Summary
Abstract: The MODIS Swath Reprojection Tool (MRTSwath) provides the capability to transform MODIS Level-1B and Level-2 land products from HDF-EOS swath format to a uniformly gridded image that is geographically referenced according to user-specified projection and resampling parameters. Correction for oversampling between scans as a function of increasing (off-nadir) scan angle is performed (correction for bow-tie effect).

Any of the input HDF-EOS Science Data Sets (SDSs) may be selected for processing, and a spatial subset can be defined by a rectangular subset of the input data. The subset area is defined by the upper-left and lower-right corners expressed as input latitude and longitude, input line and sample pairs, or output projection coordinates.

During reprojection, the data may be resampled using the nearest neighbor, bilinear, or cubic convolution methods. Datum conversions are not supported by the MRT Swath. Format options for output files include HDF-EOS, GeoTIFF, and generic binary. The MRT Swath is executed through a command line interface.

MODIS Level-1B data are processed and by distributed by the Goddard Earth Sciences Distributed Active Archive Center (GES DAAC) and by MODIS Direct Readout stations. The MODIS Level-2 land products are distributed by the Land Processes Distributed Active Archive Center (LP DAAC) located at the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center (EROS).

The MODIS Swath Reprojection Tool is available to all registered users. This software will undergo further enhancements to correct problems that are identified, incorporate new functionality, and be modified to improve computational performance. The funding support for this work comes from the NASA Earth Science Data and Information Systems (ESDIS) Project. There are no restrictions on the use or redistribution of this software.
