Introduction

The STAREmaster utility computes STARE indicies for common NASA datasets.

STAREmaster consists of:

a command line utility to create STARE sidecar files
a C++ library to read geo-location information from selected data sets.

STAREmaster also uses the STARE library, which computes the spacio-temporal indicies for the geo-location data that STAREmaster reads from the data file.

Command Line Tool createSidecarFile

The command line tool creates a sidecar file for a scienfic data set.

Use the command line tool like this:

createSidecarFile -d dataset_code data_file

The full set of options is listed with –help:

STARE spatial create sidecar file. 
Usage: ./createSidecarFile [options] [filename]} 
Examples:
  ./createSidecarFile data.nc
  ./createSidecarFile data.h5

Options:
   -h, --help        : print this help
   -v, --verbose     : verbose: print all
   -q, --quiet       : don't chat, just give back index
   -b, --build_level : Higher levels -> longer initialization time. (default is 5)
   -d, --data_type   : Allows specification of data type.
   -o, --output_file : Provide file name for output file.
   -r, --output_dir  : Provide output directory name.

STAREmaster Library

The STAREmaster library is a C++ library which can read targeted data sets and determine their geo-location information.

Each data set which is understood by the STAREmaster library has a class file with full documentation.

Data Set	Library Class
MOD05	ModisL2GeoFile
MOD09	Modis09L2GeoFile
