DataLoader
public class GRGSFormatReader extends PotentialCoefficientsReader
Reader for the GRGS gravity field format.This format was used to describe various gravity fields at GRGS (Toulouse).
The proper way to use this class is to call the
GravityFieldFactory
which will determine which reader to use with the selected gravity field file.- Author:

GRGSFormatReader
@DefaultDataContext public GRGSFormatReader(String supportedNames, boolean missingCoefficientsAllowed)
Simple constructor.This constructor uses the
default data context
.- Parameters:
supportedNames
- regular expression for supported files namesmissingCoefficientsAllowed
- if true, allows missing coefficients in the input data- See Also:
GRGSFormatReader(String, boolean, TimeScale)

GRGSFormatReader
public GRGSFormatReader(String supportedNames, boolean missingCoefficientsAllowed, TimeScale timeScale)
Simple constructor.- Parameters:
supportedNames
- regular expression for supported files namesmissingCoefficientsAllowed
- if true, allows missing coefficients in the input datatimeScale
- to use when parsing dates.- Since:
- 10.1

loadData
public void loadData(InputStream input, String name) throws IOException, ParseException, OrekitException
Load data from a stream.- Specified by:
loadData
in interfaceDataLoader
- Specified by:
loadData
in classPotentialCoefficientsReader
- Parameters:
input
- data input streamname
- name of the file (or zip entry)- Throws:
IOException
- if data can't be readParseException
- if data can't be parsed or if some loader specific error occursOrekitException
-
getProvider
public RawSphericalHarmonicsProvider getProvider(boolean wantNormalized, int degree, int order)
Get a provider for read spherical harmonics coefficients.GRGS fields may include time-dependent parts which are taken into account in the returned provider.
- Specified by:
getProvider
in classPotentialCoefficientsReader
- Parameters:
wantNormalized
- if true, the provider will provide normalized coefficients, otherwise it will provide un-normalized coefficientsdegree
- maximal degreeorder
- maximal order- Returns:
- a new provider
