ArcPro 2.7.3 won't open ECW files

Ozplanman — Fri, 16 Apr 2021 03:48:15 GMT

I've recently upgraded to ArcPro 2.7.3 and the software gives me "unsupported data type' when I try toopen an ECW file. I thought this was fixed after version 2.1 or such?

Anyone know why?

It is on the list

Raster file formats—ArcGIS Pro | Documentation

What is the last version that you used that you could open them?

There are a number of outstanding bugs, for example...

BUG-000123365: Some Enhanced Compression Wavelet (ECW) files do not.. (esri.com)

There are more... just sort newest to oldest

I am running 2.7.3 here and my ECW files are opening ok. Do you have any other ones you can test with? Is it happening to all of them? Can you right click on it in the Catalog pane and choose Properties, if so what does it say?

Hi Dan, yes I checked that list. It seems random. I have ArcPro on my laptop at home and am sure it opens them there but this new install and upgrade to 2.7.3 doesn't want to open them. This is an ecw that I have used for years and which opens fine in ArcMap and everything else. Another undocumented enhancement I guess.

Hi Tim, no properties showing. As I mentioned above, it is an ecw I have used for years without issues...Cheers.

I have attached a small test ecw file that you can use to confirm that your Pro install can actually open and display them.

Unfortunately it does sound like an issue with that particular ecw file. Your best bet may be to open it on your laptop, get the file properties and contact Esri support for assistance.

Thanks Tim, appreciate the effort, but that's not necessary. I have the file open in ArcMap desktop, another of our staff have it open in ArcMap, it's not the file, it's just ArcPro being painful. 🙂

Great news! ..... sort of...

It opens brilliantly in ArcGIS Pro 2.8 Beta 1 (cool image BTW).

So if it opens in pre 2.7.3 and not in 2.7.3...

Tech Support it,
apply for the 2.8 Beta program,
roll back to 2.7.2 or
wait.

It just asked me to create statistics when I zipped up for you as an attachment if you want to compare to stats you may already have.

Hi Ozplaman, here is a quick turnaround for your problem. Open ECW file in ArcMap and save it map document file and now import map document file in ArcGIS Pro and see whether ECW reflects perfectly or not. Thanks.

Hi all,

Just thought I'd throw a quick resolution message here. Seems that ArcMap desktop and ArcPro don't always play nice and when you add other packages in there it becomes more fun. The ECW file that I have used for ages and which was the primary one which threw the error, has had an AUX and an XML file created for it by one package or other and ArcPro didn't like them. I deleted them and it opened it happily. I found this out by opening the original ECW in ERDAS Imagine and exporting it to a different ECW file in another folder. This new ECW of the same image, opened fine in ArcPro.

So, I should have realised that, given the pain we've had with AUX files in the past, that this was a likely issue. Blow away the unnecessary files which will be regenerated and it may work. Of course, next time I try and open it in ArcMap Desktop it will probably have a dummy spit!

Cheers all!

It is noted in the help files as well and world file behaviour can be controlled within ArcGIS Pro.

See World Files and Georeferencing in

Thanks Dan, however, ECWs haven't in my experience, ever needed "world" files and the creation of aux or xml files in ArcPro or other packages which creates issues in them being able to be opened in other packages is a giant pain when you are regularly using different components of a variety of software provided by different creators to get your job done! With resources in all areas being cut repeatedly, staff not being replaced and workloads not diminishing, having to spin your wheels finding solutions to problems that have been created where they didn't exist previously, is a pain.
