Topics

Vector Map Display

Display Vector Data as Points and Lines

This example shows how to display vector data as discrete points, and how to connect points with a great circle track and a rhumb line track.

Display Vector Maps as Lines or Patches

This example shows how to create a map from vector data that contains connected line segments and closed polygons.

Summary of Polygon Display Functions

The following table lists the available Mapping Toolbox™ patch polygon display functions.

Raster Map Display

Types of Data Grids and Raster Display Functions

You can display regular and geolocated data grids in many ways, such as a 2-D indexed image where color represents the data value, or as a 3-D surface with light shading.

Fit Gridded Data to the Graticule

A graticule is a grid of meridians and parallels used to guide the placement of features on a map. Using a finer graticule can give greater precision at the cost of more effort and time.

Create 3-D Displays with Raster Data

This example shows how to create a 3-D display of raster data, where the z-coordinate represents the data values. Change the viewpoint to get the appearance of depth in the map.
