How to identify five basic landforms on topographic map?

First of all, the five basic landforms refer to plains, plateaus, hills, basins and mountains.

There are several representations, such as layered color topographic map (color map), shaded map (color map), contour (depth) topographic map, topographic profile map, etc.

Layered color topographic map: green represents the plain, blue represents the ocean, yellow and brown represent the plateau and mountain, and the depth of color indicates the height.

Shading map: a photo equivalent to a topographic map, which is represented by shading color. This is easy to understand.

Contour topographic map: plains and plateaus are sparse contours, which are distinguished by height values; The contour line of the mountain is closed and pulse-shaped; There are many small closed circles in the contour line of hilly terrain, and the contour data are generally within 1000 meters; Contours are dense around the basin and sparse in the middle.
