The angle of elevation is looking at an object above your line of sight.
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.

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.
Slope is expressed as the percentage of rise/fall in elevation over a specific distance and is determined by dividing the change in elevation by the length of the line. So if a line segment is 10 feet long and rises or falls 1 foot in elevation, the slope would be 1 ft/10 ft or 10 percent.
property line
lines of equal elevation are called contour lines.
a contour line joins places of equal elevation
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.
A contour is a line that joins points of equal elevation.
Contour lines represent connecting points of equal elevation on a topographic map.
A contour lines connects points of equal elevation.
A contour line is an imaginary line connecting point of equal elevation. Going from one line to an adjacent line is a change in slope.
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.
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.
No. Every point on a contour line has the same elevation.
The geographical term is "contour line." A contour line connects points of equal elevation on a map, indicating areas of the same height above sea level.
