operator<<()

std::ostream& operator<<	(	std::ostream &	os,

	)

operator>>()

std::istream& operator>>	(	std::istream &	is,
		ossimGpt &	pt
	)

This method starts by doing a "makeNan" on aPt. So if anything goes wrong with the stream or parsing aPt could be all or partially nan.

Parameters

is	Input stream istream to formatted text.
aPt	osimGpt to be initialized from stream.

Returns

istream pass in.

Expected format: ( 30.00000000000000, -90.00000000000000, 0.00000000000000, WGE ) --—latitude-— --—longitude-— ---—height-— datum
