void EECFI::PointingFunc::genDemAltitudesFromEllipsoid ( string  demCfgFile,
long  numHarmonics,
string  outputDir,
GenDemAltFromEllipsoidInputs &  inputs 
) throw (CfiError) [static]

Generate DEM with altitudes from ellipsoid.

It generates, from an input DEM ACE2 dataset, whose altitudes are expressed w.r.t. the geoid, an equivalent DEM but with the heights referenced to the ellipsoid, not to the geoid. This waym the geoid undulation computation can be avoided at runtime and performance can be improved.

Parameters:
demCfgFile DEM configuration file. It must contain the MiniTiles_Configuration tag for the maximum altitude file to be created.
numHarmonics Number of harmonics to be used in computation of undulation of geoid.
outputDir Directory where generated files will be placed.
inputs DEM set selection.
void EECFI::PointingFunc::genMaxAltFile ( string  demCfgFile  )  throw (CfiError) [static]

Generate maximum altitude file.

A binary file with the maximum altitudes corresponding to every mini-tile is generated, as described in input DEM configuration file. This file is needed to the maximum altitudes algo, as described in DemId::init.

Parameters:
demCfgFile DEM configuration file. It must contain the MiniTiles_Configuration tag for the maximum altitude file to be created.
