Hi,

I have some news regarding the rtree:

1. Segments are now supported by the rtree. They can be used as Indexables and stored directly in the spatial index.

Great news! This is really convenient. Thanks a lot.

Is it possible to have this in the docs too (including an example?)

Menelaos, does this mean that we should reconsider (probably after release) some implementations for distance?

Yes, we can.
I am not saying that using segments in the R-Tree would be better/faster. I am only saying that now we have one more alternative way for implementing distances, and in that respect it should be investigated.

We currently call point_range_to_geometry_rtree twice (in e.g. polygon-polygon distance). Now that Index supports segments, one call should be enough. So it should be faster (and better).

Regards, Barend
