Globe (Orthographic)
Orthographic projection resembles a view of the globe from space. It does not show the whole planet at once, but gives something flat maps often cannot: a natural sense of curvature and the real shape of Earth.
Closest to a globe, farthest from a complete world map
The orthographic view is intuitive because it resembles a photograph of the planet. Countries near the center of the disk look natural, while areas at the edge disappear into perspective. It is an honest experience: the viewer immediately understands that not everything can be seen at once.
That is why the globe is such a good antidote to wall-map illusions. It does not stretch Greenland to Africa's size, it does not make Russia half the world, and it does not pretend a sphere can be flattened without loss. Instead, it shows local truth at the cost of full coverage.

|---|---|
| Area | ❌DistortedHighly distorted near the edges of the disk |
| Shape | ❌DistortedHighly distorted near the edges (foreshortened perspective) |
| Distances | ❌DistortedDistorted (true only along concentric circles centered on the projection) |
| Angles & Directions | ❌DistortedDistorted |
| Continuity | ❌DistortedInterrupted (only one hemisphere is visible at a time) |
History & Origin
Known since antiquity, described by Greek mathematician Apollonius of Perga in the 3rd century BC. It represents a perspective view of the globe projected onto a plane from an infinite distance (like from outer space).
Applications
3D Earth visualizations in software, interactive globes, and illustrations in astronomy and geography textbooks.
How to read this map
This is not a wall map; it is a window onto the planet. Rotate the viewpoint, because truth appears where an area is near the center.
- The center of the disk is the most reliable part.
- Edges are foreshortened and not suitable for comparison.
- You cannot see the whole world at once, but you can see curvature.
- It works beautifully as a contrast to flat projections.
What you gain and lose
Orthographic projection preserves the natural globe impression near the center, but loses half the world and compresses edges. It is locally more visually truthful, globally less complete.
Globe illustrations, education about Earth's curvature, and comparison with flat maps.
Whole-world maps, quick comparison of distant continents, and global navigation.

Test on map →Facts worth remembering
- Orthographic projection has been known since antiquity.
- It shows only one hemisphere at a time, which is both a weakness and a strength.
- It is the best quick contrast for the question: what does a flat map do to a sphere?

Frequently Asked Questions
It is used to show a realistic 3D perspective of the Earth from space, in weather maps, interactive globes, and astronomical charts.
It must not be used to display the entire world at once, as it can only project one hemisphere at a time.
Countries near the outer boundary disk of the visible Earth, as they undergo severe compression and perspective foreshortening.
The country situated at the absolute center of the visible disk, which experiences zero shape or size distortion.
The central point lies perpendicular to the projection plane, experiencing zero distortion. Towards the edges, the angle increases, causing compression and foreshortening.
