I have a .dat file (ENVI format) with specific band names, as you can see in the snapshot.

ENVI snapshot

I've imported this file in R, but I cannot find the band names in the R object. The command

names(stack_NDVI)

gives this output

[1] "old_min_identification_VI_smooth_2010.1"  "old_min_identification_VI_smooth_2010.2" 
 [3] "old_min_identification_VI_smooth_2010.3"  "old_min_identification_VI_smooth_2010.4" 
 [5] "old_min_identification_VI_smooth_2010.5"  "old_min_identification_VI_smooth_2010.6" 

that is not correspondent to the band names of the .dat file as I can see in ENVI.

Any ideas to get this information fro the R object?

I've imported the .dat as a RasterStack object.

  • Do you have a .hdr with the .dat file?

  • @Iris yes I have the .hdr. All the band names are stored there.

    I think it is easiest to copy the band names from the hdr file and rename the band names of the rasterstack afterwards using names(stack_NDVI) <- c('a','b','c')

I had the troubles myself and couldn't find a solution. To export and import rasters between ENVI and R and keep the band names seems impossible (cf. this related question).

A workaround is to copy the band_names from the .hdr file and rename the band names from the imported rasterstack.

band names = {a,b,c} copied from file.hdr

image <- stack("file.dat") 
band_names = c('a','b','c')
names(image) <- band_names
