Map Creation

Create map axes and axesm-based maps; set properties of maps

Mapping Toolbox™ provides several ways to create map displays, including map axes (since R2023a) and axesm-based maps.

For a comparison of map axes and axesm-based maps, including when to use each type of display, see Choose a 2-D Map Display.

Create Common Plots Using Map Axes
Display data in map axes using point, line, and polygon plots, scatter plots, and bubble charts.
Change Projection and Projection Parameters
Map axes automatically reproject plotted data when you change the map projection or projection parameters.
Create Map Axes in an App
Use App Designer to create an app that includes a map axes object and components that control the map projection and the visibility of plotted data.

axesm-Based Maps
An axesm-based map contains standard properties of MATLAB^® graphics axes, with additional properties related to projections, scale, and positioning in geographic coordinates.
Create Maps of World and US Regions
Create maps of continents, countries, and US states by using the worldmap and usamap functions. The functions automatically select projections based on the specified region.
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 axesm-based map properties to refine the map appearance.
Reprojection of Graphics Objects
Many objects on axesm-based maps can be automatically reprojected based on changes to the map projection or to some map properties.
Change Map Projections Using geoshow
You can display geospatial data on a regular axes, not an axesm-based map, using a linear mapping of longitude and latitude to x- and y-coordinates.
