Re: [QGIS-Developer] ECW flags

[Walter Lorenzetti]

Hi Vincent,

I've to do it for a customer who bought OEM licence from Erdas.

Every time I try to push my customers toward free formats, sometimes I 
can, other times not :)


Have a good Sunday

Hi Walter,

Be careful with ECW SDK licence, which requires an OEM licence for any use in a
Server software component.

See for example :
https://community.hexagongeospatial.com/t5/APOLLO-ECW-Q-A/License-for-reading-or-writing-ECW-in-third-party-software/ta-p/34074#

This may have changed since 2019, but I doubt it.

In any case, I would rather recommend using an alternate format, with free and
opensource format and drivers.

Best regards,

[QGIS-Developer] ECW flags

[Walter Lorenzetti]

Hi all,

a question: QGIS-server 3.10.14 for Ubuntu it was compile with ECW flags 
or not?


With 3.10.12 iI can use gdal compile with Erdas libraries but I get this 
error with 3.10.14:


GDAL_ERROR 4: b"`/shared-volume/project_data/326152.ecw' not recognized 
as a supported file format."


Thanks in advance

Walter.

Paolo,

It's not so much that you can't change it it's just there a lot of
providers here in Australia to only give ecw out. Some of these files are
big as ecws so converting them to GeoTIFF would be impractical, plus a lot
of work and data storage. JPEG2000 is another option but unless the
providers change then user wont.

Regards,
Nathan

Once provided a comandline, perhaps with a simple webapp, this could

 sooner than later.
 
 It's up to you then.

I had a nice big rant, because this really ticked me off but I'll bring it back 
to a few fairly simple points. 

1. This is not about throwing money at a problem. It's a legal quibble problem. 
After that it might be a money problem.
1a. More importantly, for the *user* this is about removing easy access to a 
feature. (Translation: It's a regression).
2. This an option, but the plugin still needs to be there.
3. The ECW Project Manager has been asked for an opinion (the PSC has a copy), 
and I do not see this as incompatible with OSGeo4W continuing to provide the 
ECW plugin.
4. My major data providers do not yet provide Jpeg2000 as a standard option. 
This leaves me with options of an ECW which can probably be processed one day 
and emailed the next; or any other option which will go on a hard drive and the 
postal service will sit on (or kick around) for a week before it gets to me.
5. Yes, I agree they're bad. But there's a heck of a lot of legacy ecw around, 
particularly in Australia. (There's a lot of doc and docx around too)
5a. GDAL does a much better job of turning ecw into something else than 
anything else I've seen. But if ecw isn't accessible, then the data is 
effectively lost.

It's not just up to me. It's also up to QGIS to work out what sort of uptake it 
wants. Particularly here in Australia there is a *lot* of existing ecw, for 
example at the first Australian QGIS forum, ECW use ran at around 90%. It will 
make it extremely difficult to show off QGIS if it can't be easily shown to 
handle their existing data. Once we have the foot in the door then we can start 
the weaning process.

-ramon.

In case this triggers the don't say anything bad email, I'm writing this from 
my involved *user* perspective.  I'm also writing in a QGIS advocate sense. I'm 
not meaning criticism, but I am meaning to express serious concern that this 
one decision will make both my life as a user and particularly as an advocate 
in Australia much harder.

Yes. Very quickly too.

Because I look at this through a QGIS lens, the PSC has a copy of the 
correspondence. I'm not prepared to put it up on the mailing list. The essence 
though is that in the OSS setting, the installer of the SDK is deemed to be 
responsible for correct usage.

[Ecofuego]

The instruction I have provided are clear and tried and proven.  I am
successfully using ECW files thanks to Giovanni Manghi's instructions.  I
put them in here so that any user can install the GDAL-plugin simply and
with a minimal number of steps.

It also means that a user does does not paste dlls into the system
directories.  Instead only two files are copied to the appropriate
directories in the OSGEO4W folder.  It is that simple once one has obtained
the GDAL-ecw plugin and the library file from the MSI installer provided by
Giovanni.

I was going to write the same thing, ECW is proprietary viper's nest, 
the work to make it usable on QGIS should be done by ERDAS or by the 
people using it.


For those wanting a good wavelet format, there is OpenJPEG 2.0. If it 
doesn't fit the bill for you then they should think about supporting it 
like the CNES did instead of asking a open software to support a black 
box with a stupid license.

Re: [Qgis-developer] ECW!!!

[kimaidou]

Here is a very documented blog post about the comparative use of ecw or
compressed gtiff

http://blog.webmapper.com.au/

You can use basic gdal command line to get a compressed gtiff from ecw,
with very good performances. For example :

# convertir l'ecw
gdal_translate -of GTiff -co TILED=yes -co PHOTOMETRIC=YCBCR -co
COMPRESS=JPEG input.ecw output.tif
# créer la pyramide
gdaladdo -r average --config COMPRESS_OVERVIEW JPEG --config
PHOTOMETRIC_OVERVIEW YCBCR --config INTERLEAVE_OVERVIEW PIXEL
compressed.tif 2 4 8 16 32 64 128

Will provide a geotiff with great performances and not so big compared to
the ecw.

