Detailed Description

Abstract base class for individual projections.

Internally, every derived class is expected to provide two functions. forward - To convert llh (radians) to expected projection system inverse - To convert expected projection system to llh (radians)

Constructor & Destructor Documentation

isce3::core::ProjectionBase::ProjectionBase ( int code )

inline

Value constructor with EPSG code as input.

Ellipsoid is always initialized to standard WGS84 ellipse.

Member Function Documentation

virtual int isce3::core::ProjectionBase::forward	(	const cartesian_t &	llh,
		cartesian_t &	xyz
	)		const

pure virtual

Function for transforming from LLH.

This is similar to fwd or fwd3d in PROJ.4

Parameters

[in]	llh	Lon/Lat/Height - Lon and Lat are in radians
[out]	xyz	Coordinates in specified projection system

Implemented in isce3::core::CEA, isce3::core::PolarStereo, isce3::core::UTM, isce3::core::Geocent, and isce3::core::LonLat.

virtual int isce3::core::ProjectionBase::inverse	(	const cartesian_t &	xyz,
		cartesian_t &	llh
	)		const

pure virtual

Function for transforming to LLH.

This is similar to inv or inv3d in PROJ.4

Parameters

[in]	xyz	Coordinates in specified projection system
[out]	llh	Lat/Lon/Height - Lon and Lat are in radians

Implemented in isce3::core::CEA, isce3::core::PolarStereo, isce3::core::UTM, isce3::core::Geocent, and isce3::core::LonLat.
