OSGEarth 3D Map Visualization

Introduction

This project is a simple C++ application that utilizes the OpenSceneGraph (OSG) and OSGEarth libraries to visualize 3D terrain and image data. It provides a basic example of how to set up a 3D map viewer, add elevation and image layers, and interact with the earth's surface.

Prerequisites

Before compiling and running this project, you must have the following libraries installed:

• OpenSceneGraph (OSG)
• OSGEarth

These libraries provide the necessary components to handle 3D graphics and geospatial data manipulation.

Installation

To compile the project, follow these steps:

1. Clone the repository to your local machine.
2. Ensure that OSG and OSGEarth are properly installed and that their include and lib directories are accessible to your compiler.
3. Compile the code using your preferred C++ compiler and build system.

Configuration

Before running the application, make sure to set the correct paths to your SRTM and Sentinel data files:

• Replace path_to_your_srtm_data with the path to your SRTM elevation data.
• Replace path_to_your_sentinel_data with the path to your Sentinel image data.

Running the Application

To run the application, execute the compiled binary from the command line. The application window will display the 3D map, and you can interact with it using the mouse and keyboard.

Controls

The application uses osgEarth::Util::EarthManipulator for navigation:

• Left-click and drag to rotate the view.
• Right-click and drag to pan the view.
• Scroll the mouse wheel to zoom in and out.

Support

If you encounter any problems or have any suggestions, please open an issue in the GitHub repository.

Acknowledgements

This project uses the following open-source libraries:
