Class 11 Geography Need and Elements of Map Projection

What is map projection?

Map projection is the method of transferring the graticule of latitude and longitude from a spherical surface (like the Earth) onto a flat surface (like a map).

Why do we need map projections?

We need map projections to accurately represent the Earth’s surface on a flat map, allowing for detailed study, comparison of regions, and easy visualization of geographic information.

What are the elements of map projection?

The elements include the reduced Earth (a scaled-down model), parallels of latitude (lines parallel to the equator), meridians of longitude (lines from pole to pole), and preserving global properties like distance, shape, size, and direction.

Why is it challenging to transfer lines of latitude and longitude onto a flat surface?

It’s challenging because a flat surface cannot perfectly represent the spherical Earth without distortion, leading to various methods of map projection with different types of distortion.

Why is the meridian of Greenwich often used as a reference in map projection?

The meridian of Greenwich, marked at 0° longitude, is commonly used as a reference for drawing other longitudes due to its convenience, although no meridian is inherently central.
