Huge fix to spatial data processing code for city scale visualisation with #rustlang: just merged. Great comms with reproducible example + tests = easy-to-follow + learn. Code is complex but outcome clear: better open source city simulations #abstreet 馃敟 https://github.com/a-b-street/abstreet/pull/1063
The root of most evil by dabreegster 路 Pull Request #1063 路 a-b-street/abstreet

Long long ago, #686 started taking advantage of the fact that all the numeric quantities in geom are rounded to a few decimal places, by serializing smaller integers instead of full f64s. But that ...

There is substantial prior art here but unfortunately not much in the way of reproducible code with open access data. Example from @DLR_en: https://www.dlr.de/eoc/en/desktopdefault.aspx/tabid-12760/22294_read-58694/ + cc @CarlinoDustin for #abstreet-esque city sim.
DLR - Earth Observation Center - DLR-SkyScapes: Aerial Semantic Segmentation Dataset for HD-mapping

High-Definition(HD) mapping is in many applications from autonomous driving to infrastructure monitoring, and urban management essential for the understanding of complex urban infrastructure with centimeter-level accuracy. Aerial images provide valuable information over a large area instantaneously; nevertheless, no current dataset captures the complexity of aerial scenes at the level of granularity required by real-world applications. To address this, we introduce SkyScapes, an aerial image dataset with highly-accurate, fine-grained annotations for pixel-level semantic labeling.

Great to see the latest features in #abstreet, live demo from @CarlinoDustin in #Leeds. This #opensource tool is increasingly being used in public consultations and rightly so. Ideal for enabling more evidence based and participatory transport planning.

Have you ever had an idea that could improve the rush hour traffic in your area? A/B street is a traffic simulator that gives you that ability.

It downloads data from #OpenStreetMap and simulates people driving to and from work. This gives you the option to try out things, and possibly improve the situation.

If you're really bold you can then bring this to your local politicians.
