convertmodis module

Convert MODIS HDF file to GeoTiff file or create a HDF mosaic file for several tiles using Modis Reprojection Tools.

Classes:

• convertModis

• createMosaic

• processModis

Functions:

• checkMRTpath()

pymodis.convertmodis.checkMRTpath(mrtpath)

Function to check if MRT path it correct

Parameters:

mrtpath (str) – the path to MRT directory

Returns:

The path to ‘bin’ and ‘data’ directory inside MRT path

class pymodis.convertmodis.convertModis(hdfname, confile, mrtpath)

Bases: object

A class to convert modis data from hdf to tif using resample (from MRT tools)

Parameters:

• hdfname (str) – the full path to the hdf file

• confile (str) – the full path to the paramater file

• mrtpath (str) – the full path to mrt directory which contains the bin and data directories

executable()

Return the executable of resample MRT software

run(quiet=False)

Exec the convertion process

class pymodis.convertmodis.createMosaic(listfile, outprefix, mrtpath, subset=False)

Bases: object

A class to convert several MODIS tiles into a mosaic

Parameters:

• listfile (str) – the path to file with the list of HDF MODIS file

• outprefix (str) – the prefix for output files

• mrtpath (str) – the full path to mrt directory which contains the bin and data directories

• subset (str) – a string composed by 1 and 0 according with the layer to mosaic. The string should something like ‘1 0 1 0 0 0 0’

executable()

Return the executable of mrtmosaic MRT software

run(quiet=False)

Exect the mosaic process

write_mosaic_xml()

Write the XML metadata file for MODIS mosaic

class pymodis.convertmodis.processModis(hdfname, confile, mrtpath)

Bases: object

Parameters:

• hdfname (str) – the full path to the hdf file

• confile (str) – the full path to the paramater file

• mrtpath (str) – the full path to mrt directory which contains the bin and data directories

executable()

Return the executable of resample MRT software

run(quiet=False)

Exec the convertion process
