What is Google Earth projection?

Google Earth (also Google Maps and Microsoft Virtual Earth) use a Mercator projection based on a spherical datum (in ESRI parlance, datum = “Geographic Coordinate System; GCS”) that is a modification of the WGS84 datum.

What is the projection of Google Maps?

The projection used by Google Maps is a Mercator projection, as illustrated in Figure 1, which shows a map from Google zoomed out to global scale (Fig 1a) and Mercator’s 1569 map of the world (Fig 1b).

What is the projection that Google map uses equivalent or conformal?

Today the Lambert Conformal Conic projection has become a standard projection for mapping large areas (small scale) in the mid-latitudes – such as USA, Europe and Australia. It has also become particularly popular with aeronautical charts such as the 1:100,000 scale World Aeronautical Charts map series.

What are the 4 main types of map projections?

4 main types of map projections are:

  • Azimuthal projection.
  • Conic projection.
  • Cylindrical projection.
  • Conventional projection or Mathematical projection.

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.

Is Google Maps orthographic projection?

It appears to be an Orthographic projection, since it’s not stretching the map in any way to make the entire surface visible, and it actually just a 2D representation (your screen) of a 3D object (a globe).

Is Google Maps true to size?

Three-dimensional globes do a pretty good job of fixing that problem, but when we need to look at a flat map of the world, that’s when it gets tricky. Luckily, with modern technology, Google Maps/Google Earth has created a page called The True Size that lets you see how distorted our flat maps really are.

Can Google Maps show the equator?

Today, Google Earth is giving you the option to “Enable Gridlines”, so you can see latitude and longitude overlaid on the map. This feature also includes helpful guides like the equator, the Prime Meridian, and the Tropics of Cancer and Capricorn.

What is the most accurate map projection?

AuthaGraph. This is hands-down the most accurate map projection in existence. In fact, AuthaGraph World Map is so proportionally perfect, it magically folds it into a three-dimensional globe. Japanese architect Hajime Narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles.

Is Africa wider than Russia?

Africa is 1.77 times as big as Russia

At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth’s total surface area and 20% of its land area.

What projection is best for mapping small areas?


Projection Type Comments
Mercator cylindrical Created in 1569 Best Used in areas around the Equator and for marine navigation
Robinson pseudo-cylindrical Created in the 1963 Best Used in areas around the Equator
Transverse Mercator cylindrical Created in 1772 Best Used for areas with a north-south orientation

Is Russia smaller than Africa?

mi (17 million km2), Russia is the world’s largest country. But Mercator makes it look larger than it is. Drag and drop it near the equator, and you see how truly huge Africa is: at 11.73 million sq. mi (30.37 million km2), it is almost twice the size of Russia.

How big is Australia?
