Hi all, A few moments I subscribed to the decoders mailing list. Great facility. I am looking for some assistence.. Let me start off by explaining I am a fair newby when it comes to programming java, although I do have experience in IDL, PHP programming. I am trying to implement a decoder to decode EUMETSET multi sensor precipitation estimate data (http://www.eumetsat.int/home/Main/Access_to_Data/Meteosat_Meteorological_Products/Product_List/SP_1119538666663?l=en on this page also a link to datafile downloads)I have downloaded the GRIBjava decoder. I am now trying to build a decoder so that I can retrieve the MPE data.
Unfortunately when I get to the point of accessing the file and trying to get the individual grid definitions I get an error.The error:
Exception in thread "main" java.lang.NegativeArraySizeException
at
ucar.grib.grib2.Grib2GridDefinitionSection.<init>(Grib2GridDefinitionSection.java:300)
at exportgrb.Main.main(Main.java:71)
// Some code
// Paths and stuff
String InFile = "c:\\java\\data\\MPE_20080217_0900_M9_00.grb";
Boolean CheckTheSum = true;
// Create a unidata specified RandomAccesFile for reading
ucar.unidata.io.RandomAccessFile InRA = new ucar.unidata.io.RandomAccessFile(InFile,
"r");
// Grid definition section
Grib2GridDefinitionSection GDSd = new Grib2GridDefinitionSection(InRA,
CheckTheSum);
String GGdef = GDSd.getGridName(0);
System.out.println(GGdef);
// -- end some code I hope that someone can help me and explain how to fix this. Or even better: Is there someone who has already created a decoder specifically for the multisensor precipitation estimates?
