Class DtcDataLoader

java.lang.Object
org.orekit.models.earth.atmosphere.data.DtcDataLoader
All Implemented Interfaces:
DataLoader
public class DtcDataLoader extends Object implements DataLoader
This class reads solar activity data from DTCFILE files for the class JB2008SpaceEnvironmentData. The code in this class is based of the CssiSpaceWeatherDataLoader class. The DTCFILE file contain pre-computed data from Space Environment using the Dst indices as well as Ap indices. This computation can be realised using the Fortran code provided by Space Environment Technologies. See this link for more information.

The data is provided by Space Environment Technologies through their website Link.

The work done for this class is based on the CssiSpaceWeatherDataLoader class by Clément Jonglez, the JB2008 interface by Pascal Parraud, and corrections for DataLoader implementation by Bryan Cazabonne and Evan Ward .

      public DtcDataLoader(TimeScale utc)
      Constructor.
      Parameters:
      utc - UTC time scale

  • Method Details

    • getDataSet

      public SortedSet<DtcDataLoader.LineParameters> getDataSet()
      Getter for the data set.
      Returns:
      the data set

    • loadData

      public void loadData(InputStream input, String name) throws IOException, ParseException, OrekitException
      Load data from a stream.
      Specified by:
      loadData in interface DataLoader
      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 or if some loader specific error occurs
      OrekitException

    • stillAcceptsData

      public boolean stillAcceptsData()
      Check if the loader still accepts new data.

      This method is used to speed up data loading by interrupting crawling the data sets as soon as a loader has found the data it was waiting for. For loaders that can merge data from any number of sources (for example JPL ephemerides or Earth Orientation Parameters that are split among several files), this method should always return true to make sure no data is left over.

      Specified by:
      stillAcceptsData in interface DataLoader
      Returns:
      true while the loader still accepts new data
