ecw-to-tiff-conversion

Use the easy quick web service ECW to Tiff Online converter.

Or, build and run this locally yourself.

How to run it

There are two different ways to run the converter

1. As a web application (the default)
2. As a quick docker command without the web application

Run as a web application:

cd ecw-to-tiff-conversion
# change UPLOAD_FOLDER_MOUNT_PATH to the right setting
cp .env.example .env
docker-compose up --build

Run as a docker script, without needing the web application

Create a directory to store the file(s) you want to convert (e.g. 'uploads').

Run the command as follows:

• Argument one is the filename (not filepath) of the file you want to convert
• Argument two is the full path to the folder where you're storing the image

E.g.

 ./app/ecw-to-COG.sh my-image-file.ecw $(realpath ./uploads)

Don't know what realpath does? Or on Windows?

 ./app/ecw-to-COG.sh my-image-file.ecw C:\Users\Documents\uploads)

Your file will be converted into a GTiff file format, and placed into the uploads folder with the filename suffix _converted.tiff.
