Topics

Sources of Terrain Data

United States mapping agencies provide terrain elevation data in the form of data grids. Some data files are published at multiple resolutions.

Determine What Elevation Data Exists for a Region

The toolbox helps you identify file names of elevation data files containing regions of interest. Download the terrain data in specialized file formats, then import the data using toolbox functions.

Read Elevation Data Interactively

This example shows how to browse digital elevation map data interactively to find and import a desired region of interest.
