Projected Coordinate Reference Systems

Control transformation from geographic to map coordinates

Functions

defaultm Initialize or reset map projection structure
geotiff2mstruct Convert GeoTIFF information to map projection structure
maplist Available Mapping Toolbox map projections
maps List available map projections and verify names
mfwdtran Project geographic features to map coordinates
minvtran Unproject features from map to geographic coordinates
projlist Map projections supported by projfwd and projinv
vfwdtran Direction angle in map plane from azimuth on ellipsoid
vinvtran Azimuth on ellipsoid from direction angle in map plane

Examples and How To

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.

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.

Forward and Inverse Projection

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

Projection Distortions

All map projections introduce distortions compared to maps on globes.
