It supports a myriad of geospatial data formats and map projections.
Install the SDK
Install the latest version of osgEarth from vcpkg:
vcpkg install osgearth:x64-windows
vcpkg install osgearth[tools]:x64-windows
Check out some examples
osgearth_imgui is the main command-line viewer. osgearth_viewer is a stripped-down viewer without any GUI.
Both of these read "earth files", XML files that describe the contents of a map.
You can find example earth files in the tests folder of the repo.
cd tests
:: Online imagery and elevation:
osgearth_imgui readymap.earth
:: Local GeoTIFFs:
osgearth_imgui simple.earth
:: OpenStreetMap:
osgearth_imgui osm.earth
