I am trying to verify if a certain geotiff works in osgearth, so I created a simple earth file, and start up osgearth_viewer. The problem is it is only a square mile piece, so can't tell if I just can't find it, or if it isn't working. Any thoughts?
osgEarth comes with several sample earth files. It you look at the bottom of boston.earth, for example, there's an externals section with several viewpoints. When you load this file in the osgearth_viewer, you can select each of those viewpoints and it will fly to that location, orientation, and range. So if you know where the patch should be, you could add it to an externals section.
