[pgrouting-dev] MOTION 2: Stop 2.x series support

[Regina Obe]

I don’t think it will be in PostGIS anytime soon and even if it is it would be thru SFCGAL which is not a hard dependency.

I am working on a revised ST_ConcaveHull (faster and more accurate) which could act as a proxy but I’m not sure I’ll be done with it before 3.1 and even so, many users would be using lower.

 

Also keep in mind what Darafei said in his blog post.  He thought AlphaShapes are a poor solution for pgRouting.

I understand the reasons for dropping CGAL and I think it's a good idea to lower the amount of maintenance effort. 

This is just a single function that probably only has a few users and it requires a lot of attention.

Because I and my company do not use the alphaShape function at the moment, it's also easy to agree.

 

That said, I'm not really sure if alphaShape will be part of PostGIS any time soon. 

Is there someone working on this? Is there a feature request issue already?

If not, we should probably create an issue and reference it to the one on pgRouting to drop CGAL.

 

Regards,

Daniel
