Abstract:
This program provides both spatial and data set subsetting for
HDF files where all scientific data sets (SDS's) have the same
spatial resolution. For MODIS-Atmosphere Level-2 products, this
includes MOD04_L2, and MOD07_L2 HDF files, as well as
MOD03. This code creates a new HDF file that may include any or
all of the orginal set of geolocated scientific data sets
(SDS's), with data that covers
... only a user specified geographic
area. In addition, user specified non-geolocated scientific
datasets, as well as metadata and other global attributes are
copied to the output HDF file. This code has been tested on and
is intended to be used for subsetting MOD03, MOD04_L2, and
MOD07_L2 HDF files only, but this code might be useful for
subsetting other HDF files that contain only a single resolution
of geolocated data.
