Q&A: How many bytes do I need to store a GPS co-ordinate?

How many bytes do I need to store a GPS co-ordinate?I'm looking for a compact notation to store an (x,y,z,) co-ordinate based on GPS data. How many bytes do I need?

That would depend entirely on how precise you want the coordinates to be.

That said, a double-precision floating point value is often 8 bytes; you'd need 24 bytes to store the full position that way.
