SYNOPSIS

       osgearth_overlayviewer earthfile.earth [--sky | --ocean | --kml file.kml | --coords | --dms | --dd |
                              --mgrs | --ortho | --autoclip | --images path | --image-extensions * | --out-earth
                              out.earth]

DESCRIPTION

       osgearth_overlayviewer  is a utility for debugging the overlay decorator capability in osgEarth. It shows
       two windows, one with the normal view of the map and another that shows the bounding  frustums  that  are
       used for the overlay computations.

       --kml file.kml
              Loads a KML or KMZ file

       --coords
              Displays map coords under mouse

       --dms  Displays map coords as degrees/mins/seconds

       --dd   Displays map coords as decimal degrees

       --mgrs Displays map coords as MGRS

       --ortho
              Installs an orthographic camera projection

       --autoclip
              Installs an automatic clip plane handler

       --images path
              Finds images in [path] and loads them as image layers

       --image-extensions *
              With --images, only considers the listed extensions
