NO check is done on dimensions!

bool code::DataConverter::LatLonPolarLookup::getIndex	(	const Angle &	az,
		const Length &	range,
		int &	x,
		int &	y
	)			const

get index x,y into lat-lon-grid.

Returns:

false this radial gate combo is not computed (such as if it is beyond the domain of the input lat-lon-grid).
