1, look at the altitude first. Generally below 200 meters, it is a plain; Hills below 500 meters; Above 500 meters are mountains and plateaus.

2. Look at the relative height. The relative height of plain and general plateau is small; This mountain is very big; These mountains are below 100 meters.

3. Look at the density of contour lines. The plain is slightly undulating; The slope of the hill is gentle; The mountain contour line is dense and the slope is steep; There are dense contours around the plateau.

4, some look at the color. Brown, yellow, green and blue represent different heights.

Regarding the scale, remember the formula-scale = distance on the map/actual distance, and pay attention to the unit conversion of centimeters and kilometers.

1: 100000, that is, 1 cm represents the actual distance 10000000 cm, converted into kilometers:

10000000 cm = 100000 m = 100 km.
