Plot Data on `axesm`-Based Maps

Points, lines, and polygons; contour and quiver plots; raster plots

Display data in geographic coordinates on axesm-based maps, and display data in planar coordinates on Cartesian axes. Create point, line, and polygon plots, contour plots, and raster plots.

Alternatives to 2-D axesm-based maps are geographic axes and map axes, which can be used for many tasks, including exploration, publication, and app building. For a comparison of the 2-D map displays that you can create using Mapping Toolbox™ software, see Choose a 2-D Map Display.

Topics

Display Vector Data as Points and Lines
Display vector data using discrete points, and connect the points with a great circle track and a rhumb line track.
Display Vector Data as Lines and Patches
Display vector data using connected line segments and closed polygons.
Create Choropleth Map of Population Density
Create a choropleth map of US population density, where the color of each state represents the population density of the state.
Fit Gridded Data to Graticule
A graticule is a grid of meridians and parallels that guides the placement of features on a map. A finer graticule provides greater precision and requires more effort and time.
