gdal:2.4.4_ECW Docker images (with Python 3).

docker run --rm -it ginetto/gdal:2.4.4_ECW

Using a data volume

$ export DATAFOLDER="-v /folder_with_your_testdata/:/home/datafolder"
$ docker run $DATAFOLDER --name gdalecw -it --rm ginetto/gdal:2.4.4_ECW /bin/bash

if my ECW image is /path/to/my.ecw I can convert with:

docker run --rm -it --name gdalecw -v /path/to/:/home/datafolder
            ginetto/gdal:2.4.4_ECW
            gdal_translate
                /home/datafolder/my.ecw
                /home/datafolder/my.tif

Use -u option in docker run command to avoid to have result with uid=0 (root). See https://docs.docker.com/engine/reference/run/

see guides in: http://blog.cleverelephant.ca/2015/02/geotiff-compression-for-dummies.html https://kokoalberti.com/articles/geotiff-compression-optimization-guide/

apply optimization as -wo options to gdal_translate command

$ git clone https://github.com/luipir/docker-gdalecw.git
$ cd docker-gdalecw
$ docker-compose up

This will create and run automatically ginetto/gdal:2.4.4_ECW image.

To build with other gdal version see: docker-compose.yml build args.

Building process would download ECW redistributable installer, but the way to download it can change due to decision about this proprietary driver. During time, ECW installer can change the way to download. Adapt Dockerfile reflecting these changes. Actually the Build is based on downloading the following ECW installer:
