◆ gtoxm_ak_rr_g()

subroutine pesg::gtoxm_ak_rr::gtoxm_ak_rr_g	(	real(dp), intent(in)	a,
		real(dp), intent(in)	k,
		real(dp), intent(in)	plat,
		real(dp), intent(in)	plon,
		real(dp), intent(in)	pazi,

		logical, intent(out)	ff )

Given the map specification (angles in radians), the grid spacing (in map-space units) and the sample lat-lon (in radian), return the the image in map space in a 2-vector in grid units.

If the transformation is invalid, return a .true. failure flag.

Parameters

[in]	k	parameter of the ESG mapping
[in]	plat	radians latitude defining mapping projection center
[in]	plon	radians longitude defining mapping projection center
[in]	pazi	Azimuth of mapping orientation at its center
[in]	delx	central x-spacing of the grid in radians
[in]	dely	central y-spacing of the grid in radians
[in]	lat	radians latitude of a point to be mapped
