converting multiple kea to tif

[Theo Awo]

Hi All,

Wondering if there's a way to use gdal_translate to bulk process the conversion of kea files to tiff instead of one by one using:

gdal_translate –of GTIFF filenam_demsref.kea filename_demsref.tif

Regards.

[Pete Bunting [pfb]]

Hi Theo, 

I use a shell script such as the one below:

# Created by Pete Bunting (peteb...@mac.com)

#

# A simple script to use gdal_translate to convert files 

# to the KEA format.

#

# Inputs:

# $1 is the input directory 

# $2 is the output directory

FILES=$1/*.kea

for f in $FILES

do

  echo "Processing $f file..."

  filename=`basename ${f} .kea`

  echo "Output: ${2}/${filename}.tif"

  gdal_translate -of GTIFF ${f} ${2}/${filename}.tif

  gdaladdo ${2}/${filename}.tif 2 4 8 16 32

done

Best wishes, 

Pete

A long time ago I wrote a script to do the opposite, converting .tif
GeoTiff files to .kea in Python, to reduce the size of stored Landsat
scenes.

Hi Theo,

Just to provide a pure python example:

import subprocess

import os

inDir = ‘infilepath’

files = [file for file in os.listdir(inDir) if file.endswith(‘.tif’)]

for file in files:

subprocess.call(‘gdal_translate -of KEA ‘ + os.path.join(inDir, file) + ‘ ‘ + os.path.join(inDir, file.replace(‘.tif’,’_kea.kea’)),shell=True)

Cheers, Nathan
