Dear all,
I try to georeference modis on polar2grid. I have modis data in : https://1drv.ms/u/s!AjXAWS5maHffhxqFXLF ... q?e=TpUlDl
It fail when I run polar2grid. The message like this :
mega@mega:~/Documents/polar2grid_v_2_3
$ polar2grid.sh modis gtiff --list-products -f /home/mega/Documents/polar2grid_test/modis/input/a1.20315.0552.seadas.hdf
INFO : Initializing reader...
ERROR : modis frontend failed to load and sort data files (see log for details)

When I try using test data, it succeed :
mega@mega:~/Documents/polar2grid_v_2_3
$ polar2grid.sh modis gtiff --list-products -f /home/mega/Documents/polar2grid_test/modis/input/MOD02HKM.A2017078.1630.006.2017079013641.hdf

Any solution?

Hello Mega,

The problem you are having is that the SEADAS "a1.20315.0552.seadas.hdf" files are not supported in Polar2Grid.

The Polar2Grid documentation includes information about the Level 1B file formats and naming conventions that are supported:

https://www.ssec.wisc.edu/software/pola ... modis.html

For example,

a1.17006.1855.250m.hdf, a1.17006.1855.500m.hdf, a1.17006.1855.1000m.hdf, a1.17006.1855.geo.hdf

or

MOD021KM.A2017004.1732.005.2017023210017.hdf, MOD02HKM.A2017004.1732.005.2017023210017.hdf, MOD02QKM.A2017004.1732.005.2017023210017.hdf, MOD03.A2017004.1732.005.2017023210017.hdf

Good luck,

Kathy
