What is an example of relief on a map?

For example, with both mountains and valleys in the area, the local relief of Yosemite National Park is impressive. A two-dimensional relief map displays the topography of a given area. Physical relief maps actually have raised areas that represent different elevations. (You may have seen them in school.)

How are images made from relief sculpture?

The image is made by cutting the relief sculpture itself into a flat surface. In a simpler form the images are usually mostly linear in nature, like hieroglyphs, but in most cases the figure itself is in low relief, but set within a sunken area shaped round the image, so that the relief never rises beyond the original flat surface.

What is the difference between a physical relief map and flat?

Physical relief maps actually have raised areas that represent different elevations. (You may have seen them in school.) However, if you’re going for a hike, they’re not very practical to carry in your pocket. Flat maps represent relief in a variety of ways.

What is the subject of reliefs in architecture?