And as other suggested, open source wavelet is in progress too and must be
burried out !

self-defense...

1) from this archive (http://goo.gl/XiG21) copy gdal_ECW_JP2ECW into
C:\OSGeo4W\bin\gdalplugins\1.9 directory.

2) copy all other dll of previous archive in C:\OSGeo4W\bin and
C:\Windows\System32 directories

don't ask me why but it works!

this is valid, obviously fo sure in windows; i don't know for other O.S.
it works for brand new installation of qgis via osgeo4w both for 1.8 version
and dev. version

Re: [Qgis-developer] ECW!!!

[Ecofuego]

It is very simple for Windows.  This is based on Giovanni Manghi's web page
http://www.faunalia.pt/node/438

However, instructions for copying the dlls into their respective directories
are not clear.  

On Windows:

(1) install Quantum GIS with the osgeo4w installer
(2) install this package
http://www.gisinternals.com/sdk/Download.aspx?file=release-1600-gdal-1-9...\gdal-19-1600-ecw.msi;
(obviously without the inverted commas)
(3) using windows explorer go inside c:\program files\gdal and find the two
.dlls, libecwj2.dll and gdal_ECW_JP2ECW.dll
(4) copy libecwj2.dll into the c:\OSGeo4W\bin folder
(5) gdal_ECW_JP2ECW.dll into the c:\OSGeo4W\bin\gdalplugins\1.9
(6) start up QGIS into the osgeo4w folder
(7) add raster layer using add raster layer command
(8) select the image file ending in ecw

There you have it.  It should work.  I successfully loaded ecw files this
morning.

Thanks Giovanni

A slight revision.  I inserted the wrong link to the GDAL's MSI installer. 
The correct one is in place now.  It should work without a hitch.

 Lee and others managed to compile this ECW library for QGIS 1.7 for Ubuntu.

 I think it would to have ECW support as well in Mac OS X.

 William, would it be possible to try to compile this library and

 Reading from Build.txt, it has support for Mac OS X.

 Thanks in advance.

I'd be willing to take a shot at adding this to the Homebrew package

Re: [Qgis-developer] ECW Support Ubuntu 11.04 (Natty)

[Giovanni Manghi]

Hi Jože,

is easy, you need to install one package/script available in the
ubuntugis repository and then use this script to compile (with the ecw
sdk) the support for ecw into gdal. It is just one command and it takes
a few seconds.

http://trac.osgeo.org/ubuntugis/wiki/UserTutorials


The real problem is to have the SDK for Linux, that is no more available
on the ERDAS site.


For a long time I believed that this was not redistributable software
(the erdas sdk), but recently I spent a few minutes reading both the
licences of the new SDK -the one with just binaries for Windows- and the
one of the old SDK (the one that was in the form of source code and that
was still named after ER mapper).

I'm not into licences matters, so I would like to know what do you think
about.

To my understanding the .dlls of the new SDK are clearly
redistributable. This binaries have indeed limitations, as are only read
only and cannot be used in servers, but it seems to me that the could be
included in desktop software.

+++
this Agreement does not permit You to (a)
use the ERDAS ECW/JP2 SDK
Desktop Read-Only to create or distribute Server Applications or SDKs;
(b) use the ERDAS ECW/JP2
SDK Desktop Read-Only to create Libraries; or (c) distribute header
files or .lib Library files included in
the ERDAS ECW/JP2 SDK Desktop Read-Only

You may distribute with your End Application any
dynamically loadable object Libraries (.dll files) that are included in
the “redistributables” directory of
the ERDAS ECW/JP2 SDK Desktop Read-Only, and are used by your End
Application.
+++


If the old SDK licence was not voided somehow by ERDAS it seems to me
that it is pretty permissive. The document describes three different
licences, apparently the user had the chance to choose among them. The
two more interesting are:


+++
*) ECW JPEG 2000 SDK FREE USE LICENSE AGREEMENT.

b) You may install and use an unlimited number of copies of the ECW JPEG
2000 Runtime, which consists of files contained in the runtime
directory for use in Client Software. You may reproduce and distribute
an unlimited number of copies of the ECW JPEG 2000 Runtime for use in
Client Software; provided that each copy shall be a true and complete
copy, including all copyright and trademark notices, and that you comply
with the Distribution Requirements described below.  You may not use
Software Product for development or distribution of Server Software.
+++

+++

*) ECW JPEG 2000 SDK PUBLIC USE LICENSE AGREEMENT

The intent of this license is to establish freedom to share and change
the software regulated by this license under the open source model and
is applicable to the use of the ECW JPEG 2000 SDK with Unlimited
Decompressing and Unlimited Compression for applications licensed under
a GNU General Public style license (GPL) as set out below.
+++

Both seem to me to allow include the libraries in desktop software, the
second one even to server software.

