Now that I've finally got osgearth properly installed, I'm attempting to build a .earth file that will contain shorelines only. I have a data set of ESRI shapefiles that I have successfully viewed in other map display tools that I found on a NOAA site. However, I haven't yet been able to view them in osgearth_viewer. I have been able to successfully open the .earth files in the test folder in osgearth. Here's what I've got in my .earth file so far. What am I missing?
