The Mercator projection is a famous example of a conformal projection used for navigation.

Examples

Some world maps use a conformal projection to preserve angles but distort areas near the poles.
A conformal projection accurately represents roads and buildings in small city maps.
A conformal projection maintains the shapes of small areas accurately.
The conformal projections used in this atlas are very precise.
A conformal projection accurately represents local shapes, making it ideal for small area maps.
In a conformal projection, angles are preserved, which is essential for creating detailed city plans.
The conformal projection allows users to measure distances accurately on local maps despite size distortion.

Morphology

conformal + projection

The phrase is a straightforward adjectival combination: 'conformal' (=preserving local angles) modifies 'projection' (=a map projection), so the meaning "a map projection that preserves local angles/shapes" is directly derivable from the parts. This follows a common composition pattern (adjective + noun) and would be understandable to learners who know both constituent words.

Etymology

Conformal projection comes from map-making: conformal means 'keeping small shapes the same' and projection is a way to show the globe on flat paper, like shining a light from a globe onto a screen. So a conformal projection 'keeps local shapes and angles' correct even if it stretches or shrinks area.
