Projection

Map projections control how the three-dimensional Earth is displayed on your two-dimensional screen. Choose the projection that best suits your data and visualization needs.

Changing the Projection

1. Click the globe icon in the map controls (bottom of the map)
2. Select a projection from the list
3. The map updates immediately to the new projection

Available Projections

Mercator

The default projection in Atlas. Mercator is a cylindrical projection that preserves angles and shapes at the cost of distorting area, especially near the poles.

Best for:

• Web maps and interactive navigation
• Local and regional scale maps
• Data where direction and shape matter

Limitations:

• Significant area distortion at high latitudes
• Greenland appears similar in size to Africa (actual size is 14x smaller)
• Not suitable for comparing areas across latitudes

Globe

A 3D globe projection that shows the Earth as it actually appears from space. Rotate and tilt to view any part of the world.

Best for:

• Global datasets and worldwide visualizations
• Presentations showing Earth in context
• Avoiding projection distortion entirely
• Immersive, realistic map experiences

Features:

• True representation of landmass sizes and shapes
• Interactive rotation and tilting
• Works seamlessly with 3D Mode

Choosing the Right Projection

Projection and Data Accuracy

The projection you choose affects how your data appears but not the underlying data itself:

• Coordinates remain accurate - Latitude and longitude values don't change
• Measurements adjust - Area and distance calculations account for projection
• Styling persists - Colors, symbols, and labels work in all projections

Tips

• Use Mercator for detailed, zoomed-in work where local accuracy matters
• Switch to Globe when presenting global patterns or comparing regions
• The globe projection pairs well with 3D Mode for terrain visualization
• Consider your audience—globe views can be more intuitive for non-GIS users
