error in running geogrid

[Chitta Ranjan Dash]

Hello,
I am using MODIS 500m, MCD12Q1 land cover data 2010 for my parent domain from Google Earth Engine in .tif file format. The data is of "WGS-84". I reprojected it into EPSG:4087 - WGS 84 / World Equidistant Cylindrical then converted it into binary format by using "gdal_translate -of ENVI foo.tif data.bil" and renamed it using "mv data.bil 00001-ncols.00001-nrows". I prepered an index file and updated the GEOGRID.TBL.
I am facing error in running geogrid it shows invalid category. I am attaching the necessary file. Suggest improvements in index file or any other.

Thanks.

Hi,
With this data type, do you know how many categories it should contain? Can you attach the full geogrid.log file? Thanks.

Thanks for your reply.
Now its solved. I used convert_geotiff function, using "./convert_geotiff -c 17 -t 2400 -u categorical new.tif" then it created 20 binary files along with index file. Now I successfully completed the geogrid run. I plotted the "LU_INDEX" and its updated. I have one question.
my land use data has 17 categories when i checked the met_em.* files there it is showing num_land_cat = 21 but when i plotted the "LU_INDEX" it showing the updated one. why ?

I'm so glad to hear the issue has been resolved. Since your original question was about geogrid, and this new question is a bit different, if you're still confused, do you mind starting a new thread for that one? Keeping each post focused on one issue makes the forum easier to read and search in the future. Thanks!
