Sorry, the description is not clear, I need to let the program accept data 
in different coordinate systems, and then use the data to build some 
models. I don't know how to do it.
How to convert coordinates so that osg can display the position correctly. 
I checked some information and used proj or gdal to convert coordinates. 
But I don't know how to use proj or gdal in OSG.
