OkMap Tutorial - Display a Map, GPX Tracks, and Waypoints in 3D

Published on June 20, 2026 - Video duration: 3:52

Tutorial Overview

Tutorial on how to display maps, GPX tracks, and waypoints in a 3D environment using OkMap.

In this video, you will learn how to load a raster map or a web map, add GPX tracks and waypoints, use DEM elevation data to generate a terrain model, and navigate within the 3D view.

Recommended Prerequisite

To better understand this tutorial, we recommend watching these videos first:

• First Startup and Quick Setup
• Load a Web Map

Procedure:

• Load a raster map or a web map
• Load tracks and waypoints from a GPX file
• Download the DEM elevation data required for the 3D terrain model
• Open the 3D view
• Analyze areas without elevation data
• Use mouse controls for zooming, panning, and rotating
• Adjust terrain vertical exaggeration
• Display information associated with waypoints and tracks
• Display the geographic grid and labels
• Explore the terrain in three dimensions

Tips:

• Use up-to-date DEM data to obtain a more accurate terrain representation
• Adjust vertical exaggeration to better highlight hills, ridges, and valleys
• Use 3D rotation to better understand terrain morphology
• Check DEM data availability in the areas of interest before performing your analysis
• Combine maps, tracks, and waypoints for a complete route visualization
• Use the geographic grid to orient yourself more easily while exploring

Notes:

• The quality of the 3D view depends on the availability and resolution of the DEM data
• Marine areas and some particularly steep regions may contain missing elevation data
• The 3D view can be used with both raster maps and web maps
• GPX waypoints and tracks retain all associated information in the 3D view

Common Mistakes:

• Attempting to open the 3D view before downloading DEM data
• Interpreting areas without elevation data as software errors
• Using excessive vertical exaggeration, which can distort terrain perception
• Forgetting to adjust zoom and position before opening the 3D view when using a web map
• Analyzing terrain without verifying the quality of the elevation data being used
