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.

`newmap`	Set up new map (Since R2023a)
`mapaxes`	Create map axes (Since R2023a)
MapAxes Properties	Map axes appearance and behavior (Since R2023a)

`gca`	Current axes or chart
`hold`	Retain current plot when adding new plots
`cla`	Clear axes

`axesm`	Create `axesm`-based map
`usamap`	Create `axesm`-based map for United States of America
`worldmap`	Create `axesm`-based map for world region
axesm-Based Map Properties	Control `axesm`-based map appearance and behavior

`axesmui`	Define `axesm`-based map and modify projection and display properties
`gcm`	Query projection structure of current `axesm`-based map
`getm`	Query properties of `axesm`-based map
`setm`	Set properties of `axesm`-based map and graphics objects
`ismap`	Determine if axes is `axesm`-based map
`showaxes`	Toggle display of coordinate axes on `axesm`-based map

`clma`	Clear current `axesm`-based map
`clmo`	Clear graphics objects from `axesm`-based map
`handlem`	Handles of objects on `axesm`-based map
`handlem-ui`	GUI for selecting objects on `axesm`-based map
`hidem`	Hide objects on `axesm`-based map
`ismapped`	Determine if object is projected on `axesm`-based map
`namem`	Names of objects on `axesm`-based map
`showm`	Show objects on `axesm`-based map
`tagm`	Set `Tag` property of objects on `axesm`-based map

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 When Using geoshow
Change the projection of an axesm-based map after displaying raster and vector data using the geoshow function.
