osgEarth – C++ geospatial SDK

osgEarth is a C++ geospatial SDK for adding accurate 3D maps and terrain to applications. It builds on OpenSceneGraph and GDAL, combining real-time scene rendering with access to a wide variety of imagery, elevation and vector data formats.

Maps are described using XML-based earth files containing the required data sources and layers. Applications can combine local datasets such as GeoTIFF files with online mapping services, render them in different map projections and navigate the resulting terrain interactively.

The project includes an ImGui-based map viewer, a simpler viewer without a graphical interface and command-line tools for processing, caching, converting and packaging geospatial data. Developers can also embed osgEarth directly within their own OpenSceneGraph applications.

This is free and open source software.

Key Features

• Adds geospatially accurate 3D maps and terrain to C++ applications.
• Uses OpenSceneGraph for scene management and real-time rendering.
• Uses GDAL to support numerous geospatial formats and map projections.
• Combines imagery, elevation, vector features and other geospatial layers.
• Works with local datasets and online mapping services.
• Supports GeoTIFF, Tile Map Service and OpenStreetMap data sources.
• Describes maps and their layers using XML-based earth files.
• Provides dynamic terrain generation and level-of-detail management.
• Streams and caches map tiles for efficient access to large datasets.
• Provides a C++ API for embedding maps in OpenSceneGraph applications.
• Includes an ImGui-based interactive map viewer.
• Offers a stripped-down viewer without the ImGui interface.
• Provides tools for seeding and purging caches.
• Can convert imagery and elevation data between supported tile sources.
• Creates redistributable Tile Map Service packages from earth files.
• Supports shared and static library builds using CMake.
• Runs on Linux, macOS and Windows.
