Welcome to pyModisΒΆ

pyModis is a Free and Open Source Python based library to work with MODIS data. It offers bulk-download for user selected time ranges, mosaicking of MODIS tiles, and the reprojection from Sinusoidal to other projections, convert HDF format to other formats and the extraction of data quality information.

pyModis library was developed to replace old bash scripts developed by Markus Neteler to download MODIS data from NASA FTP server. It is very useful for GIS and Remote Sensing Platform of Fondazione Edmund Mach to update its large collection of MODIS data.

It has several features:

  • for downloading large numbers of MODIS HDF/XML files and for using it in a cron job for continuous automated updating; it supports both FTP and HTTP NASA repositories
  • parses the XML file to obtain information about the HDF files
  • converts a HDF MODIS file to GEOTIFF format by either using MODIS Reprojection Tool or GDAL (pyModis >= 1.0)
  • creates a mosaic of several tiles by either using MODIS Reprojection Tool or GDAL (pyModis >= 1.0)
  • creates the XML metadata file with the information of all tiles used for the mosaic
  • extracts specific information from bit-encoded MODIS quality assessment layers of different product types
  • Graphical User Interface for each script written in wxPython (pyModis >= 1.0)
