modispythonpython-2.7
I need download Modis imagery automatically from the website: https://earthdata.nasa.gov/.
I found this link: http://gis-techniques.blogspot.com/2010/06/getting-modis-image-automatically-from.html
but I can't run it. In that code there's the line:
logFileread=open(r"D:\MODIS\MOD09\lpdaac.txt",'r')
I don't know the structure of this file.I don't know how to create it.
If anyone knows the answer, please tell me.
for my specific application, subsetting one band of the modis data to a specific region specified in -te, this seems to work:
gdalwarp -t_srs EPSG:32633 -te xmin ymin xmax ymax -tr xPixelres -yPixelres -srcnodata "32767" -r bilinear input_hdf-eos output.tif
hdf_eos should be in the form:
HDF4_EOS:EOS_GRID:/dir/to/MODIS.hdf:MOD_Grid_BRDF:Albedo_BSA_vis
for example, projecting the subdata set describing visible spectrum of Black Sky Albedo
The project website hosts the MOD16 dataset on an FTP server.
As FTPs allow directory listings you can easily download complete folders without having to click individual links. This can be done with most FTP clients - a popular one would be FileZilla. Just right click the folder you want and select download.
edit: The question now specifies that only one MODIS granule is required. There are two ways to achieve this:
Using the command line: Get a directory listing of all the files on the ftp, i.e. on linux with ncftpls -R, grep for the desired granule and download via curl/wget.
The easier way would be to use a dedicated ftp tool, search for the granule and download all files with it. @AndreJ already showed how to do this with fireFTP. The screenshot shows how you would do it in FileZilla.

You may also take a look at "pyModis", a Free and Open Source Python library to work with MODIS data. It can bulk-download, mosaik and reproject:
