Didn't that also work in the GIS sector? When I started, there were a few top dogs (e.g. ESRI) that dominated the market. In the meantime, a lot has been standardized via the OGC, also due to pressure from the open source community. We actually also supply geodata? Is there actually also a working group for point cloud data?

I think there are still significant cultural differences between the laser scanning community and the larger GIS/geospatial community, which as you say has been quite successful at adopting open standards and improving interoperability over the last couple decades.

When this petition came out I was a bit critical of it, largely because it seemed to be taking a much less proactive approach than what I've seen be successful in the GIS and other industries. Now that it's been adding subscribers for a couple years I'd be curious to hear from the original authors how successful they think it has been? Have you been able to get hardware and software vendors to provide the kinds of SDKs you were looking for? If so, I think it would be a great idea to highlight which ones are doing a good job directly on the web page so they get some recognition.

When this post was written, I was importing FARO Scene project files (*.lsproj) directly to Cintoo Connect or I could import FLS files to Cintoo Connect.

Since then, they have made so many major improvements. New scanners, new SCENE, new mobile software to improve registration, Flash 30 second scans, new Panocam scan processing to make the external panoramic pictures match the scan, but when it comes to SDKs, they have moved backwards. I spent 8 hours yesterday exporting a scan to RCP to upload to Cintoo.

There is a huge push from the U.S. Federal Department of Transportation to adopt Scan to BIM technology in Civil Projects right now. Our former Division Chief was part of the Team that worked at the FED from 2015 through COVID to develop this. It follows on other developments within the Fed GSA unit.
Depending on the size of the Scanning market in the US, I think if all 50 State D.O.T's as well as major county D.O.T's and Building management Divisions throughout the US get on board with this- it might bring the type of pressure we need to see the boards of the corporation take note as much as they do from their bean counters and their silo'd shareholders

Dear Jed,

thanks for your honest comment!

It was clear from the very first written line of this petition that there would be no "Hip hip hooray's" from the big manufacturers as a response to this. Which is understandable to some degree - some see / saw it as a direct thread to their business models (while some see it as a chance to see their data everywhere). Plus, why change something that is at it is for 20+ years?

Hence, it was also clear that it would take a lot of discussions behind closed doors. One company required two (!) years to understand that their actions of forcing clients to use independent exhange format effectively locks their own original data out of their own post processing eco-system.

Now to your vital question: Am I happy with the outcome? Well, yes and no!

Yes: Out of the three NASDAQ listed scanner companies two have introduced new interfaces (at no charge!) to various other hard- and software makers. For our software (+3 new interfaces to scanner manufacturers we didn't have before +2 new interfaces to other indenpendent software) and various other befriended companies this was a huge step forward. A very nice side effect were new cooperations and interfaces to other companies that didn't exist before. The biggest reward was actually talking to some service providers who told me (in the unit of Euro's) how much they save compared to before new interfaces were implemented.

No:

Initially, the idea was to post every new interface on the petition's homepage as well as Linkedin to highlight progress and of course to put pressure on "the others". Yet, some manufacturers did not want to be written about these new interfaces. Some interfaces cannot even be found in the release notes of the exporting software which is odd to say the least. Maybe your post will change my colleagues' minds : )

All the best

Dear Johannes,

the idea of this petition was never "E58" or something like this. I definetly agree that independent file formats (such as E57 and las) are extremely important to exchange data with the end client or as plan B to take a detour in other software without direct interface. Yet, they should be avoided in the production process due to ineffectiveness.

The idea was to being able to minimise data volume / archiving junk as long as possible due to what I called "evil digital twins". That means that I need to take care of let's say three different versions of point clouds that essentially contain the exact same information in different file formats or versions. Another problem are dialects where one software interprets certain information in a different way. Then there is of course optimised file access speed and of course no loss of attributes.

Sidenote: there is a working group within the OGC that copes with point clouds. https://www.ogc.org/about-ogc/committee ... ing-group/

All the best

Daniel
