I have a file with these information:

lat_min -60.0
lat_max 80.0
lon_min -180.0
lon_max 179.9
lon_sampling 0.1 degree
lat_sampling 0.1 degree
samples = 3600
lines   = 1401

I want to re-project the file to

I tried

 gdalwarp -of "ENVI" -t_srs `EPSG:3410`  -ts 1383 586 but give error
 gdalwarp -of "ENVI" -t_srs "+proj=cea +lon_0=0 +lat_ts=30 +x_0=0 +y_0=0 +a=6371228 +b=6371228 +units=m +no_defs" -ts 1383 586 -ot Float32  file.envi file_1383586.envi 
ERROR 1: No PROJ.4 translation for source SRS, coordinate transformation initialization has failed
  • If you want to resample your image to a given number of pixels you are looking for the -ts option instead of -tr which refers to the size of a individual pixel. Your command should look like: gdalwarp -of "ENVI" -t_srs EPSG:3410` -ts 1383 586 input.envi output.envi` Depending on your data I suggest also taking a look at the possible resampling algorithms which can be invoked with -r

  • Please provide more info on your error than 'but give wrong file'. What is wrong? Resolution, size, is there an Error message?

  • @hyat you need to convert the input file into something that GDAL can understand. As is, that is where GDAL throws the error. Commented Jun 11, 2015 at 11:50

  • GDAL could not find automatically the source srs, therefore it can't know how to do the conversion into your -t_srs. You must give also a correct -s_srs.

Since the files metadata is incomplete, you have to add it manually:

gdal_translate -a_srs epsg:4326 -a_ullr -180 80 179.9 -60 file.envi test.tif

and the result fits nicely to Natural Earth coastline, ready for further warping:

gdalwarp -of "ENVI" -t_srs "+proj=cea +lon_0=0 +lat_ts=30 +x_0=0 +y_0=0 +a=6371228 +b=6371228 +units=m +no_defs" -ts 1383 586 -ot Float32  test.tif file_1383586.envi

enter image description here

  • -a:srs? you mean -a_srs. I had an error ERROR 4: .envi' not recognised as a supported file format.`

  • I loaded the tif into QGIS, and the Natural Earth shape as well. You are right, -a:srs was a typo. Did you get the Error 4 with gdal_translate or with gdalwarp? I had no problem with the latest GDAL from gisinternals.

  • gdal_translate may be I have to install the same version of gdal you used.What you think?

  • Surely. Format drivers may have been improved. GDAL 1.11.2 is the latest stable. On Linux and MacOS, available drivers may be different.
