Hi there. I am trying to modify WRF's default land use with the one I generated. The land use I have are with 6 categories only where I categorized urban with 5. The tif file is at 1 arc-second. I plan to use my generated LU in the fourth domain. My question is do I need to resample the image to 30 arc-second to coincide with either USGS or MODIS? Also, do I need to reclassify my LU categories following USGS/MODIS classification number? Say if my urban is 5, do I need to reclassify it to 13 (MODIS) or 1(USGS)? Thanks!. By the way my reference is using this tutorial http://www2.mmm.ucar.edu/wrf/users/tutorial/201901/duda_wps_advanced.pdf
