The tools listed below can be used with MODIS data. Some were created by NSIDC and some were created by other sources. NSIDC only supports and maintains those tools that reside on the nsidc.org domain.
NSIDC ToolsThe MODIS Swath-to-Grid Toolbox
The MODIS Swath-to-Grid Toolbox (MS2GT) is a set of software tools that reads HDF-EOS files containing MODIS swath data and produces flat binary files containing gridded data in a variety of map projections. MS2GT can produce a seamless output grid from multiple input files corresponding to successively acquired, 5-minute MODIS scenes.Hierarchical Data Format - Earth Observing System (HDF-EOS)
Hierarchical Data Format (HDF) is the standard data format for all NASA Earth Observing System (EOS) data products. HDF is a multi-object file format developed by The HDF Group. NSIDC created this site to answer common questions about HDF-EOS and to provide simple methods for working with the HDF-EOS format. Please note that NSIDC does not maintian the HDF Group libraries.
Tools from Other Sources
Note: NSIDC does not support or maintain the tools listed below.HEG HDF-EOS to GeoTIFF Conversion Tool
This free tool converts many types of HDF-EOS data to GeoTIFF, native binary, or HDF-EOS grid format. It also has reprojection, resampling, subsetting, stitching (mosaicing), and metadata preservation and creation capabilities.NCSA HDFView
The HDFView is a visual tool for browsing and editing the National Center for Supercomputing Applications (NCSA) HDF4 and HDF5 files. Using HDFView, you can view a file hierarchy in a tree structure, create a new file, add or delete groups and datasets, view and modify the content of a dataset, add, delete, and modify attributes, and replace I/O and GUI components such as table view, image view, and metadata view.The MODIS Conversion Toolkit (MCTK)
An ENVI plugin that can ingest, process, and georeference every known MODIS data product using either a graphical widget interface or a batch programmatic interface. This includes MODIS products distributed with EASE-Grid projections.MODIS Reprojection Tool (MRT)
MRT is software that re-projects MODIS Level-2G, Level-3, and Level-4 land data products. The MRT currently supports MODIS land products in the Integerized Sinusoidal and Sinusoidal projections.MODIS Reprojection Tool Swath (MRTSwath)
MRT Swath is software that reads HDF-EOS files containing MODIS swath data and produces native binary HDF-EOS Grid or GeoTIFF files of gridded data in different map projections.
