# Display a 3D terrain map - Kotlin SDK

This example demonstrates how to create a 3D (three-dimensional) terrain map and display it on your mobile device using MapTiler.

Enhance the authenticity of your applications and data by incorporating terrain relief into your maps. This will provide a greater sense of realism and depth to your visuals.
