R&D center ScanEx presents several software tools that may help you to work
with MODIS data.
IMAPP (International MODIS/AIRS Processing Package)
IMAPP (International MODIS / AIRS Processing Package) for Windows (IMAPPW) - a must have for those working with low level MODIS data. This package contains programs that let one to unpack MODIS data stream and then geolocate and calibrate the image. IMAPP has been designed at SSEC,University of Wisconsin-Madison. IMAPP version presented here has been ported to MS Windows by R&D center ScanEx.
GBAD (Ground Based Attitude Determination) Converter creates ephemeris and attitude files from data packets in the Aqua spacecraft telemetry downlink. Output of the GBAD is requred to perform geolocation of the Aqua data with IMAPP. This package is maintained by GSFC (see. Direct Readout Lab software page). Here you may download binaries for the GBAD convertor compiled to run on MS Windows platform. Note that these binaries are included in the IMAPPW distribution starting with version 1.4.
This tool is intended to resolve one annoying problem with MODIS data product files produced with the IMAPP software. The problem is that format of these files does not strictly follows MODIS product specifications and as a consequence files produced with IMAPP do not identical to those produced at EOSDIS DAACs. imapp2daac tool simply adds some additional information to the IMAPP produced MODx data files. This makes them true HDF-EOS and similar to those produced at EOSDIS.
MODIS DB Algorithms
These are software tools to obtain some higher level MODIS
products. DB counterparts of EOSDIS production software use nearly the
same algorithms but are changed (or rewritten) in order to be used in
simplified environment convenient for DB users. Primary distribution
point for these code is at the
Direct Readout Portal.
MODIStools for ENVI
Modistools - add-in library for ENVI for work with the first levels MODIS data (i.e. MOD01-MOD02). This module contains functions that let to do following operations:
This library is available for free and may be downloaded from this site. See included text file for installation and usage notes.
HDFBROWSE.exe is a small command line utility that can be used to dump a one band slice of any HDF's SDS into a common image format (Windows BMP and TIFF). This tool was created having MODIS (and generally EOS-produced data, e.g. ASTER) data handling in mind. This is why it has several MODIS - specific features:
Short reference is included in the provided binary package. Extended version of the HDFBROWSE, which supports RGB synthesis and exports to JPEG and ECW, is available by request.
Commercial software from ScanEx
ScanMagic® - generic purpose program for visualizing, analyzing and processing remote sensing data. Among a lot of supported formats and data types it supports generic HDF files and offers extended possibilities to work with MODIS products.
