Questions tagged [modis-reprojection-tool]
Modis reprojection tool (MRT) enables users to read data files in HDF-EOS format (MODIS Level-2G, Level-3, and Level-4 land data products), specify a subset or specific science data sets as input to processing, perform geographic transformation to a different coordinate system/cartographic projection, and write the output to file formats other formats. It comes in Linux, Windows, and Mac flavors with Linux having a 64-bit option. It requires JRE.
