readMeta fails to read Landsat 9 metadata (*MTL.txt) files

[chevanik]

Hello,

I have been searching other threads in hopes to find an answer, but I am having a hard time doing so.
I am using Rstoolbox to process imagery from L9, L8, and L5 for a time series analysis.

I am using the most up to date package and Rstudio software.

LC09_L1TP_016032_20240301_20240301_02_T1_MTL.txt

My issues is with the MTL file for Landsat 9 imagery from March 2024. When performing the function to read in the metadata .txt. file, I keep encountering this error.

"> readMeta("E:/Ch1_veg_analysis/Landsat_master/Final_Scenes/LC09_L1TP_016032_20240301_20240301_02_T1_MTL.txt")
Error in rownames<-(*tmp*, value = tbds) :
attempt to set 'rownames' on an object with no dimensions"

I've also tried this iteration with no luck
" # 1a. Landsat 9; 03/01/2024

mtl9 <- paste0("E:/Ch1_veg_analysis/Landsat_master/Final_Scenes/LC09_L1TP_016032_20240301_20240301_02_T1_MTL.txt")
readMeta <- (mtl9) # read metadata file
summary(mtl9)
Length Class Mode
1 character character"

I've tried a few different iterations based on previous discussions here and on the geospatial data science in R website, and I'm at a loss with my troubleshooting. Any insight would be appreciated, apologies if I've missed any details - happy to correct if needed. Thanks

I have the same problem with this LT05 meta file:
https://www.dropbox.com/scl/fi/sl76rhvx4umhxj4ldzvtk/LT05_L2SP_009054_19870130_20201014_02_T1_MTL.txt?rlkey=fbidtw2rcm3picchwhc2h5h48&dl=0
I have compared it to the one used in the help page
system.file("external/landsat/LT52240631988227CUB02_MTL.txt", package="RStoolbox")
and they are very different.

I presume older issues #81 and #84 refer to the same problem and thus that there is little hope anyone is going to fix this function.
