space as part of NASA’s Earth Observing System platform in December 1999. In

addition, Aqua MODIS was launched in May 2002. The objective of MODIS is to

provide a comprehensive series of global observations of the Earth’s land, oceans, and

MODIS data by reprojecting MODIS images (Level-2G, Level-3, and Level-4 land data

products) into more standard map projections. If desired, the user may reproject only

selected portions of the image (spatial subsetting) and only selected image bands (spectral

The heart of the MODIS Reprojection Tool is the resampler and mrtmosaic, executable

programs that may be run either from the command-line or from the MRT Graphical User

Tool. However, individuals with intensive data processing requirements are advised to

the GUI.

MODIS Data Products

The MODIS Reprojection Tool currently allows the user to reproject all gridded

(Level-2G, Level-3, Level-4) MODIS Land data products. Support for swath (Level-1

and Level-2) data products is available in the MRTSwath application.
