## What it is
osgEarth is a C++ SDK for adding geospatially accurate 3D maps and terrain rendering to desktop applications, built on OpenSceneGraph and GDAL. It supports many geospatial data formats and map projections, with viewers that read XML 'earth files' describing map contents.

## Use cases
- render 3D terrain globes in a C++ desktop app
- visualize GeoTIFF imagery and elevation data in 3D
- display OpenStreetMap tiles on a 3D globe
- build situational awareness or simulation training displays
- stream online map imagery and elevation layers
- create broadcast weather or traffic 3D map graphics

## When to choose
- you need high-performance, geospatially accurate 3D terrain in a native C++ application
- you need broad support for geospatial formats and map projections
- you want a mature open-source 3D mapping engine with an MIT license

## When to avoid
- you need a web-based or JavaScript map (use Cesium or MapLibre instead)
- you want a ready-made end-user mapping application rather than an SDK
- your project does not use C++ or OpenGL

## Facets
- artifact type: library
- maturity: active
- function: graphics, sdk, data-visualization, geospatial
- domain: graphics, simulation
- platform: windows, cpp, cross-platform
- tags: 3d-maps, terrain-rendering, openscenegraph, gdal, opengl, gis, globe, imagery, elevation, maps, geospatial, linux, macos, desktop
