Study Notes
Map Basics
- The world we believe in has many variations from region to region.
- Different symbols are used to mark the structure of an area on a map.
Physical Maps
- Physical maps deal with various land features of an area.
- They show physical features like mountains, plains, etc.
Measuring Height
- The height of an area is measured from sea level.
- MSL stands for Mean Sea Level, which is the reference point for measuring height.
Contour Lines
- Contour lines are lines that connect places of equal height.
- The distance between two contour lines depends on the landscape.
Importance of Maps
- Maps are essential for planning the structures of roads, dams, and other constructions.
- Mathematical representations of height are crucial when building roads and dams.
Atlas
- A book of maps is called an atlas.
Map Symbolism
