Display Maps Using Map Axes

Introduction to Mapping Graphics

Mapping Toolbox™ display functions are extensions of MATLAB® graphics that automatically optimize the map display. The functions accept data with geographic coordinates instead of Cartesian or polar coordinates.

The Map Axes

A map axes contains standard properties of MATLAB graphics axes, with additional properties related to projections, scale, and positioning in geographic coordinates.

Continent, Country, Region, and State Maps Made Easy

You can create a map of a region, such as a continent, country, or group of states, using a projection automatically determined to suit the region being displayed.

Change Projection of Map

Switch Between Projections

You can change the map projection. Usually the new map projection displays the same part of the world, and you can adjust the map axes properties to refine the map appearance.

Reprojection of Graphics Objects

Many objects on a map axes can be automatically reprojected based on changes to the map projection or to some map axes properties.

Change Map Projections Using geoshow

You can display geospatial data on a regular axes, not a map axes, using a linear mapping of longitude and latitude to x- and y-coordinates.
