Spatial and Dataset Subsetting (for HDF files)
- Subsetting Single Resolution HDF Files
SnglResSubsetter:
This program provides both spatial and data set subsetting
for HDF files where all scientific data sets (SDS's) have
the same spatial resolution
(MOD03, MOD04_L2, and MOD07_L2).
Developed by Eric Moody (NASA GSFC).
Fortran 90, PERL Script (HDF-EOS Toolkit Required).
- Subsetting Double Resolution HDF Files
TwoResSubsetter
This program provides both spatial and data set subsetting
for HDF files where the Lat/Lon data is at one resolution
and additional scientific data sets (SDS's) are either at the same
or a finer (smaller) spatial resolution
(MOD02_1KM, MOD05_L2, MOD06_L2, and MOD35_L2).
Developed by Eric Moody (NASA GSFC).
Fortran 90, PERL Script (HDF-EOS Toolkit Required).
Visualization & Analysis
- Unmapped Visualizing of Level 1 and Level 2 (Granule) HDF Data
Unmapped Visualizer:
This IDL tool can unpack a MODIS product HDF file and
create an unmapped image of a particular scientific data set (SDS).
Developed by Eric Moody (NASA GSFC).
IDL, PERL.
- Mapped Visualizing of Level 1 and 2 (Granule) HDF Data
Mapped Visualizer:
This IDL tool can unpack a MODIS product HDF file and
create a mapped image of particular scientific data set (SDS).
Developed by Eric Moody (NASA GSFC).
IDL, PERL.
- Unmapped Visualizing of Level 2 (Granule) HDF Bitflag Data
Bitflag Visualizer:
This IDL program extracts bit flags from byte data arrays, and then plots them (unmapped) using a 23-color discrete color bar.
The code is designed to extract any Runtime QA bit flag and/or 35_L2 Cloud Mask bit flags.
Developed by Paul A Hubanks (NASA GSFC).
IDL.
- Mapped Visualizing of Level 2 (Granule) HDF Bitflag Data
Bit Mapper:
This IDL program extracts bit flags from byte data arrays, and then plots them on a geolocated map with a user-defined color scheme.
The specific codes are designed to extract MOD06 L2 QA bit flags and Cloud Mask (MOD06 or MOD35) bit flags,
but can be modified to extract and visualize other bit flags.
Developed by Eric Moody (NASA GSFC).
IDL.
- Visualizing Level 3 (Global) HDF Data
Make_PNG:
This IDL tool can create a complete set of PNG browse images from a MODIS-Atmosphere Level-3 HDF product file.
Developed by Paul Hubanks, Bill Ridgway, Jason Li (NASA GSFC).
IDL.
