour lines you cross along a path, the steeper the climb, and the fewer contour lines you cross on the path, the more level it is.


What are the characteristics of contour?

One of the characteristics of contour is that the variation of the vertical distance between any of the two contour lines are usually assumed to be uniform. The other characteristic is that all the points on a contour line are of the same elevation.


What does the spacing of contour lines tell us?

Contour lines refer to the elevation of a line as it runs through a mapped area. For instance a 1,000ft. contour line might meander through an open field or wrap completely around a hill. On any map the "Contour Interval" is indicated somewhere as 25FT or 50ft. or 100ft. meaning that it will be this distance vertically between lines of the same altitude. In flat lands it may be a long distance between contour lines but on a steep slope they might be crowded close together.


Why is there a difference between NZ contour lines and Australian contour lines?

Maps can be created with differing scales. These days, it's childishly simple for the cartographer to change any scale on any parameter before printing. It's possible one of your maps is 10 meters/interval while the other is 5 Or, if one of your maps was printed before SI was made standard, it might be 'Imperial' Or, if one of your maps was published in US First things to check on any map; Date, scale, orientation, contour interval


Why contour line never cross?

Contour line's measure elevation, there cannot be a space with two different elevations at the same time. For example, a hill can be 1,000 feet tall at the summit but not also 5 ft at its summit (unless you're in some parallel dimension). So no, they never cross.


What does a plain look like on a map?

On a map that uses contour lines to represent height, a flat plain should show very few (if any) contour lines.


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.


Difference between tangent and parallel lines?

parallel lines never touch, never get any closer or any further apart. tangent lines touch at one point


What is the difference between perpindicular and intersecting lines?

Intersecting lines can cross at any angle. Perpendicular lines cross or meet at 90 degrees only.


Which area of this map has the steepest slope?

To determine which area of the map has the steepest slope, look for regions where the contour lines are closest together. Steeper slopes are indicated by these closely spaced contour lines, while flatter areas have lines that are further apart. Additionally, consider any elevation changes in relation to the distance between contours to identify the steepest section accurately.
