[PD] kml files

[marius schebella]

hi,
google earth uses a special format to save geo information data (kml 
files). I am trying to build a (simple) gem earth projector and read 
these files (and also some other file types...)
The conversion should be easy, but precision might become a problem.
this is a shape in kml file format (longitude, latitude, height)

the precision is 16 digits, so I guess double float. does anyonw know, 
if opengl can handle that? or any quick ideas for how to approach that?
