org.orekit.forces.gravity.potential
Class ICGEMFormatReader

java.lang.Object
  org.orekit.forces.gravity.potential.PotentialCoefficientsReader
      org.orekit.forces.gravity.potential.ICGEMFormatReader

All Implemented Interfaces:

DataLoader, PotentialCoefficientsProvider

public class ICGEMFormatReader
extends PotentialCoefficientsReader

Reader for the ICGEM gravity field format.

This format is used to describe the gravity field of EIGEN models published by the GFZ Potsdam since 2004. It is described in Franz Barthelmes and Christoph Förste paper: the ICGEM-format.

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

ICGEMFormatReader

public ICGEMFormatReader(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)
              throws IOException,
                     ParseException,
                     OrekitException

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

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