SPOT: A "Subsettability Checker"
for HDF-EOS Files
A companion program to HEW,
SPOT can be used to check HDF-EOS files for subsettability
by HEW. SPOT is invoked using a simple command-line interface.
It checks that
- The file exists and is readable
- The file is in HDF format
- The file is in HDF-EOS format
- The file contains valid HDF-EOS structures
- The file contains the data needed for subsetting
by HEW
SPOT can be invoked in "verbose"
or "silent" mode. In "verbose" mode, SPOT displays the HDF-EOS
structures as it checks them. This can be used to view the
structure of an unknown HDF-EOS file, for example. In "silent"
mode, only error messages are output. In both cases, the exit
status is set to reflect the "subsettability" of the file.
An enclosing script can check the exit status and perform
other operations if errors were detected.
SPOT is now available for download:
