I don't have time right now to fully read the paper, but a quick glance at the abstract: "Our evaluations use NYC taxi trace data and an 80-server cluster. Results show that Pyro reduces the response time by 60X on 1km×1km rectangle geometries compared to the state-of-the-art solutions".

Congratulations to the authors.

Looks like an interesting paper, but I can't find any source code.

Thanks for your interests in our paper! We are refactoring the source code, and will publish it soon.

Hi Shen - The state-of-the-art spatiotemporal database systems are based on topological embedding and geometric interval computation (hyper-rectangle cell/simplicial complex https://en.wikipedia.org/wiki/Simplicial_complex).

And while I don't know of any open-source systems based on this design, SpaceCurve is publicly available (http://www.spacecurve.com http://www.jandrewrogers.com/2015/10/08/spacecurve/) , and I've heard systems like this exist within IBM and Google.

Have you looked into this approach?

Look forward to it!
