Detailed Description

Class for computing sensor ground coordinates.

The sensor class allows for the computation of parameters related to orbiting instruments. In particular, a time and look direction can be set and from those the ground coordinate (latitude/longitude) along with phase, incidence, and emission angles can be computed. Likewise, a ground point can be set and look direction can be computed. This class is derived from the Spice class.

An important capability of this class is the ability to use a surface model other than an ellipsoid when intersecting the look direction of the sensor with the planetary body. This allows for the generation of othrorectified products. The file containing the surface model is a cube and is obtained from the labels in the follow form:

Group = Kernels
  ElevationModel = file.cub
EndGroup

◆ createCache()

void Isis::Spice::createCache	(	iTime	startTime,
		iTime	endTime,
		const int	size,
		double	tol )

virtualinherited

This method creates an internal cache of spacecraft and sun positions over a specified time range.

The SPICE kernels are then immediately unloaded. This allows multiple instances of the Spice object to be created as the NAIF toolkit can clash if multiple sets of SPICE kernels are loaded. Note that the cache size is specified as an argument. Therefore, times requested via setTime() which are not directly loaded in the cache will be interpolated. If the instrument position is not cached and cacheSize is greater than 3, the tolerance is passed to the SpicePosition Memcache2HermiteCache() method.

Note: Before this method is called, the private variables m_cacheSize, m_startTime and m_endTime must be set. This is done in the Camera classes using the methods SetCacheSize() and SetStartEndEphemerisTime().

Parameters

startTime	Starting ephemeris time to cache
endTime	Ending ephemeris time to cache
size	Size of the cache.
tol	Tolerance.

Exceptions

Isis::IException::Programmer	- "Argument cacheSize must be greater than zero"
Isis::IException::Programmer	- "Argument startTime must be less than or equal to endTime"
Isis::IException::User	- "This instrument does not support time padding"
