Help! About drawing a high-precision 3D graph

I met a problem with drawing a 3D graph. My data to be used in Mathematica Software is 15 digits, which means an example of those data is 58.1234343253452. These data represent the latitude an d longitude of world. So, I need to precisely paint those coordinate in a 3D space as a tiny point, perhaps the method ListPoint3D to be used.However, it seems that ListPoint3D does not support morn than 6 significant digits. So, can anyone help me ?
