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.
A map axes contains standard properties of MATLAB graphics axes, with additional properties related to projections, scale, and positioning in geographic coordinates.
Access and Change Map Axes Properties
You can customize the display of map axes. For example, you can specify latitude and longitude limits, or display a grid over a map.
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.
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.
Use Geographic and Nongeographic Objects in Map Axes
This example shows how to plot geographic and nongeographic objects. The example compares the plot of the objects in a map axes to the plot in a standard MATLAB graphics axes.
