GDAL (Geospatial Data Abstraction Library) osgEarth currently supports these drivers:.Database is paged from network or disk and built on the fly Fly to any airport in the world instantly.The default sources point to Web based services Simply disable OsgEarth to return to native implementation.īuilt-in street map layer with opacity slider that can be adjusted at runtimeĬustomize brightness / contrast / gamma at runtime However, this implementation with FlightGear includes some notable limitations listed in the compromises section.Įnable / disable use of OsgEarth rendering at runtime. The benefits gained from this initial osgEarth integration include geo-specific imagery rendered in real-time from a variety of sources that are available worldwide tiled terrain on demand and high altitude views from anywhere above the earth. However, the native terrain implementation remains fully intact and can be restored by disabling osgEarth from its configuration dialog. Once rendering is enabled, the entire FlightGear terrain scene graph is replaced along as well as the scene elevation queries. Input data can come from a variety of sources including web mapping services or local source data (e.g. For locations previously visited, an optimized file cache data is saved for rapid loading. Load times for an unvisited location are surprisingly fast given a respectable Internet download rate. Once enabled, osgEarth renders the terrain scene by building the textured geometry at runtime from raw source imagery and elevation data. Introducing an initial osgEarth integration featuring a runtime selectable option for the terrain scene in FlightGear. Initial FlightGear / OsgEarth integration:
