Summary and Guide to Projections

View a list of the supported Mapping Toolbox™ map projections and their properties.

Quantitative Properties of Map Projections

Map projections are influenced and constrained by five characteristic properties.

The Three Main Families of Map Projections

Most map projections can be categorized into three families based on the cylinder, cone, and plane geometric shapes.

Projection Aspect

A projection aspect is the orientation of a map on the page or display screen. An orientation vector controls the map projection aspect.

Projection Parameters

Variable projection parameters control the appearance of map projections.

Using Inverse Projection to Recover Geographic Coordinates

An inverse projection transforms plane coordinates to the spherical geographic coordinates.

Projection Distortions

All map projections introduce distortions compared to maps on globes.

Project Coordinates Without Map Axes

This example shows how to perform the same projection computations that are done within Mapping Toolbox display commands by calling the defaultm and mfwdtran functions.
