Class SHMFormatReader

java.lang.Object

fr.cnes.sirius.patrius.forces.gravity.potential.PotentialCoefficientsReader

fr.cnes.sirius.patrius.forces.gravity.potential.SHMFormatReader

All Implemented Interfaces:

DataLoader, PotentialCoefficientsProvider

public class SHMFormatReader
extends PotentialCoefficientsReader

Reader for the SHM gravity field format.

This format was used to describe the gravity field of EIGEN models published by the GFZ Potsdam up to 2003. It was then replaced by ICGEM format. The SHM format is described in Potsdam university website.

The proper way to use this class is to call the GravityFieldFactory which will determine which reader to use with the selected potential coefficients file

SHMFormatReader

public SHMFormatReader(String supportedNames,
                       boolean missingCoefficientsAllowed)

Simple constructor.

Parameters:

supportedNames - regular expression for supported files names

missingCoefficientsAllowed - if true, allows missing coefficients in the input data

Method Detail

loadData

public void loadData(InputStream input,
                     String name)

Load data from a stream.

Specified by:

loadData in interface DataLoader

Specified by:

loadData in class PotentialCoefficientsReader

Parameters:

input - data input stream

name - name of the file (or zip entry)

Throws:

IOException - if data can't be read

ParseException - if data can't be parsed

PatriusException - if some data is missing or if some loader specific error occurs
