Error 1: maximum number of characters allowed

I am getting this error with some of my files:

ERROR 1: Maximum number of characters allowed reached.

using this function call:

"/Library/Frameworks/GDAL.framework/Versions/2.2/Programs/gdalwarp" -multi -overwrite -te 243981.149256099 4169328.58664336 316574.679779182 4239670.70617033 -te_srs "+proj=utm +zone=11 +datum=WGS84 +units=m +no_defs" -tr 1000 1000 -t_srs "+proj=utm +zone=11 +datum=WGS84 +units=m +no_defs" -r "near" -dstnodata "-99" -of "GTiff" "data/snodas/swe/conus/us_ssmv11034tS__T0001TTNATS2017120105HP001.Hdr" "data/snodas/swe/tuo/swe_tuo_20171201.tif"

you can download the files here:

Is there a character limit for lines in the header file?
Most of the other dates work fine, 20171101 is another example that doesn't work

I added a hack that mostly solves my issue but it'd be nice if that didn't have to happen!

I was actually using gdalUtils in R to use gdalwarp, but I confirmed the issue on the commandline.

in R, before using gdalUtils I added this chunk, where f is the filename of the .Hdr

library(tidyverse)

rl <- read_lines(f)
rl2 <- str_trim(rl)
rl3 <- map_chr(rl2,function(x){
    # print(x)
  if(grepl('BARD',x)){
    x <- 'BARD codes too long'
  } 
    return(x)
  })
write_lines(x=rl3,path=f)

@rouault for my own benefit, is 1024 a magic number or just a reasonable number to increase to from 256?

[rouault]

yes arbitrary number... One must put some limitation. I didn't research if SNODAS had some documentated limitation.
