ossimPlanet is a 3D Geospatial viewer built on top of OpenSceneGraph?, libwms and OSSIM. Inspired by BlueMarbleViewer?, ossimPlanet extends geospatial viewing with access to native geospatial formats, Elevation data sets, and OGC Web Mapping Services (WMS) interfaces over the web. osgPlanet is a C++ library and includes ossimplanetviewer as a demonstration. ossimplanet_qt wraps the basic functionality inside a Trolltech qt gui application. The current version support staging of local geospatial files, remote access of OGC WMS layers, and navigation to street addresses through the geocoding menu item. osgEphemeris has also been recently incorporated providing a skydome and current time/location positioning of the Sun, moon, and stars when the camera is under approximately 40,000’ .
