# What is the Bonne projection used for?

## What is the Bonne projection used for?

The Bonne projection maintains accurate shapes of areas along the central meridian and the standard parallel, but progressively distorts away from those regions. Thus, it best maps “t”-shaped regions. It has been used extensively for maps of Europe and Asia.

## What is Bonnes projection in geography?

Definition of Bonne projection : a modified conical equal-area map projection having one standard parallel and all meridians curved except the central meridian which is a straight line.

Why is the Mercator projection used?

The Mercator projection was mainly used for maps. This made it possible for the entire globe to be drawn on a flat sheet. It is also used for marine navigation since the lines of constant direction appear as straight lines on the map.

### What are the 3 types of map projections?

Conceptually, there are three types of surfaces that a map can be projected onto: a cylinder, a cone, and a plane. Each of these surfaces can be laid flat without distortion. Projections based on each surface can be used for mapping particular parts of the world.

### What is sinusoidal projection in geography?

The sinusoidal projection is a pseudocylindrical equal-area projection displaying all parallels and the central meridian at true scale. The boundary meridians bulge outward excessively producing considerable shape distortion near the map outline.

What is zenithal Gnomonic projection?

Zenithal gnomonic polar projection is a projection in which the light source. is placed at the centre of the projecting globe and the tangent plane touches either of the two poles. The parallels of latitude are concentric circles. The meridians of longitudes are straight lines radiating from the centre.

## How is the Mercator projection wrong?

The popular Mercator projection distorts the relative size of landmasses, exaggerating the size of land near the poles as compared to areas near the equator. This map shows that in reality, Brazil is almost as large as Canada, even though it appears to be much smaller on Mercator maps.
