Any reasons to stick with OTB 6.6?

I recently discovered that some people are still working with OTB 6.6, and it also seems that the future CNES GeoDataHub platform is based on 6.6, which I found quite strange.

So I wonder: what are the reasons to stick with such an old version?
GDAL2? Python2? Aren’t there any major bugs that were fixed in version 7.*?

Hi Vincent,

Thank you for your interest in GeoDataHub and OTB.
Where did you get this information about OTB 6.6 ?

I’ve discussed with my colleagues and it’s not that true : this web portal will embed image processings tools, like MAJA, S1-Tiling. Latest versions of these tools are based on latest versions of OTB (8.x). We will check if other processings need older versions…

Best regards,

Yannick

All right thanks for the clarification !

Ok, thanks for the link. I guess this documentation should be updated (at least when all geodes features will be accessible). And anyway, final users may not need to know exact version of each tool…

Until OTB 6, OTB used a specific library for argument parsing, which was quite useful to build your own command line application. With the launch of “OTB application”, these the argument parser was less and less used, therefore it was deprecated in an effort to reduce the number of dependencies at OTB 7. But maybe some “old” code still use this argument parser, therefore moving to OTB 7 requires additionnal efforts.