It is indeed software that was last developed in early 2006... but still
working ok.


Cheers

I have also been looking at Jürgen's answer, and if I understand I should

Not from source.  The nightly builds use the GDAL version from the original
distribution.

My main point of the nighly builds is to test if trunk is building against the
various library versions - having usable trunk builds is just a side effect ;)

So if you need ECW support, you need to add it to that version.  The version
from ubuntugis is probably a different one and therefore not used by nightly
build.  And in turn having ECW support for that one, doesn't help.

You need to build the GDAL ECW plugin for the original GDAL version.  The
tuturial can help with that.  And once you added it, QGIS (including coming
nighly builds) will be able to use ECW.

I think I understand. I've had a go trying to turn understanding into 
practicality today, but for the moment, I'm plain out of time.

Jürgen, for a side-effect, this is the most pleasant one I've met for quite 
some time.



So the current situation for regular GIS users who need support for 
ecw is:

On windows -
You have a chance to get ecw support if you were lucky enough to 
download the previous ERDAS SDK 4.0 (which is no longer available). The 
latest one, 4.1 causes gdal to crash.

On Linux -
You're probably out of luck for now.

[Qgis-developer] ecw and linux nightly builds

[custard]

Hi, 

I've been happily running the development nightly builds on my linux (ubuntu) 
box for a while now. 

Unfortunately, I've just hit a point where unfortunately I have no real choice 
but to load up an ecw image. 

I have previously complied the ecw library (when using ubuntugis-unstable) and 
GDAL knows about ecw, but QGIS doesn't seem to want to talk to it. 

There doesn't seem to be a gdal-ecw (or similar) package in the nightly 
repositry. 

So 
Is it possible to add a package to the nightly build to get ecw support? 
or, 
Is it possible for me to build/add a linking bit (package) and get ecw support? 
or, 
Do I need to go into the self-build relm? 

If it's one of the first two, are there pointers available? 

-ramon.

Probably not the version that QGIS uses.  The nightly builds are done against
the normal version of the distribution.  You probably only have ecw support
for a version from a foreign repository.

If you add ecw support to the distribution's version, QGIS should also use it.

Re: [Qgis-developer] ecw and linux nightly builds

[Ramon Andinach]

Ah. I appear not to have been clear in my intent. Sorry.

I was using ubuntugis-unstable (which is 1.6) and had ecw support there. 
 (Giovanni, yes that method worked perfectly for 1.6)

I then moved to the nightly builds (by changing sources, and letting apt sort 
things out) so I could find out more about 1.7, and have been in blissful 
ignorance of the whole ecw problem (at least on this computer) for a couple of 
months. I'm now quite used to 1.7 (particularly the OTF rasters :), and would 
rather not have to go back to 1.6.

So the crux of the question should have been, Is there a (relatively) easy way 
to look at ecw rasters using the nightly build?




I have also been looking at Jürgen's answer, and if I understand I should 
remove the remaining GDAL bits from the 1.6 install and bring in GDAL from 
source (which should be what the nightly build is expecting), and hook ecw up 
to that. Then it should work. I'm probably misunderstanding - is that right?

-ramon.

 Hi,
 
 I've been happily running the development nightly builds on my linux
 (ubuntu) box for a while now.
 
 Unfortunately, I've just hit a point where unfortunately I have no
 real choice but to load up an ecw image.
 
 I have previously complied the ecw library (when using
 ubuntugis-unstable) and GDAL knows about ecw, but QGIS doesn't seem to
 want to talk to it.
 
 There doesn't seem to be a gdal-ecw (or similar) package in the
 nightly repositry.
 
 So
 Is it possible to add a package to the nightly build to get ecw
 support?
 or,
 Is it possible for me to build/add a linking bit (package) and get ecw
 support?
 or,
 Do I need to go into the self-build relm?
 
 If it's one of the first two, are there pointers available?
 
 -ramon.

Not from source.  The nightly builds use the GDAL version from the original
distribution.

My main point of the nighly builds is to test if trunk is building against the
various library versions - having usable trunk builds is just a side effect ;)

So if you need ECW support, you need to add it to that version.  The version
from ubuntugis is probably a different one and therefore not used by nightly
build.  And in turn having ECW support for that one, doesn't help.

You need to build the GDAL ECW plugin for the original GDAL version.  The
tuturial can help with that.  And once you added it, QGIS (including coming
nighly builds) will be able to use ECW.

[Qgis-developer] ECW Support in 1.6...

[Jože Detečnik]

Hello,

 

I don't understand why ECW support is not included in this version. GDAL
1.7.2 now support ECW, also I downloaded ERDAS SDK kit 4.1 last night.

I think a lot of users use ECW in their projects.

 

Thank you for answers and all good work you done.

 

Best regards, Joze.
