# Most simple ECW support for gdal on Debian 12 (bookworm)

Hugely based on https://github.com/interob/libgdal-ecw

This will also work on Debian 11 oldstable (bullseye)

## Rationale

GIS people usually do not care about the formats they are using but they

tend to care about storage space. For this reason customers often supply

their data in compressed form.

Unfortunately this often means that they use the patented and proprietary

ECW-format.

## To the recue

Hexagon Geospatial provides a proprietary library for reading ECW files:

http://download.hexagongeospatial.com/downloads/ecw/erdas-ecw-jp2-sdk-v5-5-update-4-linux

This said all you usually need in the world of FOSS GIS Software is support

in [GDAL](https://gdal.org/) thus this code will build a single self-sufficient

Plugin for GDAL using the proprietary ECW library which can be copied to /usr/lib/gdalplugins/

on Debian/Ubuntu based distributions.

## Installation

1. Install ``libgdal-dev`` package.

2. Clone this repository:

   ``git clone https://github.com/giggls/gdal-ecw-plugin``

3. Download and extract ``ECWJP2SDKSetup_5.5.0.2268-Update4-Linux.zip``. This

   will give you ``ECWJP2SDKSetup_5.5.0.2268.bin``

4. Put this file into the cloned directory and run

5. Call ``make`` which will give you a file called ``gdal_ECW_JP2ECW.so``

6. Copy ``gdal_ECW_JP2ECW.so`` into /usr/lib/x86_64-linux-gnu/gdalplugins or call

   ``sudo make install``.

7. Optionally call ``make mrproper`` which will remove the ``hexagon``

   folder from your home directory.

To check if this worked properly call ``gdalinfo --formats`` command which should

give you something like this:

```

 ~/ > gdalinfo --formats |grep -i ECW

  ECW -raster- (rw+): ERDAS Compressed Wavelets (SDK 5.5)

  JP2ECW -raster,vector- (rw+v): ERDAS JPEG2000 (SDK 5.5)

```
